hi,

can you please provide more details about what you’ve done? How you compiled, which commit, which local changes, … and how you booted the kernel image that you built.

thanks

hi,
I followed the steps as mentioned below.

git clone -n working/qualcomm/kernel.git - Qualcomm Landing Team kernel
cd kernel
git checkout -b kernel-15.06 ubuntu-qcom-dragonboard410c-15.06
export ARCH=arm64
export CROSS_COMPILE=<path to your GCC cross compiler>/aarch64-linux-gnu-
make defconfig
make -j4 Image dtbs

is also same as on mentioned in this link

thanks.

hi ndec,
I did the above mentioned steps to compile the source of linux kernel.and i am compiling WCN36XX as module and load it using insmod but in that case my wifi module probe failed.

[ 1.923745] subsys-pil-tz a21b000.qcom,pronto: wcnss: Memory setup error

while loading the firmware for wcnss module, it gives me Memory Setup error.
i don’t know why it’s giving me Memory setup error.

can you please help me in this.

thanks.

hi,

i just realized there are 2 modules to load to get wlan to work:

insmod /<your module path>/wcn36xx-platform.ko
insmod /<your module path>/wcn36xx.ko

Could that be the problem?

#6

hi,

No, that is not the problem. I have inserted above both modules and test it also. but still it is giving same error.

I have also tested wlan with prebuilt boot image and see it’s kernel log as mentioned.

subsys-pil-tz a21b000.qcom,pronto: wcnss: loading from 0x000000008b600000 to 0x000000008bbe0000

and
my updated kenel log is mentioned below.

Could you help me.

Sorry for commenting on an old thread - I am currently trying to get my wifi chip working and am having some success. However I only have the wcn36xx.ko file present in the lib/modules/version/kernel/drivers/net/wireless/ath/wcn36xx directory. How do I get the platform-tool.ko file to be there so that I can use the board’s wifi chip? Happy to make a new thread if thats the best way forward.

since around ~June release, this module is no longer needed, nor available in our git tree. i think this discussion is going on another thread now, but just wanted to add this clarification here too.
