support the PIC32MX120F032B (id 0x04 0xA0 0x60 0x53)
Hey
how hard would it be to recompile some pinguino32 bootloader to support PIC32MX120F032B (id 0x04 0xA0 0x60 0x53) ?
I have this PIC at hand and it would be great if I could get it PINGUINOED?
Any ideas?

Enough flash for what? For bootloader?
How hard would it be? I have this chip at hand and I'd really like to program it from Pinguino IDE

I don't understand the ICSP feature of PinguinoIDE. Is it using pickit2 to upload the bootloader? Well, the PICs require 12V voltage on MCLR, so I can't see really any other options...
Yea, I really want this PIC to work with PINGUINO IDE bootloader, even if the program memory is very small. I won't have any better in the future (also due to the fact that the better version don't have the 5V tolerant programming lines, but that's different story).
I have PIC32MX120F032B at hand and I am able to program it (it's blinking the LED happily right now), so any hints are welcome!

"Lots (all?) of PIC32s have 5V-tolerant pins."
I must diseagree.
PIC32MX220F032B - no 5V tolerant PGD/PGC lines

PIC32MX250F128B - no 5V tolerang PGD/PGC lines
http://ww1.microchip.com/downloads/en/De...01168H.pdf
PIC32MX270F256B - no 5V tolerang PGD/PGC lines
http://ww1.microchip.com/downloads/en/De...01168H.pdf
This is frustrating, but it makes me unable to program them (without doing some signal level translation), even while I am still able to program PIC32MX120F032B.
If you see ANY PIC32 suitable for pinguino with 5V-tolerant PGD/PGC lines, then please just name it and I will be very thankful!

My PICKIT2 is only able to supply 5V signals on PGD/PGC.
The 5V on 3.3V-only pins would most likely damage the chip. Resistor divider is in my opinion not a good idea because PGD line is bi-directional.
MX170 you say? Well, indeed. PIC32MX170F256B has 5V tolerant PGD/PGC pins... but wait... does it have USB?!
