Hello,
I am trying to get a custom kernel + initrd working for porting InkBox OS (https://inkbox.ddns.net) to the Kindle Touch.
So far, it boots, loads the initrd fine, I can get a console prompt, the FB driver apparently needs a better waveform (things printed on the display show up as distorted).
I am now to the point of loading the Wi-Fi module and driver and it just doesn't work.
This will give a better explanation:
The firmware file is there and the symlink points to the right place, but apparently the driver doesn't want to load. The only thing I changed in the code was to change the location of the firmware from /opt/ar6k to /mnt/lib/firmware/ar6k. As you see, it's trying to load it from the correct location, but that doesn't work.
I don't get any wlan0 interface either.
Loaded modules:
I joined the complete boot log in case someone wants to have a look at it.
The complete source for the driver is here: https://github.com/Kobo-InkBox/kerne...ireless/ar6003
In case why you're wondering why the version shows up as 2.6.35 while it's supposed to be 2.6.31... let's quote myself from a related commit in my InkBox kernel repo:
I kinda feel guilty, but anyways... :D
Thanks and I hope someone has an answer... Luck + Wi-Fi drivers isn't a thing for me...

In case why you're wondering why the version shows up as 2.6.35 while it's supposed to be 2.6.31... let's quote myself from a related commit in my InkBox kernel repo:
Code:
The kernel sources were taken from Amazon's website at https://kindle.s3.amazonaws.com/Kindle_src_5.3.7.3_2715280002.tar.gz . When compiled and executed, it will display '2.6.35' as its version number, but it is in fact a 2.6.31 kernel. The reason for this hackery is that the glibc chroots in InkBox OS don't support 2.6.31 kernels, but do support 2.6.35.x ones. Changing the version number in the kernel Makefile seemed to do the job fine, and I haven't seen any problems in using glibc binaries and libraries, they all run fine with this new 'patch'.Thanks and I hope someone has an answer... Luck + Wi-Fi drivers isn't a thing for me...
