I wanted to share my experience briefly:
If you have an NVMe SSD already installed (empty, unformatted) and then try to boot an OS from the SD card, it will not work!
You have to remove the NVMe SSD before you can boot from the SD card!
Booting from SD card fails when NVMe is installed
That works for me. It could be a power issue.

I have the same setup. With my empty nvme I was able to boot from SD or emmc. Once booted I was able to see the nvme. You could have a power supply problem. This is the way the problem shows up. SPI was not loaded.

As @PatriksRetroTech mentionned it can be power issue, or it can be related to the distro. At least that was my experience.
hi, I want to install android in sd card and ubuntu on nvme. Did you have some idea about choose OS when booting?
As far as I know you can’t boot from anything else if you flash the SPI chip memory which allows you to boot from NVME. You can “choose” boot order by having or not having an SD card inserted while your other OS is on eMMC (SD is earlier in the boot order).
