I run a QN9080DK-V1.2 with switched DFU modeconnected to a Windows host. All development work is done within an Ubuntu Virtual Machine (VMware) 16.04.1 with kernel 4.13.0-39


I got mcuexpresso installed, imported the right SDK and got an example compiled. Trying to start a debug session fails.

First after clicking "Debug 'qn908xcdk_wireless_example...'" results in a question dialog "Boot Redlink" for USB Device 0x1fc9:000c

Confirmed with yes, probe discovering is started but failing.


"sudo lsusb -v -s 0001:0006" confirms, that device has been loaded correctly, since the divece has changed:

 idVendor 0x1fc9 NXP Semiconductors
idProduct 0x0090
bcdDevice 1.00
iManufacturer 1 NXP Semiconductors
iProduct 2 LPC-LINK2 CMSIS-DAP V5.183
iSerial 3 GSA1BQHQ

In MCUexpresso the console just tells, that RedlinkServer has started and immediatly closed again.


What has to be done to get the Probe Discovery passing and get a working debug connection to the DK board?
