I’m looking for an uploader to push hex files up to the serial bootloader on ATMEGA and similar boards.
File source ideally SD card - push out to serial.
The upload host can be a plain old Arduino with SD for ease of access... target anything that has a serial bootloader.
There are half-assed versions out there, but the ones i found don’t support the larger flash space of the bugger Mega AVR chips (i typically use 1284P chips)
The weakness appears to be the uploaders don’t recognise the embedded address extension markers in the hex files, so they only work on the smaller memory chips- but that’s all.
Any ideas ?
Or do i have to go it alone...?
