I need to do some modification on the wifi driver.
I have tried to cross compile the driver downloaded from GitHub - 01org/edison-bcm43340. After compilation, I can insmod this driver. However, it does not work correctly after insmod. I have also tried to add a kernel patch according to the Yocto Project Manual. But I can not find where to generate the patch for bcm43340.
Can anyone provide the correct process to modify the wifi driver?
If you need help modifying the bcm43340 driver I’d suggest you to contact Broadcom https://community.broadcom.com/welcome . Broadcom developed this driver so that it could be used with the Edison so they’ll be able to provide a more accurate response.
