Hi,
just from the expectation: The SAM7 should support all modes of ISO 7816-3 so
I would expect that the SIMtrace works with all of them as well. My debug
proposal would be:
Topic:
Find out where the byte(s) is lost.
How:
I am not sure if the debug uart code is IRQ driven and if it has a rather long
queue.. but... I would start by dumping every received byte to the other UART
and compare the results.
Reasoning:
This should isolate the problem to be either on the USART (receiving data
properly) or in our USB code.
Before one starts:
Are you sure that the data is missing in the 'URB', in contrast to the host
utility losing them when splitting APDUs?
