Part Number: TMS320C6457

Tool/software: TI-RTOS

I load the processor with EMIF. It is my bootloader.

I'm download the program from Ethernet to DDR.

I forbid all interrupts and copy program from DDR to internal RAM (to 0x800000).

Jump to cinit. The CPU is not work. Program do not jump to "main" function.

How to copy a program from DDR to internal memory and restart the program?

Please share which SDK are you using?

I've notified the RTOS team. They will post their feedback directly here.

Note that answers may be delayed due to holidays.

I solved the problem. Had to be before the copy of the DDR to disable all interrupts. Now everything works.
