Flashing Nodes via DFU

[chrisss]

Hi there,
After successfully naming the nodes anchor 1-6 we tried to flash the nodes using the terminal and dfu 0.9. But the terminal says that the connected device can't be flashed via DFU. The node was powered on with pressed DFU-button.
Hope you guys can help me here.


Best regards
Christian

Hi,
can you screenshot the messages?

Here is the Screenshot:



Edit: The vendorID and the productID are the same as 'dmesg' returns.

Hi,

You can try with adding sudo before the command, the important error there is that dfu-utils is saying "Cannot open device".

Also you are running dfu-util 0.5, the results are not guaranteed (it might work without showing a progress bar). We are running the LPS on Ubuntu 16.04 which has the right version of dfu-utils.

Thanks arnaud. Upgrading and using sudo solved the problem.

I had also experienced such message in Bitcraze V that was up-to-date in all respect when trying to flash the LPS Node. The solution to my problem was that the VM loses connection to the USB device every time it is reset. The error disappeared when I diligently right clicked on the USB symbol in the lower left corner and enabled the newly appeared device, be it bootloader or LPS node.
