Hello everyone.

I am in need of a modified boot loader for an arduino Mega 2560.

I would like to be able to update the firmware from a hex file held on an SD card if the file is present at boot time.

I would also like to be able to upload new firmware through the connected LAN interface, a sort of OTA but with the LAN interface.

Please DM me if you are interested in doing this work with your estimated cost for this along with timescale.

Cheers Pete.

There is a bootloader for the Mega with SD support as far as I know. You can dig through these results: arduino mega sd bootloader - Google Search

I have no experience with OTA (wired or wireless).
