3.3.2.12.Linux Kernel Configuration
Makefile
Edit the Makefile of the kernel source (
/usr/src/linux-otg ) CROSS_COMPILE path to the path of the cross
compiler
CROSS_COMPILE = /pub/usr/ bin/arm-linux-
The cross compile path ( /usr/include/arm/2.95.3 ) depends on where the tool chain is installed and the
version of the tool chain and from where the tool chain is downloaded.
Kernel Configuration
#cd /usr/src/linux-otg
#make pxa_idp_config
#make oldconfig
Note: For the make oldconfig step accept all the default options. You should use capital letters (N instead of n) to
disable an option, otherwise some weird compile errors will occur.
#make menuconfig
While configuring the kernel, enable the following options:
•
Make the default RAM Disk size (from the options of block device/ Default Ram disk size) to 20480. We are
going to use the RAM disk as mass storage disk space.
•
Enable loopback device support (from block device/loopback device support)
•
Enable SCSI support and SCSI disk support
•
Enable the USB (usb support), USB OTG support and the required USB Class drivers (USB audio, USB mass
storage etc,.) support.
