i.MX8M Mini boot from eMMC issue

KennyChu — Tue, 01 Dec 2020 11:59:12 GMT

Hi Supporter,

We build a yocto project by using MACHINE=imx8mmddr4evk.

Try to use UUU to flash imx-boot-imx8mmddr4evk-sd.bin-flash_ddr4_evk & imx-image-core-imx8mmddr4evk-20201201043011.rootfs.wic.

At end of log, it shows "MMC card init failed". Can you advise why this happened or how to fix it?

PS: Please check attached for boot config.

Can you use this command in shell to try again ?Put the uuu.exe into deploy folder.

uuu -b emmc_all imx-boot-imx8mmevk-sd.bin-flash_evk imx-image-full-imx8mmevk.rootfs.bz2

Best Regards

Hi Zhiming,

@Zhiming_Liu

Please help to check and advise.

We modify u-boot device tree to solve “MMC card init failed!” issue and UUU can flash image successfully now.
Switch boot mode to eMMC boot.
Power on/off DUT and it will hang up at u-boot.

You can use prebuilt images in our website for test.Normally, the boot process has no problem.You must set correct boot config like following picture.

The download command is "uuu -b emmc_all imx-boot-imx8mmevk-sd.bin-flash_evk imx-image-full-imx8mmevk-20200708060549.rootfs.bz2".
