Hi,

Just received my AMP100 and Power controller. Looking at the instructions for connecting the power controller to the AMP100, can I confirm that you still plug the external power into the AMP100 socket? It's not clear from the instructions where the external power now comes in.

TIA

  Yes, with the Amp100, you can plug it into the Amp100. You just need to remove the jumpers at the 3-wire terminal.

  Hi again :),
  
  Trying to update the firmware on the Power controller.
  
  Using RPi 3B+, with the PC connected direct to the Pi via the ribbon and powering the Pi direct (with the jumper on the PC).

  Clean install of Pi3 HifiBerryOS.
  
  Ran /opt/hifiberry/bin/enable-updi - seemed to go ok and forced a reboot.
  
  subsequently issued pyupdi -c /dev/ttyAMA0 -d mega 808 -fr
  And got the following;
  
  Any suggestions why UPDI initialisation failed?

  Thanks

  DW - sorted

  Installed the 31 May 2021 version of OS, and that worked.
