EDK2 image and embedded ubuntu(eMMC) booting

kty

hi.
I'm trying to make UEFI Image based on EDK2(Tianocore).
Building and downloading UEFI image is done successfully.
But I got some problem when booting from embedded Ubuntu on eMMC.
When I try to boot from eMMC, Ubuntu does not started but UEFI shell does appeared.
After running grub.efi on fs0:\efi manually, Ubuntu starts.
What is wrong?

Hi @kty

Are you using the code and documentation available from the Intel website?

If so, I would suggest to post your questions on the Intel Forums: https://forums.intel.com/s/topic/0TO0P00000018NFWAY/embedded-intel-atom
