I tried the seqence of instructions shown above and I now cannot power on my Pinebook Pro at all.
I just get a red light over the power indicator when I try to switch on the machine wheter I try to boot from the eMMC or the SD card.
I'd appreciate any thoughts \ help with this,
Thanks.
Oh dear I suspect what has happened is that is has partially worked and written to the emmc card and that would now prevent the sd from booting (happened to me and it is solvable dont worry!)
What you may have to do is confirm whether the light is red or orange first
Red sounds battery power issues
This may need a charge
Orange is an error
If Orange what I had to do was open the back of the pinebook pro up and using the instructions from the wiki here:
https://wiki.pine64.org/index.php/Pinebo...ble_switch
try to turn the emmc OFF and see if you can boot from the sd card
If you can do that then you should be able to retry the process in the tutorial.
This will need you to shut the pinebook down again and rebooting it. As soon as it turns on ie green light reflip the emmc switch back ON so the pinebook boots (*from the SD) and has another drive mounted (the emmc)
Then you should be able to try to repeat the process in the tutorial
I am assuming your sd card has the Ubuntu mate image still on it...if not you may need another pc to work from.
This may not be your problem but sounds exactly the same as what I had to do. ....in essence you are fooling your pinebook it has no hard drive so it boots to SD *(you had just written the mate image which stops the sd card booting first) Here you are bypassing the emmc card..booting sd and then emmc card ie in the wrong order
When sorted reassemble and remember what you have done...I have now had to do this several times (I tinker alot)
Also you will need to go to page 4 of the tutorial and install the correct uboot instructions that when sorted allow your pinebook to boot from SD card again automatically
Hope that helps
