Dear,

My application is EV Air Conditioner, I will use TMS320F28069. I have use TI TMS320F28335, and I find TMS320F28069 has a extra RAM. The detail is as below.

     0x010000~0x11FFF   L7 DPSARAM (8K x 16)(0-Wait, DMA RAM 2)

     0x012000~0x13FFF   L8 DPSARAM (8K x 16)(0-Wait, DMA RAM 3)

As I know, the RAM of 0x010000~0x13FFF can't be used as Stack, because the pointer is only 16bit.

But as global variables, is there any limit?We have meet many problem. Could you kindly help check and give some advice? Thx
