Windows IoT Community

Hey rpi_guru, sorry to hear you're having trouble. I've been running a Pi 5 with the same OS for about a week now without any major boot issues. Did you follow the official imaging guide from Microsoft? Sometimes, using a specific bootloader or partition setup can be critical for ARM devices.

Also, check your power supply. While the Pi 5 has updated power requirements, a slightly underpowered or unstable supply can cause all sorts of weird behavior, especially during the boot sequence.

Hi User_Alex, thanks for the reply!

Yes, I followed the official Microsoft guide precisely, using the recommended tool and image. I'm using the official Raspberry Pi 27W USB-C Power Supply, so I don't think the power is the issue. I've even tried a different identical power supply.

One thing I noticed is that when it fails to boot, the activity LED on the Pi doesn't seem to do anything specific. It's just off or solid, not flashing.

Hello rpi_guru, DevSupport here. We're aware of some early boot inconsistencies on certain hardware configurations with Windows IoT on ARM. Could you try flashing the latest firmware to the Pi 5's onboard EEPROM?

You can do this by booting into Raspberry Pi OS, opening a terminal, and running:

sudo rpi-eeprom-update -d -f /lib/firmware/raspberrypi/bootloader/stable/pieeprom-2023-10-17.bin

Ensure you use the latest stable EEPROM version available. After updating, power off, then try booting Windows IoT again.

Thanks DevSupport, I'll give the EEPROM update a shot right now. I hadn't considered that. Will report back with the results!
