Just a few ongoing notes on building a reset switch for some of the Oranges. Currently unplugging the unit, or turn the surge protector on and off, is the only way to restart the board after safe shutdown. A surge protector with individual switches is a cheap and easy solution if you have multiple boards, but I was still curious about the possibility. I originally thought it was not possible, but now I’m unsure.
Going to the PC2 schematic, there is a RESET-Option indicated under CPU. Q9 is located between the IR and AV ports. There was a discussion about this.
- Connecting a button parallel to C301 should provide a hardware reset option.
- GND applied to Q9 collector is also fine.
- So, the switch needs to short C301 to VCC-IO, or C65 to GND. C65 is on Q9 collector pin 3, you need to short it to GND (pin 6).
Also look at AR100 and related Armbian forum discussions.
