Cannot flash the new firmware: "Missing USB drive"
Hi, I've tried updating my L14 BIOS with latest Pureboot after this doc : https://source.puri.sm/firmware/utility/#usage
The pureboot-librem_14-Release-27.1.rom file is generated with no error. But when rebooting and trying the update BIOS menu entry, it fails with "Missing USB drive". I've tried all USB ports with 2 different USB keys with FAT filesystem. These keys are readable with no issue. Any clue?
My current Pureboot version is 23.
