I downloaded the 23.5.A.1.291 kernel source from sony open devices archive and tried to compile it without any modifications. There were some warnings but i was able to compile it. Usb otg and wifi wasnt working when i flashed it. Is there any config file with the correct configuration ?
The details shinano_sirius_defconfig doesnot have any line mentioning wifi module .
I then compiled the bcmdhd as a module and the file bcmdhd.ko was 4.9 mb in size whereas the stock file was around 650kb. But copying that file to modules made the wifi work on reboot. But i cannot turn off an on the wifi. The usb otg was also not working.
