Why did the linux kernel boot stop at mmc0?
I have compiled tf-a, optee, kernel and u-boot inside STM32CubeIDE.
I have copy over the uImage from the linux build/arch/arm/boot/ and the .dtb file as well. They have been copied over to st-image-bootfs-openstlinux-weston-stm32mp1.ext4 file. I'm only changing the st-image-bootfs-openstlinux-weston-stm32mp1.ext4 file from the Starter Package form STM32MP1 series. The rest e.g st-image-weston-openstlinux-weston-stm32mp1.ext4, st-image-vendorfs-openstlinux-weston-stm32mp1.ext4 and st-image-userfs-openstlinux-weston-stm32mp1.ext4 are not changed.
The kernel is booting, no problem there. But the login promt does not appear. It seems that I got no errors at all, when I look at the full log. My thoughts is that what if bootfs not booting up the software such as command prompt?
The last snippet of the kernel boot log from UART4.

So what should it stand here? I have tried mmcblk0p8 (the rootfs partition) without success.

Update:
It seems that the U-boot can read the eMMC very properly without any issues.
