TMS320F28379D: Flash API

electrocc

Part Number: TMS320F28379D

Hi,

I'm working currently on a software to reprogram my microcontroller with a file on a SD card (I simply convert .out file in a HEX file using hex2000.exe).

The goal of my software is to:

- read the .HEX file to determine its size.
- erase all FLASH sectors
- Write in Flash (from sector A) values corresponding to the program.

I manage to perform all the steps, but when I'm writing in the Flash, software stops at the address 0x8F4B2 (sector E).
However, the program is not yet entirely written (see attachment)

I've read the https://processors.wiki.ti.com/index.php/C2000_Flash_FAQ, and issue is not due to 128-bit aligned memory i think.

Thanks for your answer.

Hi,

What error did you get from Flash API when it failed?

Hope you are executing Flash API from RAM.

Thanks and regards,

Hi Vamsi,

I don't understand why but this morning when I reboot the Control Card, it worked.

After reprogramming all my FLASH, do I need to reset the Core? If yes, how must I do?

Thanks for your help.

Hi,

Glad it worked.

Do you mean to say that Flash programming worked after the reset? OR the programmed application worked fine?

Thanks and regards,

Vamsi

Hi Vamsi,

No I just mean that I've succeed to programm all the Flash sectors after erasing them.

But after, I want to reset the core to boot on the Flash.

How must I do?

Thank you

Hi Vamsi,

One question again : I'm currently using an USB cable to program my chip.

But after switching off / on power supply, I want to run program which is in the Flash.
Because if I change switch on A:SW to boot on Flash, I can't use xds100v2 emulator anymore?

How can I proceed?

Regards

Hi,

If you want to reset, you can use watchdog reset to accomplish that. Please check TRM for the details. Let us know if you have any specific question.

Since the original issue discussed in this post is resolved, I would suggest to open a new thread for your further queries so that we can assign an appropriate expert to help you better.

Thanks and regards,
