TMS320C6713B: Code execution from flash directly

kowalski

Part Number: TMS320C6713B

Hi,

I am working on c6713 processor. its kind of old chap. the code runs from IRAM (internal RAM). On boot, the processor copies 1k of code from CE0 region (NOR flash is mapped here) to IRAM. The remaining code needs to be copied using a bootloader. My question is it possible to run code directly from flash (mapped on CE0) rather than copying the code to internal RAM (IRAM) and then running it from IRAM in c6000 family?

Kind Regards,

Ijaz

Hello,

That should be possible. Please see if the following collateral helps resolve your issue:

Hi Sahin,

Thanks for your kind reply but i guess the links you provided mainly focus on how to BURN flash. That's not an issue in my case - what happens after burning the flash at boot time, that's what i am concern about. I want to run code from flash. by default we burn the code in flash and load it into internal ram via bootloader. I want the code to run directly from the flash.

Kind Regards,

Hello,

I'm looping in our bootloader expert to help with this.

We don`t support Execute in place (XIP) that allows this DSP to run code directly from Flash on these devices. The bootloader always copies code into device memory for execution.
