Hi,
I am using OMAP-L138 LCDK.I need to use UART0 and UART1 in my application to be be ableto perform this I needed to change some lines in arch\arm\mach-davinci\board-omapl138-lcdk.c.
Until now,everything is OK.But I am new to Linux environment and I do not know how to change my LCDK's old kernel with the new one.
Can you help me on this?
Thanks,

Hi user,
If you are new to the Linux environment, then you have to first setup the work environment ready for building Linux.
You can use the OMAPL138 LINUX SDK which encloses everything like u-boot, Linux, filesystem and pre-built images etc.
Follow the getting started guide below to install the SDK.
If you want to directly just rebuild the kernel,
Export the tool chain path and verify that it is updated.
host $ export PATH=$HOME/<Tool_Chain_directory>/bin:$PATH
host $ echo $PATH ---> observe the output.
host $ cd linux-3.1.10 [ Go to your Linux source directory and make modifications. ]
host $ ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- make distclean
host $ ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- make omapl138_lcdk_defconfig
host $ ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- make menuconfig [To enable / disable drivers.. You can skip this step if not needed.]
host $ ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- make uImage

Hi,
I cross compiled in my host machine and get the response; Image arch/arm/boot/uImage is ready.
So,to be able to work this kernel in my LCDK where should I copy this uImage file? Is it the only file that I should change in my LCDK
Thanks,
