Hardware:
Raspberry Pi 5
Pi 5 power supply
USB stick with Homebridge OS flashed via Raspberry Pi Imager
Problem:
My Pi 5 won't boot reliably. I have to plug/unplug the power cable about 10 times before the green LED finally lights up and the system boots. Most of the time I only get the red LED (power), but no green LED activity.
What I've checked:
Power supply: Using official Pi 5 PSU
Connections: All cables properly connected
Boot files: All firmware files (bootcode.bin, start*.elf, fixup*.dat) are present on boot partition
Current config.txt:
# For more options and information see
# http://rptl.io/configtxt
# Some settings may impact device functionality. See link above for details
# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on
# Enable audio (loads snd_bcm2835)

# Enable host mode on the 2711 built-in XHCI USB controller.
# This line should be removed if the legacy DWC2 controller is required

Current cmdline.txt:
console=serial0,115200 console=tty1 root=PARTUUID=8e357ccf-02 rootfstype=ext4 fsck.repair=yes rootwait
Questions:
Is this a known Pi 5 bootloader issue?
Could it be related to the Homebridge OS image compatibility with Pi 5?
Should I update the firmware files on the boot partition?
Any specific Pi 5 config.txt settings that might help with boot stability?
