Unbrick rock2.
Is it bricked?
When writing update.img to nand RKBatchTool failes with following message: "Prepare IDB Fail" (or similar error messages like "IDB download failed" when writing to emmc with other tools) The board is "bricked". It is not really bricked, first make sure there's no SD card connected while trying to flash the device, otherwise the bootloader is corrupted at this time, you can always recover it.
Release version SoM
The emmc shortcut pin was put on the top of the som, makes it easier to unbrick it
To recover it:
- Turn off Power, plug OTG USB cable in the PC
- Connect the emmc shorcut pins with a needle and plug in the power cable.
- After Plugin remove needle connection. In RKBatchTool the square icon should now show up blue (if it isn't blue, retry).
- Click the restore button and upload an update.img
Beta version SoM
Notes
For upgrade_tool under Linux, you should read Maskrom if successfully shortcut the pins.
