[Pratik Singhal]

Hello, I am running ubuntu 15.10 with kernel 4.3.0-040300-generic.
My device id is  Network controller [0280]: Qualcomm Atheros Device
[168c:0041] (rev 20)

I have succesfully copied firmware into
/lib/firmware/ath10k/QCA6174/hw2.1 from the kvalo repository
https://github.com/kvalo/ath10k-firmware

Still, I am getting a error in loading the firmware files , here is
the dmesg log :-

If, I rename the board.bin file in hw2.1/ directory the 2nd error
message is resolved but, where do I get this cal-pci-0000:03:00.0.bin
file ?

How should I resolve this error ?

Thank you,
