Hi Holger Thanks for getting back to me. After analyzing the issue, I believe the issue is the overrun error the USART reports. The issue appear to stem from the fact that each byte received by the USART is handled in the interrupt handler, but the USB sending code locks out the interrupt for the entirety of its call. So I change the code in the following manner and it appears to solve the issue for me: 1) Increase the small buffer to be large enough to hold 1 typical apdu: 270 bytes: 4 byte SIMTrace header, 4 byte command, 2 byte status, 1 byte instruction that appears to be repeated?? 256 bytes payload 2) Disable USB interrupt before deciding to Continue to send stuff to USB until returning from function. 3) lock out interrupt ONLY when retrieving a new req_ctx to transmit to USB 4) Some additional code change to detect if a req_ctx is completely transmitted .. 5) An additional function call in the main loop to detect (and output to debug serial) if an overrun occured Attached is my diff file based on what's in git. Let me know if it works for you On Thu, Aug 8, 2013 at 9:58 PM, Holger Hans Peter Freyther < holger(a)freyther.de> wrote:

thank you for the analysis and the change! Would you like to create entire git commits for the various things and follow the kernel coding style?

...

5) An additional function call in the main loop to detect (and output to debug serial) if an overrun occured

great! We have a slightly different coding style but the change itself looks good and I would support it to be included.

...

1) Increase the small buffer to be large enough to hold 1 typical apdu: 270 bytes: 4 byte SIMTrace header, 4 byte command, 2 byte status, 1 byte instruction that appears to be repeated?? 256 bytes payload

this seems reasonable. Using git gui blame on the req_ctx.h I notice that this has already been increased for the SIM, increasing it further can make sense.

...

2) Disable USB interrupt before deciding to Continue to send stuff to USB until returning from function. 3) lock out interrupt ONLY when retrieving a new req_ctx to transmit to USB 4) Some additional code change to detect if a req_ctx is completely transmitted ..

I can't comment on these three as I have not looked into the inner workings of the USB code yet. I would propose we start with creating three git commits for the first three things and then look into locking/disabling irqs. thanks a lot holger

I applied this patch and it seems to have fixed my dropped byte issue. Before the patch I could not capture more than ~10 APDUs without dropping bytes, now I am getting through the entire startup sequence (600+ APDUS) Thanks for the change!

Thanks for the feedback Rupert. Holger I am not familiar with git... but isn't there access restrictions on commit to the git similar to svn? If not, then I would try commit it later this week. Thanks On Tue, Aug 13, 2013 at 3:36 PM, Rupert Lloyd <rupert.lloyd(a)gmail.com>wrote;wrote:

Hi, Thanks for working on this. Min Xu wrote:

An important difference between git and svn is that git is distributed instead of centralized. This means that every developer starts with an identical copy "a clone" of the osmocom.org repository in their worktree, and everyone can create commits locally. Complete commits can then be transfered between developers by a few different means, one of which is email. This significantly reduces workload of project maintainers, since they can include well-formed commits from other developers very quickly. A git commit includes both author and commiter information, and the commit message, so one effect of using git is that new developers can easily contribute directly to the main repository, by sending a commit they have created locally via email to the project. If you can send email on the workstation where you run git, you can use the git send-email command (with appropriate parameters). If you need a separate patch file to attach in a standalone email program you can run git format-patch (with appropriate parameters, such as -1 in order to generate a patch file for the last 1 commit). Please configure git with your name, and please follow the common practise for commit messages; on line 1 a short (<=72 chars) summary, line 2 blank, line 3 and onwards a longer description and rationale for the change. Try to keep lines 3 and later <=74 chars. I recommend the book "Pro Git" at http://git-scm.com/book as well as the more lightweight Git Reference at http://gitref.org/ and the #git IRC channel on irc.freenode.net for community help. //Peter

There is also git imap-send, which can be easier to set up when no MTA is running on the machine where git is used. Kind regards, -Alexander Huemer

Thanks again for analyzing the problem. I was pondering to apply your patch, but think a different approach might be better: Use the USART DMA mode. Thiss way we don't get one interrupt per character, but one interrupt every 'dma buffer size' characters. Using double buffering we should be able to always process one particular dma buffer, while the other buffer is being filled by the hardware without interrupts. Processing of the DMA buffer could happen either in an interrupt handler of the PDC (dma controller) or even in the main loop. Unfortunately the SAM7S USB controller does not support DMA, so it is impossible to improve on that side. I will give this some more thought. If I'm unable to implement this within short time, I might merge your patch anyway as a interim fix.

Hi Harald I made a bunch of changes that significantly improved my test scenario: Before the changes, the LTE SIM card being traced on a USB modem would fairly consistently "restart" the simtrace board (I later found out that the WDT was kicking in). And the same sim card on a Galaxy SII phone would get corrupted data (ie., wireshark would no longer be able to follow the conversation) The changes are as follow: 1) The req_ctx are loaded into a double-linked list for consistency (FIFO manner). Previously, in the old code when multiple req_ctx are ready for transmit to USB, the lowered numbered (which may be the most recently filled req_ctx) would always be transmitted first. Additionally, to simplify the queue, there is only a single sized req_ctx now, 1 kb. There are 19 of them allocated. 2) The debug ring buffer is now transmitted using Peripheral DMA. Receive is left alone. Also, the append/flush and AT..._PrintFrame is written to allow for re-entrance (via Interrupt handler). Additionally, debugp will always prefix a line number to help / assist in debugging. 3) The watch dog (wdt.c) is modified so I can see when the watch dog is activated (which it no longer does in my current test, so you can comment out the #define WDT_DEBUG line...) 4) Both the usb interrupt and the uart interrupt handlers first enable core interrupt so that the AIC can do interrupt nesting (I observed at least 1 uart overrun per DEBUGPCR prior to these changes) 5) Minor additional debugpcr in req_ctx_init and in udp_refill_ep to indicate where the req_ctx are and containing what data to assist debug Please review and comment Issues I will work on further: 1) The first APDU after the ATR is almost always broken up (I don't think it's due to my changes). And occasionally, the length byte (p3?) sometimes is missing (ONLY on this LTE sim card / MODEM). 2) I need the simtrace to transmit a complete APDU as soon as possible. It seems not consistent on when it sends out received data to the USB. Sometimes, I would see GSM AUTHENTICATE apdu without a response for quiet a while... ---- I would like to have an additional field (2 byte short) in the simtrace header (the beginning of the req_ctx to indicate the position of the first byte of an APDU, so that in the event the synchronization is lost, the pc side can recover, because it appears the firmware code tracks the state of the APDU so it should be able to indicate it.

I made a bunch of changes that significantly improved my test scenario:

I _really_ appreciate your excellent technical work. However, I would like you to go the little extra effort it takes to 'properly' interact with community based Free Software projects, where there are rules like * only one feature / logical change per patch, resulting in a series of incremental patches, each taking us one step further, each rendering a compile-able and functional build after being applied. * no re-formatting of code (whitespace changes) * no patch for local changes like different compiler name in Makefile * stick to coding style of the project (tab-wide indent, ...) for consistency * remove old/dead code rather than comment it out (RCTX_STATE_...) * avoid asm() statements whenever possible. If you need them, please wrap them in an inline C function with descriptive name. Some quesetions: * why did the numberic values of RCTX_STATE_* have t be changed rather than amended by your new values, keeping the old ones as-is? * interrupt nesting _should_ have been active all the time, see IRQ_Handler_Entry in Cstartup.S, where we first save SPSR and then un-set the IRQ and FIQ bits _before_ branching to the interrupt handler function: /*- Enable Interrupt and Switch in Supervisor Mode */ msr CPSR_c, #ARM_MODE_SVC Where ARM_MODE_SVC is set to 0x13, i.e. without 0x40 or 0x80. So if there's something wrong with the existing code, it should be fixed there rather than two copies of inline-asm in the USART and USB IRQ handler routines. So I do want to merge this very much, but I think it needs clean-up before it can be merged. I don't expect to have much time for this in the next couple of weeks, so I would be happy if either you or somebody else on the list could work on this. Regarding your comment about changing the USB protocol: This would lead to host / firmware version incompatibilities, and I'd like to avoid that if possible in any way. We already have the simtrace_hdr.flags structure member, which contains things like SIMTRACE_FLAG_ATR. I'm not sure if I understand your request fully, but why not simply add flags like: * First fragment of a fragmented APDU * More fragments to follow for this APDU This way a new APDU still has to start at the beginning of a USB transfer, but no changes to the simtrace_hdr are required.

Hi Harald Thank you for getting back to me so quickly. I am using Emacs on an Ubuntu netbook to do the edits, which likes to reformat sections as I move (copy/paste section around) and I haven't figured out a command to undo those changes. It'd be nice if there is a .emacsrc or something that automatically formats the code to the project standard? (presumably someone has one? ..) I started only wanted to make one change and submit (was initially the req_ctx), but couldn't reliably verify it until the debugp was working better without affecting the system, so the changes ballooned up to this stage. So I wanted to submit the changes before I change the code further. I will try limit the scope of changes in my future updates. To your questions: 1) The numerical values of the RCTX_STATE are changed to facilitate the choosing of the FIFO/double linked list of req_ctx to use. An array of FIFO, using the state to index into the array to get the FIFO is simplest. When I looked how the reqctx_find / ... functions are used, I found all callers use the constant name rather than any specific numeric value. 2) I will look at this tomorrow. But I was under the impression on how the lib_Atmel?? (sorry, can't access the source at the moment) was invoked to install the irq handler, that the entry point to the interrupt would be directly the function passed in. I looked at the sysirq_handler.c?? more closely than the other so I wasn't aware of the Cstartup.c file Since I increased the req_ctx buffer size to 1kb each, most req_ctx that are transferred to pc contain many many apdus but very often, the req_ctx do not begin at the start of an apdu. So I would like to have an offset (2 byte, since it could be > 256) to indicate the position of the first start of an apdu. After thinking about it more, I would also like to add a sequence number into the header (making the header 8 bytes then?) to better allow for detecting dropped req_ctx (if there are any..). The offset would be 8 for a req_ctx that starts with a new APDU, and would be 0 for an req_ctx that only contains a middle or last fragment of an APDU. I have already modified the host software to run on Windows (currently using Windows 7 x64), so I will probably make those changes locally only to help me detect any problem I might still be facing. Again, thank you very much for getting back so quickly, and I appreciate your product very much. Best Regards On Wed, Sep 4, 2013 at 9:31 PM, Harald Welte <laforge(a)gnumonks.org> wrote:

Hi All I have been debugging some usb errors that I have been encountering and here are my conclusions: -- The error is a BULK IN transfer error, after adding further code to display the internal message: BULK IN transfer error; rc=-5 : libusb0-dll:err [_usb_reap_async] reaping request failed, win error: A device attached to the system is not functioning. -- BUT when I used USBLyzer to analyze the underlying problem, it's actually a [buffer overflow] problem. 1) According to usb specification, USB full speed device maximum data packet payload size is 1023 http://www.usb.org/developers/docs/usb_20_070113.zip 2) According to the AT91SAM7S device specification, its USB endpoint size is 64 bytes. 3) According to libusb api description, bulk transfer overflow is caused by too small buffer ( http://libusb.sourceforge.net/api-1.0/packetoverflow.html ). Should use multiple of the device payload size. 4) Since we don't have a size indicator in our USB protocol (our header is 4 bytes, indicating ATR, wait timeout flag etc), the client software must not see more than 1 req_ctx per bulk_usb_transfer call Therefore, we SHOULD:

...

> A << Use a multiple of 64 bytes as req_ctx size, and must be <= 1023

[per USB specification]. I chose 960. Consequently, there is only ONE size for req_ctx, no more large / small)

...

> B << Desktop/Host software MUST use the same size in static void

run_mainloop(struct usb_dev_handle *devh). Otherwise, multiple req_ctx WILL be combined by the usb driver / libusb and the additional req_ctx header in the middle will confuse the apdu_splitter On Wed, Sep 4, 2013 at 10:37 PM, Min Xu <mxu(a)sanjole.com> wrote:

Hi All Further runs (after the check in) shows that there is still a chance for the req_ctx being transmitted by the atmel chip to be broken up (and consequently, also combined with a later req_ctx). From what I have read in the usb specification, there isn't anything to signal an end of stream other than the device stop transmitting for a little while. So I firmly believe we must expand the USB protocol header to add a length field (and I would also recommend adding some additional fields for housekeeping to ease future debug, e.g., address of the req_ctx, and offset of the first byte of an apdu). If this is not agreeable, I will refrain from further check-in, but I believe this change is a requirement to keep in-sync ----------- ============================ HOST SOFTWARE ============================ [[ OMITTED ]] [000078] USBT(D=002049E8, L=0738, P=02) H4/T4: B2 43 05 84 / B2 01 04 B0

I forgot one more thing: In my SERIAL OUTPUT section quoted earlier, please note there were some UART parity error ( there were 3 errors total, cumulative report ) Does anyone have any input on how to fix that? Do we need shielded cable or is it something we should fix in software? Best Regards On Tue, Sep 10, 2013 at 4:51 PM, Min Xu <mxu(a)sanjole.com> wrote:

However, I would like you to go the little extra effort it takes to 'properly' interact with community based Free Software projects, where there are rules like * only one feature / logical change per patch, resulting in a series of incremental patches, each taking us one step further, each rendering a compile-able and functional build after being applied. * no re-formatting of code (whitespace changes) * no patch for local changes like different compiler name in Makefile * stick to coding style of the project (tab-wide indent, ...) for consistency * remove old/dead code rather than comment it out (RCTX_STATE_...) * avoid asm() statements whenever possible. If you need them, please wrap them in an inline C function with descriptive name. Some quesetions: * why did the numberic values of RCTX_STATE_* have t be changed rather than amended by your new values, keeping the old ones as-is? * interrupt nesting _should_ have been active all the time, see IRQ_Handler_Entry in Cstartup.S, where we first save SPSR and then un-set the IRQ and FIQ bits _before_ branching to the interrupt handler function: /*- Enable Interrupt and Switch in Supervisor Mode */ msr CPSR_c, #ARM_MODE_SVC Where ARM_MODE_SVC is set to 0x13, i.e. without 0x40 or 0x80. So if there's something wrong with the existing code, it should be fixed there rather than two copies of inline-asm in the USART and USB IRQ handler routines. So I do want to merge this very much, but I think it needs clean-up before it can be merged. I don't expect to have much time for this in the next couple of weeks, so I would be happy if either you or somebody else on the list could work on this. Regarding your comment about changing the USB protocol: This would lead to host / firmware version incompatibilities, and I'd like to avoid that if possible in any way. We already have the simtrace_hdr.flags structure member, which contains things like SIMTRACE_FLAG_ATR. I'm not sure if I understand your request fully, but why not simply add flags like: * First fragment of a fragmented APDU * More fragments to follow for this APDU This way a new APDU still has to start at the beginning of a USB transfer, but no changes to the simtrace_hdr are required.

After adding the length field, the host software can now follow the SIMTrace req_ctx, sufficiently enough for 4 minutes. Below is the serial port output from the debug port. Regarding the USBT() line, D is the hex address of the Data field. S is the sequence number (hex, short), L is the decimal length of the tot_len of the req_ctx, P is the number of req_ctx pending in USB_EP2 output queue.

I had not realized none of my commits are actually going anywhere so I have attached the patch files generated from git format-patch As I mentioned before, I found that changing the USB transfer header appears to be required to not have sync loss, but I have not committed that change since Harald wants to avoid making changes that will break the client software. As to the most recent change where I added code to extract the previous value of the PC register before entering the interrupt routines, it was because the System would sometimes appear to be frozen, where the heartbeat output no longer occurs, and it no longer accepts serial input (commands etc). After purchasing a buspirate, I isolated and confirmed that the processor is always running an instruction at the beginning of the default spurious interrupt handler. After replacing the interrupt handler, the system appears to recover, although it still encounters uart overrun and occasionally a parity error.

I don't have that much experience with the sam7s so I am not in the position to judge/verify your USB controller changes. The other part is that I really like commits that just fix one thing and have a clear description of that. I hope we can move forward in November with your patches. kind regards holger

New subject: Merging of Min Xu's patches

Dear Min Xu, Dear simtrace community, my sincere apologies for not getting around to merging your patches for what turned out to become more than a year. This is not intentional, but running a small company under constant overload left me with very little spare time and way too many neglected responsibilities towards the community projects :( I have finally taken some time to review, split/clean-up and merge the your patches. They are available in the 'minux-fixes' branch of openpcd.git, where the simtrace firmware is maitained for historical reasons. I didn't really (intend to) make any logical changes, but simply split it up in much smaller chunks, making sure that each patch really only addresses one issue, and also making sure that there are no unneeded whitespace changes in the change log. I have merged everything but the protocol change. For that, in order to have at least backwards compatibility from new host tools, we need to use the interfaceVersion as indicated by Peter Stuge earlier in this thread. I hope to be able to look at that before yet another year expires. If anyone wants to help out, I would appreciate patches for the following tasks: * forward-porting of min xu's protocol changes, but ** ensuring that the openpcd bulds still use the old protocol ** only simtrace builds should use the new protocol ** increment the bInterfaceVersion (for the simtrace builds only), once the change is made in the protocol * updating the simtrace host utility to check for bInterfaceVersion and provide code for both old and new protocol * ensure that changes to quantity and size of req_ctx apply only to simtrace builds, not to openpcd builds. Once all those issues are adressed, we can merge it into master. Please send a short message to this list if any of you is working on the above. p.s.: In other news, sysmocom has meanwhile produced and distributed close to 700 simtrace units. As it is a true open hardware project, we may not know how many others have built it themselves, using the schematics, bom and layout files provided. I would have never guessed that there are _that_ many people who have an interest in such an absolute 'niche' device. The only sad part is that despite that many users, we didn't get as many contributions. Neither on the wireshark dissector side, nor on the firmware side.

New subject: Merging of Min Xu's patches

Hi Harald Thank you so much for working on this. Since you have farmed out the formatting of the patches, and that I am less likely to have more time to work on this project, I am submitting all my git patches (11 of them so far) in a tgz format. I believe #1 to #6 were already sent in the past, #7 to #10 might have been sent to the mailing list, but I know #11 has not yet been sent to you or the mailing list. #1 to #10 were formatted as well as I could. #11 combined many changes and is not formatted as well. This is what my company currently use on all the board and we have not had any issues with it (GS5 / iPhone 6 / iPhone 5 etc). Maybe the person volunteering to split/format the changes will combine this in. Thank you so much. -----Original Message----- From: "Harald Welte" <laforge(a)gnumonks.org> Sent: Sunday, October 26, 2014 6:53am To: "Min Xu" <mxu(a)sanjole.com> Cc: simtrace(a)lists.osmocom.org Subject: Merging of Min Xu's patches Dear Min Xu, Dear simtrace community, my sincere apologies for not getting around to merging your patches for what turned out to become more than a year. This is not intentional, but running a small company under constant overload left me with very little spare time and way too many neglected responsibilities towards the community projects :( I have finally taken some time to review, split/clean-up and merge the your patches. They are available in the 'minux-fixes' branch of openpcd.git, where the simtrace firmware is maitained for historical reasons. I didn't really (intend to) make any logical changes, but simply split it up in much smaller chunks, making sure that each patch really only addresses one issue, and also making sure that there are no unneeded whitespace changes in the change log.
