I've built LEDE with the ath10K-CT firmware and driver using revision reboot-6553-g9b92afa.
I've loaded this firmware onto 2 separate boards
Gateworks Ventana i.MX6 Dual/Quad GW54XX - Using this as the access point
Gateworks Ventana i.MX6 DualLite/Solo GW53XX - Using this as a client.
Once they are up and connected I start running iperf between the two.
The Client seems to be running stable however the AP crashes shortly after iperf traffic starts.
I've run this test 3 times and for some reason the AP has now stopped loading the driver all together.
