Hi NXP,
Our board has done DDR tools and verify with SDK imx-5.10.9, and it flash with dd command. However , it cannot boot successfully by flashing with dd command for SDK imx-5.10.72-2.2.0 and you told me to flash by uuu.
https://community.nxp.com/t5/i-MX-Processors/i-MX8M-Plus-boot-from-sdcard-fail/m-p/1421722#M187673
So I test with EVK first.
I flash release image dwonload from NXP successfully with uuu to EVK and sdcard on EVK.
Then I repo SDK imx-5.10.72-2.2.0, build full image, flash built files (imx-boot-imx8mpevk-sd.bin-flash_evk and imx-image-full-imx8mpevk.wic.bz2) with uuu to EVK successfully.
Now I merge what we modified for DDR of u-boot before in SDK imx-5.10.72-2.2.0.

Build new image and try to flash new built files in our board.
It stuck after flashing bootloader.

u-boot=>
In our hw design, USB1 connects to hub by default.
If we want to use uuu, hw engineer will disconnect the connection of USB1_DP and USB2_DP and make it connect to a connector to normal usb 2.0 port. (remove R225 and R226, add R156 and R157) Remain else USB1 pins connecting to hub.
It is OK for DDR tool.
But is it OK for uuu download? Does uuu download need usb 3.0? Or how can I modify uboot for this usb design?
Best Regards,
Sophie
