Re: Can't enable uart for Ubuntu SOS

hi Shuai,

If you follows https://projectacrn.github.io/latest/tutorials/using_grub.html?#installing-self-built-grub

then you should not replace grubx64.efi to /boot/efi/EFI/ubuntu since grub-mkimge -p parameter is incorrect. Ubuntu GRUB is built with its own build script and parameters.

please put efi application to your "-p" specified folder, (maybe you can try "grub-mkimage -p /EFI/grub ..." to replace your Ubuntu grub efi but I am not sure it can work, depends on your ubuntu version.)


BR,

Victor

Hi Victor,
        update the grub2.05 according to this https://projectacrn.github.io/latest/tutorials/using_grub.html?#installing-self-built-grub, copy the grubx64.efi to /boot/efi/EFI/ubuntu . But grub cannot boot ubuntu to startup. Is the file in the wrong place?
