Tow-boot problems and restoring uboot
#11
(05-18-2022, 11:53 AM)wibble Wrote: Based on the doc linked in post #4 I think zeroing 32k starting at an 8k offset should remove enough of the u-boot from the SD for the pinephone to boot from eMMC, but I haven't tried it. Something like this, assuming I've remembered which device is uSD and which eMMC - do check!
dd if=/dev/zero of=/dev/mmcblk0 bs=1024 seek=8 count=32

 i have tried it and it booted from emmc like it should

 but when i tried to tell tow-boot to boot from sd card the boot hanged

 so i think that dd command wipes too much of u-boot

 and it is for use the sd card as storage only

 ezik

multi-distro sd doesn't boot either when i tell it to boot feom emmc

and then tell tow-boot to boot from sd again

after the aqua led the phone vibrate three times with red led then yellow

and fall back to boot from emmc (manjaro phosh if it matters)
