RT1064 flashloader source code doc for developer

John_Lin — Fri, 27 May 2022 06:47:50 GMT

Hi,

I have asked a question about the external flash programming, the answer is helpful:
https://community.nxp.com/t5/i-MX-RT/RT1064-external-SPI-flash-programming/td-p/1464372

But I still have a question, simply speaking I want to modify the source code of flashloader to make it support the external FlexSPI flash programming.

My question is: Is there any documentation for the developer to understand the source code of flashloader, and guide the developer to modify the source code.

Thanks!

John

Hi @John_Lin ,

I'm sorry but there isn't documents or guides for the RT bootloader. I think you can refer to the MCUboot reference manual because RT's bootloader is update from MCUboot. You'll find they are similar. They share same PC tools, for example, the blhost.

For the FlexSPI1 demo, you can refer to the RT1060 SDK.

Jing
