I used an image downloaded from the Yandex link in the first message, with GNOME and Jammy, the latest version there (23.02).

It turns out it wasn't my power supply. I had partitioned my NVMe into two, one for /boot and one for root, and told it to install to the root partition on /dev/nvme0n1p2 . Had the same issue: hang at boot time with the blue light on continuously (but not looping through a power cycle: the blue LED never turned off, as it would in a boot loop). Then I had a flash of "maybe..." and repartitioned the NVMe as one partition, then installed to it with armbian-config. Success! I get a lot of messages at boot time scrolling through the console that I can't read (I use a 4K monitor, and it's tiny text), but it does run without the SD card in place. Yay! Now to see how fast it runs the application I got it for.

Well, that went not much of anywhere...I did the install to MTD+NVMe, and at boot, the machine came on, the blue light came on, and then never started blinking. I've been using a power supply that came with my Pi 400, but I suspect that does PD. Now to find one that doesn't and is beefy enough to run this machine. But...the machine does boot from SD after doing the installation to MTD+NVMe with that same power supply. Is it really the power supply, or something else?

I could install to NVMe, but it didn't offer to load things into the SPI. I actually did the NVMe install by selecting MTD/NVMe, but aborted the copy to MTD.

I wasn't offered SPI + NVMe/SATA; I only got boot from SD or MTD. This is on the 20230209 image, booted from SD with an NVMe installed. (It found the NVMe just fine.)
