FreeMaster don't display the value

[peigong]

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
