When Unbricking, the SuzyQ Board is no different then using a SuzyQable. Follow MrChromebox's Unbricking page (opens in a new tab).

Please note that mrchromebox UEFI only supports x86_64 Chromebooks, but the SuzyQ Board will support any ARM Chromebook that supports Closed Case Debugging (CCD) (opens in a new tab) (this should include all aarch64 Chromebooks).

Note that this WILL work on Ultramarine and Fedora. Grab the flashrom package from Fedora repositories, and cbfstool from Terra (opens in a new tab).

For other distros/package manaagers, check out flashrom packaging on Repology (opens in a new tab), and cbfstool packaging on Repology (opens in a new tab) (note that the package must include cbfstool).
