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.
