Enable UART 1 on BB AI-64

This actually didn’t get updated, please rerun this section:

sudo apt update
sudo apt install --only-upgrade bb-j721e-evm-firmware generic-sys-mods
sudo apt upgrade

sudo /opt/u-boot/bb-u-boot-beagleboneai64/install-emmc.sh
sudo /opt/u-boot/bb-u-boot-beagleboneai64/install-microsd.sh
sudo reboot

PS, i’m updating sudo beagle-version to show this issue, so in the future this will help debug this:

debian@BeagleBone:~$ sudo beagle-version | grep bootloader
bootloader:[tiboot3.bin]:[/dev/mmcblk0boot0]:[U-Boot SPL 2021.01-gdaedcf37 (Sep 21 2022 - 23:44:04 +0000)]

and pushed out…

debian@BeagleBone:~$ sudo beagle-version | grep bootloader
bootloader:[/dev/mmcblk0boot0]:[tiboot3.bin]:[U-Boot SPL 2021.01-gdaedcf37 (Sep 21 2022 - 23:44:04 +0000)]
bootloader:[/dev/mmcblk0]:[/boot/firmware/tiboot3.bin]:[U-Boot SPL 2021.01-gdaedcf37 (Sep 21 2022 - 23:44:04 +0000)]
bootloader:[/dev/mmcblk0]:[/boot/firmware/tispl.bin]:[U-Boot SPL 2021.01-gdaedcf37 (Sep 21 2022 - 23:44:04 +0000)]
bootloader:[/dev/mmcblk0]:[/boot/firmware/u-boot.img]:[U-Boot 2021.01-gdaedcf37 (Sep 21 2022 - 23:44:04 +0000)]

All 4 files need to be the same version on bootup…
