I get the message when writing to OTG/USB (de0-nano-soc)
dwc2 ffb40000.usb Not connected
dwc2 ffb40000.usb Overcurrent change detected
-- then my attached storage is gone till the next reboot
- while investigating i have removed the supply to the USB device & am powering externally
therefore there should be NO over current (current to external device is <100ma so should still not have an issue )
there are no devices being powered off the board - only load is the fpga & support circuitry on the board
(running both processors {linux kernel 4.4.0) , one instance of NIOSII & one of msgdma)
works fine when writing to local SDcard...
next guess is a heating issue - as it seems to function while cold but within 5-10min it fails as above .. ..
any hints ? should i be looking at heatsinks & fans (uuggh) ?
