Problem updating Firmware over USB

[Chrescht]

Hi there,
just received my megadrum minimal Kit from Dmitri.
I sold everything together and plugged MD via the USB to my computer.
Windows recognizes MD and installs drivers. Everything ok. All Pushbuttons and Encoders are working fine.
I use mdfwupdate.exe to update the latest Firmware "megadrum1284_56_20110910".
I put MD as discribed into Update mode and start mdfwupdate.
I select "Megadrum USB MIDI" as input and output ports but then i receive the Message "This application has requested to terminate it in an unusual way" and Megadrum reboots and stays on the VU Meter indications.
If i select other ports nothing happens at all.
I tried it on 2 computers(Vista and Win7)

Also with Megadrum Manager i can not get them to communicate together.

Any ideas?

Thx for your help

How do you start mdfwupdate?

Also with Megadrum Manager i can not get them to communicate together.

This is too little information to give an advice on.

Hi Dmitri,

I put Megadrum in to Update Mode than start mdfwupdate.exe over command prompt like this: mdfwupdate.exe megadrum1284_56_20110910.bin( both files in the same folder)

With Megadrum Manager i configure the midi ports. I used both the same for In and OUT Megadrum MIDI USB(is that right? As i use USB? I have no MIDI connectors connected)
I go to update Firmware put again Megadrum into Update Mode select the same file as above formthenfirmware and start the Update but after a few seconds it says that Megadrum does not respond.
I maybe have to organize another USB cable....
But windows does recognize Megadrum and installs drivers.
Thx

Hi,
will post exactly what you requested:

Step 3:

- Megadrum powered up with left key pressed. Megadrum display shows:

FwSUpdater 16MHz
DOWN-ok.UP-clock

- I select with the UP switch 12Mhz as i have Atmega1248 with 12Mhz.
- I press the DOWN key and Megadrum display shows:

FwSUpdater 12MHz
StartUpdateOnPC

- I run the command line

- I start the command prompt and type:

mdfwupdate.exe megadrum1284_56_20110910.bin

Megadrum firmware update ultility opens to select the ports.

- I select:

Output Port #2: Megadrum USB MIDI

the computer shows in command window:

Openend MIDI Out port 2

- Than i select:

Output Port #1: Megadrum USB MIDI

when i press enter the computer show in the command window:

Opened MIDI In port2.
Firmware file is loaded
Firmware size is 48176 bytes
Transferring.. - 0% done.

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

A Window pops up that mdfwupdate is not working anymore.

Megadrum reboots and the display shows the VU meter.

Hope this helps.
Attached a screenshot of the command windows

Why do you think your Atmega is 12MHz? It is 20MHz.

Thx
It worked.

I was just confused cause on the crystal it is written 12.000...so...my fault, sorry.
After successful firmware update, the MD display shows:

Firmware ver.
20111009 16MHz(Why 16MHz now?)

I can also update the firmware over MDM, it works fine but MDM does always show ?????? for the
firmware version.
When i load settings from MD the LED comes on, so there is comunication....i suppose
but there are no changes in MDM. Same for sending to MD. No changes.

Did i missed again something?

Thx

When i hit my snare, MD VU shows the input.
MDM shows nothing in MIDI Log

Does it show 16MHz after power cycling? If it does, load the firmware from viewtopic.php?p=19002#p19002 and and tell me the number it shows on the first screen of the menu after power cycling and entering the menu.
