Re: Can't enable uart for Ubuntu SOS

Liu, Fuzhong

Hi zhangshuai

Could you please try "make install" instead of copy the grubx64.efi?

It works for my setup:
root@acrn-OptiPlex-9010:/home/acrn/work/grub-2.04# make install
root@acrn-OptiPlex-9010:/home/acrn/work/grub-2.04# grub-install -V
grub-install (GRUB) 2.02-2ubuntu8.17
root@acrn-OptiPlex-9010:/home/acrn/work/grub-2.04# reboot
root@acrn-OptiPlex-9010:/home/acrn# grub-install -V
grub-install (GRUB) 2.04

Hi Victor,
        update the grub2.05 according to this,
copy the grubx64.efi to /boot/efi/EFI/ubuntu . But grub cannot boot ubuntu to startup. Is the file in the wrong place?

Thanks and Best Regards,
