I think you need to get Tow-Boot on the SPI.
I am not sure pine64 uses the wiki anymore, I think they moved everything to "documentation"
From the RK3399_boot_sequence
- loading from NOR flash on SPI1
- loading from NAND flash on SPI1
- loading from eMMC
- loading from SD on the SDMMC controller
- bringing up the OTG0 USB controller in device mode and accepting control transfers to load programs
The eMMC may have an issue booting. You may need to Disable the eMMC so you can boot off the SD. Once booted off the SD, I personnally would try to get Tow-Boot on the SPI.
Thank you @mikehenson !! That's good to know about the documentation!
I don't have any time today, but I'll try to do as you said tomorrow!
@mikehenson I burnt Tow-Boot to SPI, which worked great, but then after removing the sd card screen still remained black, so removed the back cover, and maybe the emmc switch had been labeled "the other way round", it looked like off, so anyway I switched it and then, everything would have worked just as you said ...
But, unfortunately I hadn't read the instructions about what not to do when removing the back cover, and I broke the plastic stuff fixing the screen... and so, ruined it :-((((((
Anyway, many thanks again, it would have worked great really.
