you can follow the i.MX6 U-Boot guide to generate a new U-Boot for imx6 SOM.
The quick test can be:
1- install general i.MX6 image from Solidrun web (sr-imx6-debian-buster-20220731-cli.img.xz) & uncompress & flash it on SD Card
2- override the bootloader (U-Boot & SPL) of the SD card using the commands below:
| Code Block |
|---|
dd if=SPL of=/dev/sdX bs=1k seek=1 conv=sync
dd if=u-boot.img of=/dev/sdX bs=1k seek=69 conv=sync |
Attached here is a pre-built U-Boot and SPL with the above changes applied.
