Make change in Loader for dsPIC33FJ128GP802 MCU

[Ultron]

Hi,
Sorry for the late reply. I've been on vacation.

PPS (peripheral pin select) is a feature on some PIC/dsPIC which allows peripherals to be mapped to different i/o pins. This must be configured properly for the boot loader to work. There is a template prepared for you in user_code.inc.

Which pins do you use for rx and tx?

Ok, thanks for reply!

I have learn on Datasheet the PPS.

Some detail: i have this board, but the Seller does not provide the bootloader of the System:




I have 4 of these cards and I wanted to use them with a normal bootloader.

- The pin for UART are 21 and 22
- Not Crystal, but Internal FRC

My chip is dsPIC33FJ128 GP



I have modified:

Setting.inc with correct MCU line (dsPIC33FJ128GP)
Replaced .gld linker, with correct linker for my dsPIC.

Now I have to enter values ​​for the pins of the UART, in the user_code.inc?
