Issue description: Inch Duo is in booting stage and the reboot of the station doesn't help.

Sometimes this happens due to voltage fluctuations on the motherboard. The SOM then becomes corrupted and stays in boot loop.

To prevent the voltage fluctuations we recommend to replace the motherboard with never version that has different capacitor(H-1029-A) or add a specially crafted cable with the capacitor (IDENT).

Here you can access a guide for replacing the motherboard in INCH DUO: INCH DUO - Motherboard replacement

Replacement process:

Hold the SOM with fingers and carefully lift it (SOM is connected to the motherboard with two multi pin connectors and two PCB spacers – marked in red)

Install PCB spacers on motherboard and align new SOM with PCB spacers and multi pin connectors on motherboard.

Firmly press on SOM to secure the connection with motherboard (audible click).
