Hi,
I am using following .CMD code for memory allocation for C2000 TMS320F28035 microcontroller and I am facing problem of less available RAM memory for my program code. I tried to increase progRAM by reducing dataRAM with same size, but it gives error. Please help me by modifying some statements of following code to increase memory size for program RAM. Or suggest me literature to achieve this task.
Thanks,
Rupesh
