Reflashing an UP board

Reflashing an UP board

Requirements

• 2x USB flash drives.
  • One formatted exFAT, upon which we'll place an uncompressed Ubilinux ISO and flash-image.sh script as files.
  • One flashed (via balenaEtcher) with a Linux live distro, such as Linux Mint.
• Ubilinux IMG: https://lama-images.fra1.digitaloceanspaces.com/aaeon-upboard/ubilinux-4-truncated.img.gz
• Linux live ISO: https://mirrors.seas.harvard.edu/linuxmint/stable/21.2/linuxmint-21.2-xfce-64bit.iso
• flash-image.sh script: https://lama-images.fra1.digitaloceanspaces.com/aaeon-upboard/aveiro/flash-image.sh

Step-by-step

1. On one USB, flash a Linux live distro using balenaEtcher (https://etcher.balena.io/).
2. Uncompress the ubilinux-4-truncated.img.gz file so that you're left with a ubilinux-4-truncated.img file. On the second USB (formatted exFAT), copy the uncompressed Ubilinux image, as well as the flash-image.sh script.
3. Disconnect the camera USB cables, but note the port from which they came, as they'll need to be placed back into the same port.
4. Insert the Linux live USB drive and a USB keyboard into the UP board. Power the machine and enter the BIOS (should be with F7), setting it to boot from the live USB.
5. Once in the live USB's desktop, open a terminal with CTRL + ALT + T. Run sudo su
6. Plug in the data USB drive and navigate to it through the terminal: cd /media/linuxmint/USBNAME
7. Change the script's permissions so you're able to run it directly: chmod u+x flash-image.sh
8. Run the script as below, replacing the machine model (sintra / gaia / tejo) and printer model (nippon / zebra / none):

./flash-image.sh install /dev/mmcblk0 ubilinux-4-truncated.img upboard gaia nippon

9. Once complete, run sync and then shutdown now to power off the board. Unplugg the USB drives and keyboards, place the camera USB cables back into their original position (important) and boot into the newly flashed board.
