DVMEGA firmware process doesn't work with 4.0.0-RC3

[AF6VN]

Are you sure you have the proper image also? (I haven't checked if the source was renamed between versions)

Your first post states: Found DVMEGA_RH_V319_UNO.hex firmware...
but the second post: Found DVMEGA_RH_V326_RPI.hex firmware...

The last entries on viewtopic.php?t=243 essentially had the poster reverting to using an actual Arduino UNO to do the flashing.

Thanks Dennis eagle eyed there, i had been trying all different versions just in case.

Will stop trying and go to the UNO method instead.
