CRC error on boot from nvme w/ubuntu?

Managed to get nvme boot working; thank you to everyone for the assistance. I had a question about CRC issues with SPIFlash. Is this caused by UEFI hitting nvme, failing, then falling back on the onboard SPI?

No, this is just u-boot looking for custom environment variables in SPI flash. Since your SPI flash is probably empty, it fails with a CRC error.

You can ignore this message.
