USB Bootloader

The PIC32-avrdude-bootloader communicates over either a serial port (UART) or the USB port (on those pic32 chips that support USB.)  It can be built for either serial or USB communication with the PC. The bootloader communicates with the avrdude executable on the PC side of the connection. The following boards have been tested using the PIC32-avrdude-bootloader:

• Microchip PIC32 USB starter kit
• Microchip PIC32 Ethernet starter kit
• UBW32 - MX460
• UBW32 - MX795
• Fubarino SD
• Fubarino Mini

In order to use this bootloader, you can either download the full source from github, or just pick and choose the HEX file that is right for your board. There are three bootloaders that have been created for chipKIT and chipKIT compatible boards:

• PIC32-avrdude-bootloader - This new bootloader for MPIDE/chipKIT PIC32 boards is buildable for all currently available  chipKIT boards (UNO32, MAX32, uC32) as well as other PIC32 based boards like the UBW32 and Fubarino boards.
• pic32-Arduino-USB-Bootloader-original - This is the original version of the bootloader that works only if compiled with the C32 v1.xx version due to changes in the way that newer version of C32/XC32 handles the linker scripts files.
• pic32-Arduino-Bootloader -- This is the older original version of the bootloader which supports only Digilent uno and mega pic32 boards.This bootloader is compatible with v5.8 of avrdude.
• For Digilent pic32 boards, it is highly recommended to download the Digilent official bootloader from the Digilent website at http://www.digilentinc.com/.
