Harald Welte laforge at gnumonks.orgHi 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:

After that, the new firmware has been programmed into your SIMtrace and
you can immediately use it again (no reset/re-plug/... needed)

Harald
