Configuration of kernels from 3.13 to 3.16 to support
the Driver
Selection of SDIO modules:
If SDIO module is being used, then ensure that the SDIO stack related modules
are compiled in the kernel. If the SDIO stack modules are not present, then
follow the steps below in order to enable SDIO support in the kernel:
•
Go to the linux kernel source folder. Here it is assumed that the kernel
3.13 is being used as an example.
#cd linux-3.13
•
Run the ‘make menuconfig’ command and make sure that the following
features are enabled in the menu.
o
Select <Device Drivers> and press enter.
o
Press ‘M’ to modularize the ‘MMC/SD/SDIO card support’
feature.
o
Press ‘M’ to modularize the following in the ‘MMC/SD/SDIO
card support’ sub menu.
MMC block device driver
Secure Digital Host Controller Interface Support
SDHCI support on PCI bus
o
Press <Exit> button until you get back to the main menu. Exit
from there too, and save the kernel configuration.
Selection of Wireless Extension Tools:
The wireless extension tools are required in the driver. To check whether the
required modules are enabled, run the script check_wireless_compat.sh that is
present in the release folder. Pass the path to the kernel source as an argument
to the script. The following illustrates an example where the path to the kernel
source is /usr/src/linux-3.13.
# cd /home/rsi/release/
# sh check_wireless_compat.sh /usr/src/linux-3.13/
This script will check for the required configuration options and add those that
are required.
Selection of Bluetooth modules:
If Bluetooth is being used, then ensure that the bluetooth modules are compiled
in the kernel. If the bluetooth modules are not present, then follow the steps
below in order to enable bluetooth support in the kernel:
