Which pin(s) do I pullup to reflash mega bootloader?

[dave_sausages]

Hi all,

So I need to reflash my Moteino Mega (long story and not very interesting), and I'm wondering what pins I need to modify to program it.

I've got the LoRa radio module on the board of course and lots of hardware on the other pins.

Do I just need to pullup D4? I've deduced that from this thread where Felix says to pullup D10 on a standard Moteino. https://lowpowerlab.com/forum/index.php/topic,300.msg9832.html#msg9832

Cheers

pullup the SPI CS/SS pin (D4).

Thank you very much. I'm just having a play now.

Oh and if I were to need to change the pin that the LED is on that flashes when being programmed, what is the easiest way to do that? Instead of PD7 I have an external LED on PD5, so I can get a programming status without needing to take my project apart.

Cheers

You would have to recompile the bootloader with the different pin.
