i.MX8MP - Boot via u-Boot - binary structure

Heiko_Patz — Thu, 23 Nov 2023 09:09:17 GMT

Hello,

I want to understand how the resulting boot binary must be combined that the i.MX8MP will boot properly by u-Boot bootloader.

I found already some documentation which are addressing this topic (i.MX Linux User's Guide, AN1403: Fast Boot on i.MX8M and i.MX9 using Falcon Mode and Kernel Optimizations) but I did not find a documentation how the SPL+ATF+u-Boot must be fit together so that is will run.

Yes, we can use imx-mkimage, but where is the documenation what has to be done?

Is there already some documentation how the three parts must be combined?

Thanks

Hi @Heiko_Patz

As I know, there is no such documentation. Would suggest to refer to (GitHub - nxp-imx/imx-mkimage: i.MX Mkimage Bootloader Tool) to get more information.

Harvey
