I was normally using my chipkit max32 and after uploading a code (I don't think the code is the problem, since i uploaded it to my other max32 and it's just working fine) my max32 just stopped working. I have two and comparing the two max32 when connecting it to the computer the Led on the back (LD4) won't blink and the serial leds (LD1, LD2) blink like every 3 seconds. The power led is just fine. What can it be? Is there any way to factory reset it or download the firmware again?

Does the board get detected by the USB stack of the PC?

There's two distinct components to the MAX32 - the main microcontroller (PIC32MX795F512L) and an FT-232 chip which interfaces it to the USB port.

If the FT-232 chip has gone faulty it could be causing the PIC32 to remain in a reset state. If the FT-232 chip is fine, it could be the PIC32 that is at fault, and reloading the bootloader may fix it. You'll need a PICKIT3 or similar to re-flash the bootloader.

When I connect it to my PC and press upload it just stays and never ends uploading.

Does it appear in Device Manager (Windows) or lsusb (Linux)?

Which version of the IDE are you running?

I just found out that the max32 is always on reset mode like I was always pressing the reset button.
