Bug Description

TGL-UP3
CID: 202104-28962
BIOS: TGLIFU1.R00.4304.A01.2107290604

To install a new image, I need to boot Ubuntu from a USB drive, wipe out the device's internal storage, and copy the new image over to it.

I have used the same USB drive to do this countless times - including on this TGL-UP3 to install Ubuntu Core.

However, now that it's been reflashed, I can't. If I go into the Boot manager in the BIOS and select the USB drive, it just goes to the GRUB shell instead of actually booting.

I tried resetting the BIOS to default settings within the BIOS but it still just boots to the GRUB shell when I try the USB drive.

So this problem only happens after the BIOS has been flashed?

The EHL system also has this problem but only after I changed the TPM setting.

In the case of this TGL-UP3 board, it had the problem immediately.

Next, let me try pulling the battery and see if that has a different affect than simply resetting the BIOS in the BIOS setting screen.

Disregard comment #3, it was meant for a different bug.

Older BIOS versions had an issue where turning off TPM would corrupt the BIOS causing USB to malfunction, before the board became completely inoperable until its BIOS was reflashed.

After reflashing this board, the USB ports operated normally.
