Hi, All, When I use the freemaster , it seems that the communication between PC and MCU is correct, but On the PC freemaster interface, the value don't displayed but only the "?".
Req: 2B 22 02 3C 04 2D
Rep: 2B 22 04 88 13 00 00 78
Is there any problem with the data frame or the freemaster setting?
Thanks
Hello,
you are showing two requests (2b,22 = read memory), not the request and response. Without this, I cannot tell what exactly is wrong.
Typically, the ? is displayed when FreeMASTER cannot read the data because of FMSTR_TSA_SAFETY is enabled and FreeMASTER tries to access a "forbidden" variable which is not listed in any TSA table. If you use TSA_SAFETY, try to disable it first.
If this is a different issue, please send us the real log entry with all details of the request and response on the line.
Regards,
Michal
