TMS320F280049: limitation of stack pointer for ucos

Strong ZHANG

Part Number: TMS320F280049

Tool/software:

Hi Expert,

For freeRTOS, the stack pointer should be limited to access only range 0x0000-0xFFFF.

my customer are using ucos, is it also have this limitation for stack pointer?

Hi,

Yes, the same limitation applies. The C28x CPU stack pointer (SP) has only 16 bits, therefore it can only access the lower 64K of data space.

Thanks,

Arnav
