Hi,
I will be developing custom board with iMX8M plus processor, i would like to understand what will be process of booting once i get fresh board after assembely.
I will be using NOR Flash and emmc5.1 in my custom board.
How i can load load my OS on NOR Flash or emmc5.1?
I would suggest you to order the EVK board first before you make your own board.
For the hardware design, you can download the i.MX 8M Plus Hardware Developer’s Guide and download the schematic of EVK for reference.
For the software, we have Linux Yocto BSP. You can download the documentation of BSP from here:
i.MX Yocto Project User’s Guide is talking about how to build the BSP.
i.MX Linux User’s Guide is talking about how to use it and how to program the images to the board. There is a tool called UUU used for programming the images to the board. Please read the user's guide for the details. And the UUU sample script can be found in the demo image (i.MX 8M Plus EVK).
