Hey Dmitri!
Just got my MegaDrum, and it has a FW from 2011.
I believe I have AT644 board. I know I am limited with future updates, but I can not find a way to update to the newest firmware.

I am running OSX 10.11.6.
I have the megadrum644_48_20160529 FW downloaded.
I have downloaded both, Mega Drum Manager, and mdfwupdate

Attached are the screens that I believe are relevant.
I have tried setting my MIDI to be the same port, and different ports, 1 and 2.

As per http://www.megadrum.info/forums/viewtop ... f=3&t=1252 describe step by step what you do and what happens.

I mean... I've read that. and I'm not sure what step I'm missing.

I don't have text on the LCD of the MD.
I've watched some videos, and when I open the mdfwupdate, i don't get any options...

What am I doing wrong?

Well, that means you don't follow the instructions from http://www.megadrum.info/forums/viewtop ... f=3&t=1252 exactly. As I suggested, describe step by step what you do and what happens.

I am trying my best to follow the directions!
here's a video of my setup.
Can you please tell me what I'm missing?!

Thank you!

If firmware upgrade doesn't work in MDM for some reason, follow http://www.megadrum.info/forums/viewtop ... f=3&t=1252 - it always works. I don't see from the video that you use mdfwupdate.

Here's what happens when I use the uploader.

What step am I missing?!

In step 4 of http://www.megadrum.info/forums/viewtop ... f=3&t=1252 it says:

4. From a command line run the utility, e.g. on Windows:

mdfwupdate.exe megadrum644_20111213.bin

On Mac OS X;

./mdfwupdate megadrum644_20111213.bin

You run it not from a command line.

Hey Dmitri!
I finally got passed the hiccup.


and then this happened:

There are 7 MIDI output ports available.
Output Port #1: IAC1 Bus 1
Output Port #2: IAC1 IAC Bus 2
Output Port #3: IAC1 IAC Bus 3
Output Port #4: IAC1 IAC Bus 4
Output Port #5: MegaDrum USB MIDI Port 1
Output Port #6: MegaDrum USB MIDI Port 2
Output Port #7: TouchOSC Bridge

Select an output port number for the firmware update (between 1 and 7):5

Opened MIDI Out port 5 .

Any input on this?
Thanks!

Possible causes:
1. You have other (MIDI) programs running at the same time that open all available MIDI ports, including MegaDRum MIDI ports. It will interfere with firmware upgrade.
2. The main board has a hardware fault where PIC USB chip and Atmega644 chip have a problem with serial connection between them.
