Re: Bricked hardware when updating

What I meant by pressing the reset and pgm button is the sequence that you referenced. It does not enter bootloader mode. In fact the LCD screen has "snow". So is there anyway I can recover from this? Snow sounds like a broken flex ribbon to the LCD. I'm quite sure it does enter the bootloader if y...

Re: Bricked hardware when updating

Many different licenses were used for the DM42 and some of the code can not be open sourced, not our decision.

Re: DM42 License Statement

Studying the code I see that the source code for 100+ functions is not included. Instead such functions are called via hard-coded pointers pointing to addresses inside what seems to be a closed source library loaded at a fixed address in memory. Can't see a way how this can be compatible with the s...
