Tool/software: Linux
I'm using the wl1835 chip debug on the kernel 3.0.35, Android 4.4.2 in imx6.
1. I found the TI web site on the TI: The build script will work with any Linux kernel version > 3.12, using standard backports methodology.
I chose to transplant the backports-3.17.1-1 code separately.
Can I do this, please? Maybe you have better porting steps to guide us on 3.0.35's low - version kernel. Please let me know, thank you.
2. If the direction of my transplant is right, please help solve the following problems.
According to the above steps, I load the compiled wl18xx.ko, wlcore_sdio.ko, wlcore.ko mac80211.ko cfg80211.ko compat.ko driver and have the following error:

I checked repeatedly, no lack of firmware, can not find the location of the method, please help to locate, thank you!
3.Please help to provide the required reference code and the necessary reference documents for the
transplant of wl1835 on our platform.
Thank you!
