I’ve noticed that having the external 9V adapter powering the UDK has no effect.. no LEDs are ON with external power only.

This is not the case when using the DragonFly UDK.

Yes it is exactly this part. I’ve removed the mDot from the UDK and still get a 12 Kb drive… so it looks like it’s a UDK only issue right ??

Hi Brandon,

When connected to USB, I got the PWD and D2 leds ON. I can communicate with the mDot using the DB9 port on the UDK fine.

I just tried to connect to a vmWare Windows 7 machine with latest ST Link V2-1 drivers with the exact same result: 12 Kb drive.

I tried two different USB port (one in the back, one in the front panel so that they are using different USB controller), no change.

The drive always contains 3 files: DETAILS.TXT, FAIL.TXT and MBED.HTM. The FAIL.TXT contains: The interface firmware FAILED to reset/halt the target MCU

Hi Jason,

Yes, I tried all the combinations I could think of:

– USB only, power cycle
– USB only connected while RESET button ON
– Power first, then USB
– Power first, then USB while RESET button ON
– Software eject the drive with USB Only
– Software eject the drive with both power and USB connected

Always 12 Kb..
I don’t necessarily need to upload firmware through the removable drive method… I could use the ST Link Utility method IF it is available (just like with the DragonFly), is it the case ???

Thanks,
Jean
