If "J4 CNTR" is connected, the station will not turn on first. I tried disconnected J4 CNTR, turned on the station, then connected the J4 CNTR cable, and the station started. I tried only "Vin" pin in J4 CNTRL connected, and the same problem arises that I wrote above. What could be the problem?
For that you could check ZD4 and its circuit up to pin14 of the controller

Bus Pirate Support / Powering a sub-circuit from BP3 while host still powered
Last post by mr0mega -
 Hi

I am struggling to sniff SPI traffic, BP3 keeps telling me it couldn't keep up. As I want to read some registers, would I be able to power the device using the BP3 while still powered by the host device, and then unplug the host device to keep the power going to the device I'm trying to interact with or will that damage the host/sub-circuit/BP3?

The sub-circuit is a

https://www.hoperf.com/%20modules/rf_transceiver/RFM69HW.html

Voltage to sub-circuit is 3.2v from host device.

Hi, I checked what was described. Everything seems fine, but reflashing doesn't work. :(  ("Unable to connect to the target device.
Failed to get Device ID").

I have another bigger problem:
If "J4 CNTR" is connected, the station will not turn on first. I tried disconnected J4 CNTR, turned on the station, then connected the J4 CNTR cable, and the station started. I tried only "Vin" pin in J4 CNTRL connected, and the same problem arises that I wrote above. What could be the problem?
Do you have 3.3V and -0.6V at front board J9 (PWR) connector?

Hi Blzs21, check the power connections 3.3V from schematics for pic32, R11 if it is  not cracked and related pins of pic32 for a good soldering, do the same with prog. pins of pic32 to prog. connector.
check 8Mhz crystal and its caps C55, 56 - you will need them after successfully programmed pic32 and follow the already explained method fot the programming of mcu here or from internet.
Do not connect the two power sources 3.3V ( use one only-from programmer or from the board) the time of programming.
