[titan] Cannot load wifi firmware
Branch: titan-wifi
In titan you need to run wcnss-service in order to initialize the wireless interface. I've successfully compiled it getting rid of the Android stuff but I'm still stuck.
After booting and running manually wcnss-service I get the following in dmesg:

[ 119.853924,1] wcnss_wlan fb000000.qcom,wcnss-wlan: Peripheral Loader failed on WCNSS.The first line says it cannot find the wcnss.mdt which is some metadata file for the firmware. This file is available in /lib/firmware. I've also copied the file to other directories like /lib/firmware/postmarketos, /etc/firmware/ and /lib/firmware/postmarketos/wifi but still no luck.
According to Documentation/arm/msm/pil.txt:
User space APIs:
All firmware must be located in the path that is expected by the hotplug (or
compatible) daemon. A hotplug (or compatible) daemon should be running and be
able to handle events from the kernel requesting for a firmware file.
The basename of the firmware files will depend on the peripheral. For a given
peripheral, the metadata filename should end with a ".mdt" and the firmware
segment files should end with ".bXX" where XX denotes the index of the
firmware segment starting from 0.
Android hotplug compatible daemon expects the firmware files to be under
/etc/firmware.
