Hi,
I use sbl and change the dts
bootargs = "console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000"
==>bootargs = "console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmcblk1p2 root rootfstype=ext4 rootwait"
it can boot to linux from SD card in 7200_EVM
But when I use the board without EMMC made by myself, the kernel reports the following error

I found I found the kernel stuck in the board-support/linux-5.10.41+gitAUTOINC+4c2eade9f7-g4c2eade9fe/init/do_mounts.c Line 623
while(driver_probe_done() != 0 || (ROOT_DEV = name_to_dev_t(saved_root_name)) == 0) { msleep(5); }
When I comment out this code, The kernel is stuck due to lack of MMC
So, how can I start up linux from SD card without EMMC?
thanks.
