problem revert "power target circuit from ICD4" off
Hello, I have a pic24f and LAN ethernet (with leds) controller into the same PCB plugged in with power. I disassemble because I needed access to program firmware easy access to pins.
> The configuration is set for the target board to suply its own power no voltage has been detected on VDD. Please ensure you have your target powered up and try again
I went to the project of Mplab > right button > Properties > ICD4 > Option Categories = "Power" > and set Power target circuit from ICD4 and now I can update the firmware,
The problem is that now the PCB don't boot unless
- that you have ICD4 programmer wire are connected
- if the option project is "power from ICD" is on in mplab
- the target microchip boot when I start debug mode (Into MplabX button)
even my supply energy is on from normal via. I updated the firmware with option "Power from ICD" OFF with the power from circuit but it doesn't work (led of ethernet don't work also)
It looks like the microcontroller, We are using the same PCB from 10 years ago with writing firmware with "set power target circuit from ICD3 or ICD4" without problems until now...
