What do you think would be the maximum speed the current HW (v1.1) could handle (if tuned a little bit ;-) ?
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?
