GPT ESP Partition: Unable to read partition as FAT #558

Closed ragazenta closed 6 months ago

ragazenta commented 6 months ago

Describe the bug

Hi, I'm unable to boot SD Card if I use GPT scheme with EFI System Partition (ESP) as bootfs.

I've read previous related issue #359 and it should've already been fixed in e87bc4da8d983aa6e7c3edcf8cd823b76e50e65e, but currently it's not.

Steps to reproduce the behaviour

I'm using custom OS image in SD Card and official RaspiOS Bookworm Lite in USB.

Booting from USB to see bootloader version.

Is it because FAT 16?

It's weird why the bootloader detect it as type: 16 when lsblk shows FAT32?

pi@raspberrypi:~$ lsblk -f /dev/mmcblk0

I guess this is not issue from here, but from the tool I use to create os image (mkosi, see here)

Also, it doesn't feel right to use esp (efi system partition) as raspi bootloader is not uefi.
