Dear Sir or Madam: I've bought two simtrace development boards two months
ago in order to research the communication between the SIM-card and the mobile
phone. However, recently when I need to analyse the packet which contains CK
and IK, I sadly found that the packet was not captured every time. Mostly it
returns as a malformed packet in the wireshark, which blocks my future
studying. I read the user manual and it says that for some high speed cards the
firmware can lose bytes, and to solve that we can reduce the size of the
buffer. So I'm writing to ask the specific steps to reduce the buffer
and recompile the firmware, and I've tried by myself but I couldn't find a
proper toolchain which includes a GCC but not an EABI. I'm looking forward to
your reply. Best wishes!
Yours, sincerely
Luna-Qi
