1.i download imx8mp code,use DISTRO=fsl-imx-wayland MACHINE=imx8mp-lpddr4-evk source imx-setup-release.sh -b buildwayland1

2.after build,i get imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk,flash sd card,board run normal.

3.dd if=imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk,of=/dev/mmcblk2 bs=1k seek=32,boot_mode switch to emmc boot,but emmc can not boot.

Hi @jimmyhua!

Thank you for contacting NXP Support!

The file "imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk" works for MMC and SD cards.

Please try to use the UUU tool to flash the files to your board.

Best Regards!

Hi @jimmyhua!

What board are you using DDR4 or LPDDR4?

If you are trying to burn the incorrect image the uuu never flash the board.

Please try with the DDR4 image.

Best Regards!

1. It is very clear for the log, this board has different hardware to NXP i.MX8MP EVK. At least the usb has no typeC design. Should change the u-boot device tree to satisfy the hardware.

tcpc_init: Can't find device id=0x50

setup_typec: tcpc port2 init failed, err=-19

tcpc_init: Can't find device id=0x50 setup_typec: tcpc port1 init failed, err=-19

USB init failed: -22

2. If the ddr type(DDR4/LPDDR4) is wrong, could not run till u-boot console.
