@Bullet64 I'm glad you're having some success with this. You might be aware of this already, but in this log:
it shows U-Boot is reading /boot/extlinux/extlinux.conf off the SD card, not the NVMe device. However this would still work if you tell Linux the root filesystem is on NVMe, e.g. with a root=UUID="..." entry in the kernel command line, since Linux would later detect the NVMe device and mount the root filesystem on it.
On the other hand, it *should* be possible to have U-Boot read /boot/extlinux/extlinux.conf and the kernel and initrd off the NVMe device directly, and not involve an SD card at all.
I've tested that booting Linux from a SanDisk USB-stick works (if it's plugged in to either the USB 3.0 or USB 2.0 Type-A ports) but that USB-stick would only be using USB 2.0, I don't have any USB3 disks to test with at the moment. I'll see if I can get one to try out.
Out of curiosity, is boot from a USB3 disk working for you with the Rockchip downstream/vendor U-Boot (https://github.com/rockchip-linux/u-boot/ or one of the other U-Boot builds which is derived from Rockchip's source code, e.g. Ayufan's)?
