Uploading sketch via USB-to-Serial converter and Serial2

Using Arduino Microcontrollers
1

I have an arduino (atmega2560) based board I have designed and assembled. However the usb to serial element has not worked out for some reason.

In order to check the rest of the board, I would like to be able to load programs onto it. I have managed to do this via another Arduino Uno as a bootloader, but I would like to get the serial feedback.

My question is, before I start trying to tap into the serial0 traces in the PCB, and as I have an existing connection on the board for serial2 tx/rx, is it possible to use this for uploading via an external USB-to-Serial converter?

No, the bootload port is fixed in hardware.

Not as far as I know

Why not upload code using the ICSP header and get Serial feedback on one of the other Serial interfaces ?

4

Yes, or troubleshoot and fix the USB to serial port... why not?

Thanks guys. At least I now know it is not an option. I’ll tap into serial0 rx/tx for now.
Cheers.
