Implementing a bootloader Issue MIMXRT1064CVL5B

kksakthi — Wed, 22 Feb 2023 15:56:23 GMT

I am implementing a bootloader for IMX.RT1064. I'm using ROM API to erase and program the new firmware. I'm trying to erase the section after the bootloader and it is not working. When I tried erasing the sector that doesn't has the program, the erase API worked. Whether the sectors with the program is protected?

Our goal is to implement a bootloader that can read the firmware from external SPI flash and program to the internal flash.

Hi,

First of all, sorry for the later reply.

Please refer attached example code about ROM API usage.

Wish it helps.

best regards,

Hi

See the following for off-the-sheft loaders for the 1064:
- https://www.utasker.com/iMX/RT1064.html
- https://www.utasker.com/iMX/developers.html

Supporting various methods (USB, Ethernet, SD card, Memory stick, external SPI) and allowing operation in Xip, XiP-BEE encrypted, RAM and SDRAM (with optional AES256 storage in Flash).
Stable, fully documented and industrial proven solution.
