Wow, that was fast! The SourceForge USBDM project has added support for MCU10.4 (see as well this post) in release 4.10.5 available here, announced in the Freescale Forum.

Installation is easy (uninstall a earlier version might be necessary). As for 10.4, make sure you browse to your installation folder (it was not able to find my 10.4 installed version in the default C:\Freescale\CW MCU v10.4\ path:

Then make sure you launch Eclipse with the -clean option (or from the shortcut installed) after installation:

However, although the USBDM device was properly showing up in the device manager, and as well in the debugger settings, I was not able to connect:

From the connection settings everything was looking ok:

Still, I had errors:

New USBDM Firmware

Reading the release notes, it tells that the OpenSDA USBDM supports USB CDC (similar to the P&E OpenSDA CDC), so I thought that there must be a new USBDM firmware. And I found it here:

C:\Program Files (x86)\pgo\USBDM 4.10.5\FlashImages\MKxx\USBDM_OpenSDA.sx

Programmed the board with the new firmware. However, this did not not help :-(.

Uninstalling and Re-installing USBDM Device Drivers

Next thing to try was to uninstall the USBDM Drivers, as I would have expected that a USB CDC device would enumerate as virtual COM port. Obviously this would need new device drivers. So I uninstalled the existing drivers and installed the new ones. And indeed: now USBDM shows up as a composite (multi-role) device:

And it enumerates sucessfully as an USBDM Serial Port:

Good news: with this I should have USB CDC support as with the original P&E OpenSDA. Bad news: I’m still not able to connect to my board 😦

I uninstalled the USBDM drivers, installed a clean CodeWarrior for MCU10.4, re-installed USBDM and all the drivers. But still: not able to connect to my board.

Puzzled with that, I re-installed the original P&E USBDM firmware, and I was able to connect to the board. Then flashed again the USBDM firmware, tried with USBDM, and: it worked! 🙂

I’m really not sure what the problem is/was. All what I can say is that I was working with low power modes on that board, and it could be that the microprocessor was in a low power (stop, I think) mode, and somehow OSBDM failed to connect to it. I have made so many desperate changes, that I’m not sure any more what was originally on the board. But at least I was able to connect to it with the original OpenSDA.

Summary

USBDM supports new CodeWarrior for MCU10.4. The wizard integration works out of the box, and even a problem I have seen with the earlier 4.10.4 version disappears with the new version. USBDM has added USB CDC support which is a great thing. Until I’m able to reproduce my (potential low power mode) problem, I recommend to use the original OpenSDA firmware in case connecting to the board does not work. Other than that: USBDM works very well for me.

Happy Debugging 🙂
