Well, after a long search and thanks to this thread
http://forum.pinguino.cc/showthread.php?...oader+mode
the PIC32MX250F128B is working like a charm!
Just for completness, these are the steps that I made to make it work:
- Go to LibUSB-Win32 folder and execute Filter Wizard. You will be presented with a list of devices connected to USB.
- Select you device based in the VID/PID numbers. In my case VID 0x4D8 and PID 0x003 REV 0x103. You can find this numbers in device properties -> Hardware ID.
- Select you device and choose "install a device filter".
That's it.
I followed the steps to enter in bootloader mode as stated in wiki page and then download the program to the board without problems.
