I have a problem with QCA9980 initialization.
Hardware/software environment is a TP-Link Archer C2600 with Openwrt
trunk + patches for the c2600. (This device has two QCA9980
controllers for simultaneous dual band operation)
Openwrt is currently populating the firmware files as follows
https://github.com/kvalo/ath10k-firmware/blob/69f955c3dd95d97c7c30960aa5c9852c80b85cc3/QCA99X0/hw2.0/boardData_AR900B_CUS239_5G_v2_001.bin
-> /lib/firmware/ath10k/QCA99X0/hw2.0/board.bin
https://github.com/kvalo/ath10k-firmware/blob/69f955c3dd95d97c7c30960aa5c9852c80b85cc3/QCA99X0/hw2.0/firmware-5.bin_10.4.1.00030-1
-> /lib/firmware/ath10k/QCA99X0/hw2.0/firmware-5.bin
https://www.codeaurora.org/cgit/quic/qsdk/oss/firmware/ath10k-firmware/plain/ath10k/QCA99X0/hw2.0/board-2.bin?id=ddcec9efd245da9365c474f513a855a55f3ac7fe
-> /lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin
Then I am extracting (at hardware initialization time) the appropriate
calibration data from the ART partition on the router flash
offset/count 4096/12064 -> /lib/firmware/ath10k/cal-pci-:01:00.0.bin
offset/count 20480/12064 -> /lib/firmware/ath10k/cal-pci-0001:01:00.0.bin
Using ath10k as shipped with compat-wireless in openwrt trunk out of
the box I get the output in attached nopatch.txt (and wireless is not
functioning clearly)
Using instead the patch from
http://lists.infradead.org/pipermail/ath10k/2015-November/006489.html
Then I get the output in attached patch.txt, and wireless is working
correctly with both radios.
Is it a known problem? Is there a mistake somewhere in how I am
populating /lib/firmware, or is the applied patch the correct fix for
the time being?
Thanks,
Josh
