Hi, I think I found a small hardware bug while fixing the v1.0p boards (adding a 100nF capacitor near the LDO pin 4). When I want to put the SAM7S in SAM-BA mode (shorting TEST and 3.3V pins), it does not work, even after waiting a lot of time. The 2 LEDs are on, and when I touch PA0 (pin 48 on the right upper corner of the SAM7S, near the "A") with a piece of metal, the LEDs switch off and putting into SAM-BA mode works. maybe PA0 needs to be low/up but it is not connected and probably floating. The solution is easy, but should we correct that for the next version (if it is a real bug)? Also, simtrace seems to load sam_ba module, which I have to remove so I can use sam7util multiple times: sudo rmmod cdc_acm && sudo rmmod sam_ba && sudo ./sam7 --exec set_clock --exec unlock_regions --exec "flash ../openpcd/firmware/main_simtrace.samba" thanks, kevin

'no simcard' bug / SIMtrace firmware update

by Harald Welte

Hi all, I have meanwhile solved the first half of the bug that was causing a lot of problems during the CCC Camp 2011. In git commit fa7297b93f4187bce9439bb676874815f66d8f21 to openpcd.git, I have made the following changes: * make sure SIMtrace remains completely passive even in case of (alleged) parity errors * prevent an IRQ storm by properly clearing error flags in the USART, which have lead to a watchdog triggered reset which in turn caused a USB disconnect So right now, you should not see the "No SIM card" or "SIM card error" in the display of your phone, no matter what phone / simcard is used. However, the data logged by SIMtrace still is incorrect in those cases. I hope to release a fix for that soon. The updated 'main_simtrace.bin' firmware is attached to this mail. You can install it by using "dfu-util -d 16c0:0762 -a0 -D ./main_simtrace.bin -R" which should produce something like: ======= dfu-util - (C) 2005-2008 by Weston Schmidt, Harald Welte and OpenMoko Inc.

TST PIN and SIMtrace Schematic question

by Holger Hans Peter Freyther

Hi all, I have a stupid schematic question. I read section 6.2 of the SAM7 datasheet (as in the git tree) and it mentions that besides TST high also PA0, PA1 and PA2 needs to be high, and PA0, PA1 should not be low as this leads to unpredictable results. So I wonder about the following: - PA0 is not connected, default state should be high - PA1 is connected with a trace that leads to PA6 - PA2 is connected with a trace that leads to PA4 will PA4, PA6 work like a pull down (I am not sure of Table 10-3)? cheers holger

Connecting the FTDI cable

by Stefan Petersen

Hello! I skimmed over the schematic and noticed that the power output from the FTDI cable is connected directly to the 3.3V line. In my experience the output from the FTDI cable is 5V even though it is the 3.3V version. I have actually fried some designs due to this. I'm not 100% sure about this, but my tips is to check it before you connect it. Best regards, /Stefan

SIMtrace usermanual

by Holger Hans Peter Freyther

Hi all, there is a doc/ directory in the simtrace source and the documentation is done with docbook. The result of the document can be seen here[1]. It is still missing proof reading, sections on building the patched wireshark, building the firmware and more content. comments welcome holger [1] http://bb.osmocom.org/trac/attachment/wiki/SIMtrace/usermanual.pdf

[PATCH] fix simtrace crash when unpluging usb

SIMtrace poster for the Camp?

by Harald Welte

Hi all! I know it's a bit on short hand notice now, but maybe somebody is interested in doing a SIMtrace poster that we can put up in the Radio Village at the CCC Camp. It doesn't have to be super-fancy / super-glossy, just something that draws a bit of attention that SIMtrace is present there, and what it is. Some ideas for bullet points: * trace communication between phone and SIM * man-in-the-middle * analyze + debug SIM Toolkit * analyze proactive SIM * SIM firewall * SIM card emulation Printing the poster shouldn't be a problem, if somebody just wants to do the design as SVG. Thanks in advance if anyone finds time for doing it... -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

at91lib / multi-configuration device

by Harald Welte

Hi! It took me quite a long time to fix all the bugs I discovered in the at91lib USB stack, particularly in the CCID code. The next problem was that the core USB code could not deal wit devices that implement multiple configurations correctly. But finally I got it to work. There is now a multi-configuration project which is part of the git://git.gnumonks.org/at91work.git git repository. Curious people can type 'make' in the usb-device-multi-project sub-directory, which will render a usb-device-multi-project-simtrace-at91sam7s128-flash_dfu.bin file. That file can be flashed into the simtrace using dfu-util like this: dfu-util -a0 -D ./usb-device-multi-project-simtrace-at91sam7s128-flash_dfu.bin -R The firmware doesn't really do anything yet, but it should show up on USB as a device with three configurations (one for sniffer, one for reader and one for MITM). I've started to port over my sniffer code from the openpcd repository, but I'm not sure when I'll have time to finish it. Maybe still before the camp, we'll see...
