Hi,
I see earlier in the archives that reducing the buffer size in the firmware will resolve
this. Hasn't this already been done though in new releases of the firmware? As I have
pulled the latest version from the openpcd git repo and built it. If not what have people
reduced the buffer size to? And has it had any fixes?

The closest are the patches that Min Xu sent. They require some
clean-ups and review (specially the code changing the interrupt
handling).

Hi Holger
To give you an update. As far as I can tell, the changes I have submitted,
with the addition of a change (on my local system) where the USB protocol
has been modified to remove USB overrun, is stable so I can monitor iPhone
5S as well as Galaxy S4 continuously. If anyone asks, I would be happy to
send them the USB protocol changes. However, it will be INCOMPATIBLE with
earlier firmware based SIMTrace boards.
I am making changes to the host program (on Windows) to monitor multiple
SIMTrace devices, and am interested to know if anyone else is working on
something similar.
Best Regards

Hi min,
How do you mean that they would be incompatible with early firmware based tracers?
I'd be interested in using your firmware if you were to make it available, I'm
also working on a more user friendly host software.
Kind regards

It's incompatible because due to the way the USB peripheral transfer the
data out to the host, there is NO mechanism to indicate exactly where the
next USB transaction should start. Therefore, when the data is flowing
very fast, every 64 byte (the bus width) write to the USB peripheral will
be concatenated together, resulting in the host read to combine multiple
req_ctx buffers.
The way I solved it is by adding fields to the simtrace_hdr structure:
(the + indicates the new fields). This allows me on the host to keep track
if / where a new req_ctx begins in the received usb data.
struct simtrace_hdr {
u_int8_t cmd;
u_int8_t flags;
u_int8_t res[2];
+ u_int16_t seq_num;
+ u_int16_t offset;
+ u_int16_t tot_len;
u_int8_t data[0];
} __attribute__ ((packed));
Since the laptop that I was using to create multiple commits is not
available at the moment, I am attaching the git diff from the
repository (instead of from my last commits in previous email). Meaning
this is a single diff file.
For the host software, the basic change in the process_usb_msg function.
My implementation is a naive implementation using a much larger buffer to
copy data to, where if a req_ctx is split across multiple usb transfers, it
will join those fragments then process:
struct simtrace_hdr {
u_int8_t cmd;
u_int8_t flags;
u_int8_t res[2];
u_int16_t seq_num;
u_int16_t offset;
u_int16_t tot_len;
u_int8_t data[0];
} /* __attribute__ ((packed)) */;
static char usb_buffer[66000];
static unsigned usb_remainder = 0;
int process_usb_msg(uint8_t *buf, int len) {

That does make sense to me since I had issues where before I changed the
usb header, the host was sometimes merging multiple req_ctx into a single
usb read.
I am attaching a tar.gz file containing all my changes as separate git
commits / format-patches and hopefully it will get committed to the
repository. This includes the latest change to the usb header as well as a
change (as Peter suggested) to the bDeviceProtocol in
usb_descriptors_openpcd.h, setting the new value to 0.

Hi Dean
I believe that you are seeing incomplete or partial (maybe even) ATRs. I
believe I experienced something similar when I see parity error in the
debug messages (from the debug port). The first byte of the ATR must be 3F
or 3B. I believe the firmware code I currently have should NOT break and
ATR into multiple segments. Besides, ATRs are transmitted in a single
frame, so there would not be an idle time to push out the partial ATR into
the USB transmit buffer.
So I believe you are having similar problem that I experienced when the
ribbon cable is twisted, or bent close together like a U (which might have
caused interference... )
Try get a serial cable plugged into the simtrace board, and capture the
debug output to see if parity error were seen.
Best regards

Hi Min,
I've just been using the new firmware with a different type of sim card
and noticed that the ATR is scrambled, at least for the header of the ATR.
The ATR is the same length as the one I had great success with. The cards
are running at the same speed according to the ATRs however the new card
seems to send it's ATR over 3 commands not just one. Whats also interesting
is the ATR scrambling is different. Here is an example with the Simtrace
Header attached:
01 01 01 01 01 00 00 00 1a 00 e7 9a 03 1f c7 80 31 00 00 00 00 00 00 00 00
00
01 00 01 01 02 00 00 00 0f 00 00 00 00 00 00
01 00 01 01 03 00 00 00 12 00 00 00 00 00 00 00 00 00
And the ATR should look like:
3B 9F 96 80 1F C7 80 31 00 00 00 00 00 00 00 00 00 00 00 00 00 00
And with the same card from the same company I got:
01 01 01 01 01 00 00 00 16 00 9f 96 80 1f c7 80 31 00 00 00 00 00
01 00 01 01 02 00 00 00 13 00 67 42 70 02 10 00 00 01 f9
01 00 01 01 03 00 00 00 12 00 ff 10 96 79 ff 10 96 79
With the card I had success with I got the following input in:
01 01 01 01 01 00 00 00 20 00 3b 9f 96 80 1f c7 80 31 00 00 00 00 00 00 00
00 00 00 00 00 00 00
And the ATR looks like:
3b 9f 96 80 1f c7 80 31 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Any ideas where these errors are coming from in the firmware. I notice
that the lengths in the failed are equal to 3B which is the start of the
ATR if thats of any help. The tests were done with the same phone connected
to the tracer just swapping the sim cards.

usb header, the host was sometimes merging multiple req_ctx into a single
usb read.
I am attaching a tar.gz file containing all my changes as separate git
commits / format-patches and hopefully it will get committed to the
repository. This includes the latest change to the usb header as well as a
change (as Peter suggested) to the bDeviceProtocol in
usb_descriptors_openpcd.h, setting the new value to 0.

Hi Dean
As far as I know, I made no changes to modify the usart/iso7816
communication parameters. I have seen parity errors like this, and got
improved result when I can make sure the flat ribbon cable is not folded
over on itself. The parity error is reported by the usart peripheral,
which is supposed to provide 1 character at a time to the main software
code. I will check the changes again.

Sorry for the slow response had a lot of work on. I do not have a debug

have tried it in all orientations to see if this was the case.
I've also not been able to apply your patches correctly to work out where

I believe that you are seeing incomplete or partial (maybe even) ATRs.
I believe I experienced something similar when I see parity error in the
debug messages (from the debug port). The first byte of the ATR must be 3F
or 3B. I believe the firmware code I currently have should NOT break and
ATR into multiple segments. Besides, ATRs are transmitted in a single
frame, so there would not be an idle time to push out the partial ATR into
the USB transmit buffer.
So I believe you are having similar problem that I experienced when the
ribbon cable is twisted, or bent close together like a U (which might have
caused interference... )
Try get a serial cable plugged into the simtrace board, and capture the
debug output to see if parity error were seen.

Hi Min,
I've just been using the new firmware with a different type of sim card
and noticed that the ATR is scrambled, at least for the header of the ATR.
The ATR is the same length as the one I had great success with. The cards
are running at the same speed according to the ATRs however the new card
seems to send it's ATR over 3 commands not just one. Whats also interesting
is the ATR scrambling is different. Here is an example with the Simtrace
Header attached:
01 01 01 01 01 00 00 00 1a 00 e7 9a 03 1f c7 80 31 00 00 00 00 00 00 00
00 00
01 00 01 01 02 00 00 00 0f 00 00 00 00 00 00
01 00 01 01 03 00 00 00 12 00 00 00 00 00 00 00 00 00
And the ATR should look like:
3B 9F 96 80 1F C7 80 31 00 00 00 00 00 00 00 00 00 00 00 00 00 00
And with the same card from the same company I got:
01 01 01 01 01 00 00 00 16 00 9f 96 80 1f c7 80 31 00 00 00 00 00
01 00 01 01 02 00 00 00 13 00 67 42 70 02 10 00 00 01 f9
01 00 01 01 03 00 00 00 12 00 ff 10 96 79 ff 10 96 79
With the card I had success with I got the following input in:
01 01 01 01 01 00 00 00 20 00 3b 9f 96 80 1f c7 80 31 00 00 00 00 00 00
00 00 00 00 00 00 00 00
And the ATR looks like:
3b 9f 96 80 1f c7 80 31 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Any ideas where these errors are coming from in the firmware. I notice
that the lengths in the failed are equal to 3B which is the start of the
ATR if thats of any help. The tests were done with the same phone connected
to the tracer just swapping the sim cards.

Hi,
I was looking for a fix to the problem, I am not technical enough to
understand all what you say. But is there a howto or anything i can use, so
I can implement your solution whith my limited technical knowledge?
Thanks in advance!

Hi Dean
I recently worked on the firmware again and believe I have fixed the issues
with the parity errors (at least for my SGS 2 and SGS 4 with ATT 4G/LTE
cards)
Can you try the attached firmware and let me know your results?
Thanks
