Hi all!
Just in time before OsmoDevCon, I managed to releaes a new version of the SIMtrace firmware.
The list of changes is quite extensive and should address a number of the reliability problems that people have experienced.
The changes include: * don't activate pass-through and LDO supply for the sim card at the same time, leading in power leaking from simtrace into phones * fix a watchdog timer misconfiguration leading to occasional watchdog resets * fix detection of sim insert/removal * better VCC_PHONE detection * reduce the amount of debug logging on the serial console and replace it by statistics (count of bytes, overruns, parity errors, etc) * statistics can be read from the UART by pressing 't'. * no longer crash the simtrace firmware if no simtrace host program is running
Using this v0.5 firmware and a pretty aggressiv program causing lots of traffic (hunz' simdump) on a cm3121 reader at card Fi(9) Di(4) ratio 64 didn't cause any lost bytes or SIMtrace resets for me anymore.
Any feedback is appreciated.
Regards, Harald
