JI'm just including the log this time so that you can see that I did use the proper images....

Once again, thanks.

@belfastraven thanks for testing, and pasting the full log here. Looks like your NVMe device is detected OK, I suspect the "Unrecognized filesystem type" problem is just because there is no BTRFS support in this build (it's not enabled in U-Boot by default).

I enabled BTRFS in the config and re-built U-Boot, I haven't tested this yet but you could try using the resulting build, attached: 
Edit: if you need the SPI binaries from this build, they can be downloaded from this build artifacts page.

I now have armbian booting from SPI flash u-boot,  its great to be booting from SPI running 5.4.8 kernel with current u-boot.  I have booted sdcard, emmc and pcie NVME.  I haven't tried with USB ports yet.  I had gone back to ext4. 

Have you thought of including an image like your flash image, that would just 0-out the flash in case of problems.  I believe ayufan has one https://github.com/ayufan-rock64/linux-u-boot/releases/download/2017.09-rockchip-ayufan-1065-g95f6152134/u-boot-erase-spi-rockpro64.img.xz  

thanks again.
