Hello,
I just tried the demo image "imx-image-multimedia-imx8mpevk.wic" of L5.10.9 (SD card).
All is working.
Regards,
Yuri.
After booting from sd-card is done, I got the following output and uboot is not accepting any input from keyboard.

Please help me resolve this problem.
@kenizgandhi
Hello,
Looks like default U-boot configuration (network boot) takes place
in the case. Please try to stop U-boot right after it starts and configure
U-boot environment for SD boot.
Regards,
Yuri.
Hello,
I am unable to stop u-boot as it doesn’t accept any input from keyboard. That’s the main issue.
@kenizgandhi
Hello,
I just tried the demo image "imx-image-multimedia-imx8mpevk.wic" of L5.10.9 (SD card).
All is working.
Regards,
Yuri.
I think i changed the emmc device in uboot after that it doesnt boot. Can you please tell to get back to the booting process?
@kenizgandhi
Hello,
You may try to transfer the Linux demo image to Your board.
https://www.nxp.com/webapp/Download?colCode=L5.10.9_1.0.0_MX8MP&appType=license
Use instructions of the User's Guide.
https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf
Summary Page:
Note: The i.MX 8M Plus EVK board has one TF card slot. This slot uses the USDHC2 controller.
So, it is possible to prepare /write boot SD card, using demo .wic file.

Yuri.
