Source Code Modification

This section will guide you how to use the Linux source code. You will see some
examples of using BSP source code in this section. 

3.5.1

Add a Driver to Kernel by menuconfig

You can add a driver to kernel by menuconfig. Here is an example to guide you how
to add a RTC driver (Seiko Instruments S-35390A) to Linux kernel. Please use the
following steps:

1.

Open "Terminal" on Ubuntu 10.04 LTS.

2.

$sudo su 

(Change to “root” authority)

3.

Input user password.

4.

Change directory to BSP's scripts folder.

5.

#. setenv.sh

 (To configure the developing environment automatically)

6.

#./cfg_kernel.sh menuconfig 

7.

Then you will see a GUI screen (Linux Kernel Configuration) as below:
