Hello @ThinhNguyen_FE 

I guess you are using i.MX8MP EVK, so, please download a BSP from Embedded Linux for i.MX (you can try with L6.1.36_2.1.0_MX8MP) and please load the downloaded BSP to the board using UUU tool. 

For download the BSP with UUU tool, please follow the below steps:

1. Put board in Serial Download mode changing SW1101 [D1-D4]

Connect trough USB your PC and the EVK.

Turn on the board.

To test if the board is in serial download mode you can write command:

If using Linux

$ sudo uuu -lsusb

If using Windows

> uuu -lsusb

And the logs should describe the hardware that is connected to your PC, in this case i.MX8MP.

2. Assuming the SDcard is connected to EVK, go to the directory where you downloaded the BSP and run the below command:

If using Linux

$ sudo uuu -b sd_all imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk imx-image-full-imx8mpevk.wic

If using Windows

> uuu -b sd_all imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk imx-image-full-imx8mpevk.wic

That command will download the image in the SDcard of the i.MX8MP.

3.When the download ends, put the board to boot with SD:

Then it can boot successfully.

Please let me know if any problem.

Best regards!
