Dragonfly Dev board: The removable storage is only 12KB

Hi,

I got the 12 KB removable driver issue on my computer. I know other people were experiencing this issue on the IoT workshop from Multitech. What is the solution to this ??

I got latest ST Link drivers, latest DragonFly firmware as well.

Thanks for you help. Trying to get this DragonFly modem to.... fly again!

Try to unplug the USB then the power. Restore power then USB.

It is an issue with udk.

On Linux debian

  1. df
  2. eject /dev/sdc
  3. eject -t /dev/sdc

The only way I can get 524 Kb is by holding the udk Reset button while connecting the USB. Then I get a 524 Kb removable driver (I am using Windows). I always have DETAILS.TXT, FAIL.TXT and MBED.HTM files in the drive.

The FAIL.TXT contains this error: The interface firmware FAILED to reset/halt the target MCU.

I tried to upgrade the code with DragonFly_Terminal project without success. Can you help ?

Thanks
