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.
