bootloader pic32mx

[Alkaline]

Hi everyone

is it possible to load the microchip bootloader using mplab x IDE and then load the actual program using flowcode?

the idea is as follows
from location 0 to N load microchip bootloader

from location N+ 1 to M load the flowocode program, as in the attached figure.

Is it theoretically possible to do this?

I ask this because the example bootloader of the microchip allows to update the program via usb (and also in other ways)

If this is not possible, are there other ways to update the mcu flash without using the programmer?

Hello,

Yes this should be possible and we have done so for things like the chipkit devices. There are complications in that you might have to do things like change the address of the linker script so that the project when compiled knows to leave room for the bootloader. e.g. the program starts at 0x1000 instead of 0x0000 based on the size of the bootloader.

The Microchip documentation should hopefully help to get this configured correctly but let us know how you're getting on.

Hello

What I'm trying to do right now is to change the sample bootloader and reprogram it for our demo board.

The procedure is not simple because the software is composed of several parts and I have to understand how correctly they work.

Anyway, in the next days I hope to post some progress!

Dear Ben,
How can I use PIC32MX chips with a simple example?
can you explain?
Thank you

Hello Sadik,

For the PIC32 devices your best bet is probably Microchips Harmony library.
