Thank you!
Am experiencing some difficulty getting pmOS to eMMC.
Seems there could be a boot partition error & am reading more about it, now. https://wiki.postmarketos.org/wiki/Troubleshooting
I get the message, ''Card did not respond to voltage select! :110'' when trying to flash eMMC. When flashing from Lexar 32 G SD in Sandisk Mobilemate+ reader then it goes to pmOS. When I put the SD card into the Microsd slot on PBP, then it tries very hard to boot into pmOS with its logo appearing but the message- "boot partition not found" appears and there is the link to pmOS troubleshooting.
Am not experienced with dd command, and hopefully don't have to use it, but it is the command in the Getting started section? https://wiki.pine64.org/wiki/Getting_sta..._a_SD_Boot  https://wiki.pine64.org/wiki/Getting_sta...D_on_Linux
Am typing this from PBP. What a lovely laptop! I hope to get it set up, soon. Any further suggestions or advice are welcome. I realise I have much to learn but this is one reason I got PBP.
Cheers

does this look similar to the issue you're having with the emmc install? if so, there may be a fix in the thread, but it appears you'll need a UART cable for some of the steps.
