Alexander Pasihov

Part Number: TMS320F28374D

Hello ,

I'm looking for project (code) example that implements SW (firmware) upgrade/boot on F2837xD.

I have to the following questions :

1. How store new code in the flash (it's new version of SW) - where new code is loaded from host using SCI-C (not A) , How flash it to memory byte-byte? - code example

3. How change entry point in boot loader controller (F2837xD) in purpose to start upgraded version ? -code example

Thx,

AlexP

Dear Baskaran,
Thank you very much for your assistance,
It helped me to understand the mechanics of bootloader.

Now I have an additional question (I new F2837xD user) : If code (out.file) is sent in Textronix Extended Format , any library may be used in purpose to decode one record and/or calculate check sum? Maybe any other format is more applicable ?

Sincerely,
AlexP
