Hi all, are there tags for the v1.0p hardware and other prototypes? I don't see them with git tag -l. holger

This patch should fix the crash from simtrace app when SIMtrace hardware is unpluged from usb or when it is reseted. This feature was proposed on simtrace workshop on ccc camp.

SIMtrace poster for the Camp?
by Harald Welte 05 Aug '11

05 Aug '11

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 02 Aug '11

02 Aug '11

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...
