Original question:

Memory allocation on TMS320F28035

TMS320F28035: TMS320F28035 increasing stack size

Part Number: TMS320F28035

I am developing a code for TMS320F28035.  Currently working on the F28035 Piccolo Experimenter's Kit.  I changed the stack size to 0x500 and  updated the comand file with following lines  - 

      .stack              : >> RAMM1 | RAMM0,   PAGE = 1

However the linker throws an error

split run placement for this section is not permitted
.stack : >> RAMM1 | RAMM0, PAGE = 1
"../F28035.cmd", line 168: error: program will not fit into available memory,

Does this mean the stack size cannot be increased beyond 0x400?

Regards,

Ramesh

    Hi Ramesh,

    The linker cannot split the .stack section. Since RAMM0 and RAMM1 are continuous, you can resolve the issue by combining these 2 blocks to form a larger memory block.

    Eg:

    //RAMM0 : origin = 0x00000128, length = 0x000002D8
    //RAMM1 : origin = 0x00000400, length = 0x000003F8

    RAMM01 : origin = 128, length = 6D0

    .stack : > RAMM01

    Regards,
