IMX8MP LPDDR4 2GB

[petertseng]

Hi

I'm currently using i.MX Linux Yocto BSP (mickledore-6.1.22-2.0.0)

And we have 2GB LPDDR4 on our board.

The following error occurs:

Hi, @petertseng 

you need to use the DDR Tool generate the new timing.c file, and replace the orign timing.c file, and re-compile your uboot. then boot your board.
