Problems encountered during system startup through EMMC

My device is MPSoC. After I set the system to start from EMMC through petalinux, I downloaded both boot and rootfs into EMMC respectively, and added the command to start rootfs from EMMC partition in boot partition. However, the following problems still occur: when SD is not plugged in, rootfs system cannot start. Rootfs system will start only after SD card is plugged in, and Started from SD

 

Here are the boot commands I added to the boot partition :

bootargs=console=ttyPS0,115200 earlycon clk_ignore_unused root=/dev/mmcblk0p2 rw rootwait earlyprintk

Re: Problems encountered during system startup through EMMC

Hi @shiyangcool ,

Can you post the boot logs and also can you try accessing eMMC from u-boot using "mmc info" commands

Thanks,
