Record function error in 3.1.2.4 when freemaster connect 16bits RAM CPU

Hi:

I found record function run error in Ver 3.1.2.4 when freemaster connect 16bits RAM CPU, The 3.0 version has the same fault, but the 1.4 version runs normally. I checked the code and the problem is located：freemaster software does not handle the bit width, so the addr calculation error in _FMSTR_ReadMem function in the 16bit memory causes the recorder upload error (_FMSTR_ReadMem function will be execute after the data recorder function run over). addr parameter in _FMSTR_ReadMem function accumulate should be divide FMSTR_CFG_BUS_WIDTH.

Hello,

thank you for your bugreport, we will make sure to retes and implement the fix that you propose.

Can you tell what 16bit-RAM platform do you use? Is it one of the older DSC devices?

Thank you,
Michal

Hi, there

Thank you for your reply.

My platform is TMS320F28377D, I migrated the new version communication firmware on this CPU and use Ver-3.1.2.4.

The old version communication firmware works well when I use Ver-1.4 freemaster, but go wrong in Ver 3.0 and the new version communication firmware with Ver-3.1.2.4 has the same fault.

The error is shown in the picture above.

Fault maybe like this: Freemaster will upload the record data when recorder function triggered. For example, buf[1000] stores the recorded data, and 1000 pieces of data need to be uploaded. In 8-bit memory mode, a maximum of 240 data is transferred each time, and the address increases by 240, but in 16-bit memory mode, the address should increase by 120.

Thank you.
