Firmware upgrade via SPI

kimdukyu · ‎07-21-2022

Hi,

My MCU is MPC5746C.

I would like to implement a function that the host can upgrade the MCU firmware via SPI bus.

Could you give me some ideas or any demo codes for my reference?

Hi,

We provide this application note:

https://www.nxp.com/docs/en/application-note-software/AN5319SW.zip

It is simple serial bootloader which can be used as a starting point to develop own solution for your SPI version. I believe it will help to understand the basic principles.

Thanks for the reply.
I want to know how to compile.
And if you have MPC5746C bootloader example program, can you tell me?

Hi,

projects are done in GreenHills so either you need to have that IDE or you need to migrate to IDE you have.
Do not have MPC5746C bootloader example program.
