Question

Hello

I am trying to use avrdude to flash a microcontroller through the rs232 port on a trb142 with firmware version TRB1_R_00.07.04.3

I have been able to flash it by manually trigging the reset signal but I want to do it automatically

I need to control the DSR and DCD pins which I found to be GPIO pins 949 and 948, there are custom pin mappings in avrdude but it only supports pin numbers 0-255.

Is there any way to remap the GPIO numbers?

Thank you,

Curtis

Hello,

  

Not sure if this is what you are looking for, but a symlink can be created by following this guide.

If this is not the case, could you clarify how the AVRdude is accessing these pins?
