I have Ubuntu installed on my SD card and manjaro on emmc. It boots fine into Ubuntu. However removing the emmc with SD still in, the device will turn on but remain on black screen. So I tried to flash the Ubuntu image on emmc and remove SD card. Again, turns on but remains on black screen. I then reinstalled manjaro on emmc and put SD card back in, it boots fine into Ubuntu. Next I will try to duplicate my SD card to emmc to see if it boots. Its possible that running ubuntu via sd and updating os may have fixed the boot. I will try tonight. I find it odd that it boots from SD card but will not from emmc
No editing should be needed, but some images are not so good
It is often hard to tell just exactly what is wrong, unless you have a serial connection
If there is a SD inserted, if there is a bootable image on it, the emmc uboot
will find it 1st and boot from it (if the search path has MMC1 as first item, this is common)
If it is a non-bootable SD or absent, then nvme0, then usb0 will be searched, then emmc will be examined
uboot is looking for extlinux.conf or boot.scr
>would it work if I made an image with partitions from SD card and duplicated to emmc?
I would guess not
--edit--
>The spi does require uboot to be flashed to it.
Any uboot will do (if it is "good") wherever it is (not usb)
Flashing uboot to SPI, at this time, is NOT recommended unless you are somewhat "expert"
All of this is a bit "beta", somewhat immature
And, if you read closely, this is more for rockpro rather than pinbookpro
