With the original linux installed on my Beaglebone Black the scope worked but then I installed a newer debian version with a 4.1.22 kernel and now I keep getting an error with scope power:
dwfcmd analoginout.txt
FAILED: FDwfDeviceOpen
The device needs at least 2W/400mA from USB cable. To satisfy this:
- Try to use different USB cable and computer plug.
- Use the USB plug on the back of the PC, not the one on the front panel.
- Use short cable, do not use long cable or cable extender.
- Use powered USB-hub, avoid un-powered hub.
- Use 5V auxiliary power supply.
USB: 0.01V 777mA AUX: 3.58V 580mA
The Analog Discovery 2 has its own 5V power supply and I use the original cable I don't see a reason why this shouldn't work.
Anyone with the same problem or a solution out there?
