HI all,
I have a raspberry 3+ with iqaudio dac pro and a remotepi board.
I recently realized i had to make some hardware adjustements to have the system properly working due to a GPIO conflict between remote board and the DAC board.
Here you can see the official instructions.
I soldered the two open pads as required and than i decided to completely remove the pin n.12 (GPIO18) which connects the dac and the remote board,
instead of completely removing the copper trace wich starts from there.
I thought the result would have been the same (avoiding to break the board) but when i plug the power Rasp doesnt turns on.
Why is my solution wrong? Looking at the board a cannot see any difference between removing the pin and cutting the trace.
Thanks for any contribution or suggestion
I assume you did connect power to the RemotePi board (and not the Pi). In that case the Pi won’t start just by plugging in power. You would have to use the power button of the RemotePi board or a remote control that has be learned in to the RemotePi (as described here in the section “Configure the RemotePi Board to power on and off using your remote”).
If you have tried the above without success: Does the Pi start if you only connect the RemotePi board (and not the DAC)?
Yes, both of them.
first Plugged the remotePi board no power to the raspberry board using the button, only remote board lights up;
then plugged the rasb board and everything is ok.
At the moment I have no idea, except possibly a hardware defect. Did you check if there is +5V power on pins 2/4 of the RemotePi board’s connector to the Pi after pressing the power button?
No multimeter at this moment.
The green led on the remotepi board.
The rasp seems to be completely unplugged, as if no power arrived.
At this moment iìm using the original rasp power unit (2.5A)
PS:
how do you quote parts of my msg? I can only do a simple reply
I think the next thing to check would measuring if there’s power on pin 2/4 of the RemotePi board’s connector after pressing the power button as mentioned above. Maybe you can borrow a multimeter from someone. Be careful not to cause a short!
