Just a few doubts. In regard to the NVMe adapter and related topic
Can the SSD NVMe drive be fixed to the board in some way? I can see the adapter slot in the board but cannot figure out how to fix the drive to the board. Are screws provided to tighten the drive to the board? Just so that it is not left loose.
Is it an only-NVMe adapter? Can it take plain M.2 SSD drives (non-NVMe) as well?
Any update on uboot and booting directly from SSD drive?
Thank you in advance!
M.2 drives mount to the carrier board with a brass spacer that fits into the notch at the end of the drive and screws into the carrier board from the back side. It's standard m.2 mounting, and very secure.
The NVMe adapter does not support SATA m.2 drives, it's just a passive breakout for 4x PCIe in m.2 form factor. You could, in theory, probably attach any other low-power m.2 PCIe device you felt like connecting to it; I've considered adding an Intel 2x2 AC wifi adapter to mine instead of an NVMe drive.
We're all waiting for mainline u-boot to mature for rk3399 before booting directly to NVMe/USB is going to be possible; mainline u-boot is still *very* much in the in-development alpha stage. U-boot and the kernel are going to take some time before they're feature complete and production ready and as of now you can't use one without the other, so it's not like we're just waiting on u-boot alone.
