It looks like you have a communication problem between USB PIC MCU and Atmega MCU on the board.

The board is a two layer all in one PCB V2.8 by Synthex. Everything on the board looks normal. What else could be done?
Build a new one?

It can also be crystals frequency mis-match but I understand the board was working fine before so I presume it can be only PIC<->Atmega communication problem on the board.

I will order arm based lite kit in the future and use this one as is for simpler projects. It still works as a midi trigger module, just can't update or work with MDManager. Thank you dmitri for your time.

I purchased megadrum maybe 2 years ago and have not been able to get it to work. I can get to step 4 with a command line and type in the correct information for windows "mdfwupdate.exe megadrumSTM32d_56_20181218.bin" and cannot get to step 5. It says mdfwupdate.exe is not an operable program or batch file.

You're not running the command from the directory where mdfwupdate.exe is located.
