I am designing my own PCB around a PIC32MM0064GPL028 microcontroller. Breaking down the steps below-
- I have built a simple breadboard version first, inspired by PIC32MM curiosity development board.
- Here is the schematic of the prototype programmed using PicKit3.
- The prototype connects and programs with no issues. And the same code works perfectly on the curiosity development board. This indicates that the issue is in the schematics or components.
- Links to the components I am using - PIC32, crystal, 18pF capacitor for crystal, 10uF capacitor for Vcap, Reverse Protection mosfet.
I am not an electronics engineer and have been playing with arduino and similar boards for quite a while now. However, this is all very new to me and probably the issue is a silly one.
It'll be super helpful if you could help me debug the issue. I can upload the code if it helps? Thanks.

It looks like you made a mistake in your schematic:
PIN 8 of the PIC (VSS) is connected to PWR and PIN 13 of the PIC (VDD) is connected to GND. VDD must be tied to the power, and VSS to the GND.
What is the voltage of PWR? Why don't you use 3V3 for MCLR and VDD/AVDD?

turns out it was just an incorrect connection to MCLR pin. I connected the 10k resistor in the wrong position in the breadboard. The schematics are fine and the prototype is working now. Thanks a lot for helping and let me know if you want me to share something else.

There is nothing connected to pin 3 (LED1) of the PIC on your breadboard, neither to pin 7 (LED2). Double check your connections.

turns out it was just an incorrect connection to MCLR pin. I connected the 10k resistor in the wrong position in the breadboard. The schematics are fine and the prototype is working now. Thanks a lot for helping and let me know if you want me to share something else.

Congrats for finding it. This error was hardly detectable from the initial picture in your post. For next questions, I'd recommend providing clear pictures (from different angles, showing the whole setup etc) and correct schematics. Good luck with this board!

Thanks. You are right, I was assuming the issue is in the schematic itself, or the components I am using. No assumptions next time! Thanks.

Shouldn't the LED on the development board have a resistor in series as well? And why is it connected to MCLR? You may have damaged RB13 as it should not exceed the abs max ratings (chapt 26.0 datasheet)

The LED on the development board is working fine even without the resistor (although a resistor is recommended, you are right). The problem is in the breadboard circuit (resistor included) which is not triggering the led.

What voltage do you measure on pins 3, 7 and 24? If you measure 3.3V, check the polarity of the LEDs.

@Dhruv The series resistor is not just recommended, it is required. Otherwise you WILL damage your LEDs and/or your PIC

@Huisman it shows 0.16V. It goes high for almost half a second while the code is uploading, and the goes back to zero. Leds are placed correctly.
