core4418:can't flash from SD to eMMC /invalid partition info

Moderators: chensy, FATechsupport


on module core4418, I accidentally erased the internal eMMC.

Using the latest eflasher image [s5p4418-eflasher-android-lollipop-20181217.img]
on a sd-card, I can't flash the eMMC.

The SD card boots up, but the UI displays an error message: "Invalid partition info ret = -1"

The SD card is ok in general. I flashed my device using this card many times.

How can the internal eMMC be fixed to be flashed again?

Thanks in advance.
While you are testing and developing I would recommend the development image. Also just to make sure, i are you just looking to use balenaOS with out the cloud service? or do you intend to use balenaCloud as well?
