Jumpdrive broken? eMMc broken

[Uturn]

hullo, I try to flash a fresh OS to my PinePhone's eMMC via jumpdrive, I flash from e Mac with Etcher, the Pinephone looks ok, but zero success wiht Manjaro Plasma Mobile (stays black), little success with Manjaro Gnome Mobile (stuck at manjaro splash screen). Is it possible the eMMC is damaged, or did I screw up somenthing with Jumpdrive? Manjaro Plasmal Mobile from card starts up normal.

before going on some deeper things. i recommend command "sync" after flashing, whatever is the flash command. more experienced users usually use command "dd". "sync" guarantees that writing buffers are written to the disk. some cases "dd" or other program does it afterwards by itself, but not in all cases.

i also noticed a weird bug in a host system, that it sees sizes of pinephone memories wrong, of course flashing fails. reboot helps, but reinserting cards or cable do not. "lsblk" helps.

thank you. Problem is I can't boot from eMMc, I can only boot from SDcard and sync on that system. Whatever I install on eMMc it does not seem to boot.

seems that you use windows, if yes, then "safe remove" is recommended. "sync" in this case is intended only for linux as a host for mass memories like usb memory.

if you can boot sdcard, you could test internal memory from booted sdcard. but giving accurate commands is problematic.

however, some distribution require tow-boot, but if you can boot sdcard, this is not an issue.

no, I am a mac user. I re flashed then card with jumpdrive on it and now it seems to work. Strange because a while ago it worked too. Maybe this jumpdrive is not very stable?
