Mark,
2.? I have found that if you use one USB cable from pc to the USB connector on the ATU-10 to provide power, then there is no need to do your other points (Advanced etc)
ie You need two USB connections to the PC
- 1 to the USB socket on ATU which will provide power.
- 2 to your Pickit.
(If you don't have a battery installed make sure the output of the TP4056 is about 4.1V or so.? Occasionally I have seen this chip not provide any output voltage.?? If i try again, it's OK.)
