[Pinebook Pro] 5.13 no longer boots from NVME

Great! That’s what I’ll try next.

Yeah–that’s what I thought too when I first installed my NVMe SSD in my PBP, but it turns out that only the Uboot code, which precedes the boot partition on the eMMC disk, must remain intact, but /boot and root partitions can be moved to the NVMe disk. It took me awhile to sort all this out. Someday, I might even attempt to flash my SIP and remove the necessity of retaining the Uboot code on my eMMC, but manjaro supports the functionality of the patches discussed here under Using as OS root drive

Here’s a conversation I had with Strit while I was learning:

Here are a few more links on the subject. The only compelling reason to risk flashing SIP is to be able to fully remove the eMMC, which saves power but I could not make a reasonable estimate of the savings from the eMMC datasheet. After this update failing on my system, I think I’ll continue to use eMMC to at least maintain a /root and boot backup!

I think this is pcm720’s latest code. I did successfully build it myself, but my native build was a bit smaller than pcm720’s cross compiled build (as such, I don’t know if I should trust my build to function in SIP) and, given that Manjaro provides and installs a UBoot that works well with NVMe (does everything Uboot can currently do, short of risking flashing it to SIP), I have never installed any of these builds. You’ll find PCM720’s earlier and probably outdated code on github too, if you follow various links:

According to my testing, the Uboot code installed by Manjaro contains the functionality of Nadia’s patch (including warm reset):
