ok, tell me how did you program the image to your board, what command do you use, and what image version do you use? because I test latest version, couldn't reproduce your issue on my imx8MM board
Hello, the image above I am using mfgtools-uuu_1.2.91 and visual studio 2019
I am currently using uuu.exe. I can write rootfs.sdcard to uboot, image and rootfs to emmc, but how to write uboot, image and rootfs to emmc separately. Because my git clone uboot and image source have been compiled. But don't know how to write separately
if you need to program uboot and kernel to EMMC, you can refer to the example_kernel_emmc.uuu which under folder named samples, put your own demo image name in the uuu file, then use the command like "uuu.exe example_kernel_emmc.uuu"
