Summary
The serial bootloader for PIC32 MCUs is used to program
the user application to the Program Flash Memory (PFM)
using the UART serial port. The software comes with a PC
application that reads the user provided HEX file and writes
the program flash contents to the PIC32. This PC application
works in conjunction with the bootloader (BL) firmware
installed on the PIC32 MCU.
Summary
The bootloader for dsPIC30F/33F and PIC24H/24F devices
is used to load a user application on the target device
without using external programmer. The bootloader consists
of two applications:
1. Target side bootloader application which must be
2. Host PC bootloader application which communicates with
