Hello everyone,

I am trying to integrate a bootloader on my PIC32 but I don't know how to do it.
The purpose is to connect the PIC to a computer from my USB port and to be able to upload new firmware to the PIC.

Microchip developped the EZBL to create a bootloader using a USB Thumb Drive or I2C/UART.
It doesn't seems to have any function for what I want...

I was wondering how should I develop the bootloader (do you have any tutorials, exemples, ... ?) and how do I integrate it to the PIC.
Do I need to erase my firmware from it, just integrate the BL and then upload the firmware from the BL ?

Thank you in advance for any help

 

Bootloaders are tricky, but the complexity of the memory organization of the PIC32 makes it even more difficult.
You have to be VERY familiar with this complex chip to have a prayer of getting it to work.
