HI
I'm learning the trace of ARM cortex_m3
after run the trace-test, i check the inside signal of TPIU and i found the format data is different from the ITM data
in the picture the fifo1_data_i is from ITM and its a serials of packets the fromat_data is the final valid data output
for example the formater add a b3 in front of 17 and change the 3 to 2 (..c0 15 3 dd... to ....c0 15 2 dd ...)
i have read the ARMv7 reference manual and the manual just tell me the packet protocol. but therer is nothing about the format of a packets stream
