Description
Describe the bug
Cannot boot into alternate boot partition. HDMI does not work when GPIO 6 is pull low on power up to load this boot partition. CM4 is connected to a custom carrier board. It boots normally from MSD first GPT boot partition.
EEPROM boot.conf is configured to boot from Partition 3 (/dev/sda3) if GPIO 6 is activated (button press to trigger recovery on the custom carrier board).
# Boot from partition /dev/sda3 if GPIO 6 is pulled low
[gpio6=0]
PARTITION=3
/dev/sda1 is the regular boot partition and if GPIO 6 is pulled low, we expect it to boot from /dev/sda3. Both are FAT32 GPT partitions

Please note that if we use sudo reboot 3 it does not work either, it always boots from the first MSD boot partition regardless.
Steps to reproduce the behaviour
- Press button to pull GPIO 6 low
- CM4 not booting
