V1 carrier board won't boot from imaged USB stick

I've been procrastinating a long time. I've had the V1 carrier board and CM4 (8GB memory 32GB eMMC) for a long time. Received the CM4 in late 2022 after a long back order at Digikey. Now I'm trying to use it.

First I thought I might use RPIBOOT via a Windows 11 laptop to see what happens. Used a USB-A-to-USB-C cable to connect laptop to carrier board USB port. Ran RPIBOOT, then powered up the carrier board. I saw the LEDs on the four network ports briefly light, but nothing seemed to happen.

Next I connected a monitor and keyboard to the carrier board, and powered it up again. I could see the CM4 was trying to boot.

Next I imaged "desktop-interceptor-raspberrypi-cm4-2024-04-24.img" to a USB stick using the Raspberry Pi Imager. I've plugged the USB stick into one of the USB ports on the carrier board. I've connected a monitor. The CM4 won't boot off the stick. Here's what I see:

Now I seem stuck. I must lack some bit of knowledge I need to make this thing go. Any advice would be appreciated.

Hello @abreuma677!

We're happy to hear you are finally getting to use your board.

Our board does not support this: "First I thought I might use RPIBOOT via a Windows 11 laptop to see what happens. Used a USB-A-to-USB-C cable to connect laptop to carrier board USB port."

On what system (OS) did you write our image to your USB flash drive? The USB on the board is working fine. It just didn't "see" your flash drive.

The hardware FAQ could use an update, because it indicates RPIBOOT can be used:

Q. Is there a minimum CM4 bootloader version required by the Axzez Interceptor Carrier Board?

A. The only requirement is that you have the ability to boot via USB. This capability was released with the RPi4 bootloader eeprom version 2020-12-14. To install this (or newer) bootloader, please follow the instructions here to setup and build "rpiboot". Then follow the instructions here to flash the latest or desired eeprom version. We recommend the "BOOT_ORDER=0xf215" for setting up our provided operating system.

This should mention that a real CM4/CM5 carrier board is needed for these things.

I was able to image a USB stick on a Raspberry Pi 3, and it worked. I loaded OMV. Doing updates after that install didn't seem to go very well, but it's running. Maybe I'll try another OS.

Sorry about that, @abreuma677. I was specifically referring to this "Used a USB-A-to-USB-C cable to connect laptop to carrier board USB port." The "instructions here" part of the FAQ tells you that you need to use a Raspberry Pi IO Board (aka CMIO) to use RPIBOOT. I thought you were saying that you were trying to do this with our Interceptor Carrier Board, which will not work.
