Okay, after buying a 1.8V SPI Flash programmer, banging my head for some time, I think the situation is this:
- The Version 9.0.0 BIOS on Radxa’s Download Page ( https://docs.radxa.com/en/orion/o6/download#bios ) DOES NOT work with 64GB Boards.
- The other Version 0.3.0-1 listed at the top also DOES NOT work with 64GB Boards.
- The only version that I managed to get working was the link tucked away below under compatibility list: https://github.com/radxa-pkg/edk2-cix/releases/download/0.3.1-1/edk2-cix_0.3.1-1_all.deb
IF YOU HAVE A 64GB BOARD, I WOULD STRONGLY ADVISE AGAINST ATTEMPTING A BIOS UPDATE AT THIS POINT IN TIME. IT COULD LEAVE YOUR BOARD IN AN UNBOOTABLE STATE AND REQUIRE YOU TO PHYSICALLY FLASH THE BIOS CHIP IN ORDER TO RECOVER.
If you do end up in this state, the instructions to follow for flashing are here: Guide: Flash Bios with CH341A (macos/linux)
@RadxaYuntian It would be nice to have prominent warnings on the BIOS download page indicating that the Version 9.0.0 BIOS is not compatible with all 64GB board variants.
