Hi,
I am trying to debug an application for the F28377D, including code to run on the CLA. It all used to work fine a few weeks ago but I had to migrate my project to Mac OS and I am now mapping some of the F28377D code to Flash.
My issue: I cannot seem to load properly the CLA program. When I attempt to load symbols the debugger point to 0x00000000. I checked the .map file and it seems that the Cla1Prog code is in Flash and is properly copied to RAM. I really have no clue how to fix this. Any idea?
Here's my .cmd file:
#ifdef CLA_C
// Define a size for the CLA scratchpad area that will be used
// by the CLA compiler for local symbols and temps
// Also force references to the special symbols that mark the
// scratchpad are.
CLA_SCRATCHPAD_SIZE = 0x200;
--undef_sym=__cla_scratchpad_end
--undef_sym=__cla_scratchpad_start
#endif //CLA_C
