    Hi,

    I build Linux using Timesys Linuxlink for Omap3530 SOM-LV. I have the output file "uImage-2.6.28-ts-armv7l" , "rootfs.tar", uboot and the other files(except factory.tar.gz as this is not a free file, What is this factory.tar.gz used for?)

    I want to make a bootable SD card to start Linux and not from TFTP server(which the doc tells in the website). Can somebody tell me the steps I need to follow to start the linux on my device? How to install the software sources and packages included in the build output.

    Please help me out. Thank you in advance.

    Hi ,

    you need a boot and a normal partition in your sd card.
    repartition and format it . Then copy u-boot and uImage to boot partition. Extract root filesystem in 2nd partion.
    you must be root for all above things.

    And if you are using Lolo as boot loader , write a script there to exec and load u-boot from sdcard.
    From u-boot prompt change bootargs to load uImage from sdcard and set kernel parameters.

    Thank you for the reply.

    What if I do not need to use the LoLo as the Boot-loader and instead want to use x-loader. Which file I will need for X-loader and where can I get that file?

    What steps I need to follow then?

    Also for the Lolo as the Boot-loader, Can you tell me How can I learn to write the Script which will load the u-boot from the SD card? Can you tell me the Script for loading and running u-boot.bin?

    I did what you said but after reading the kernel image "uImage-2.6.28-ts-armv7l", it hangs up and nothing appear. The last message I got was "Uncompressing the Kernel.......Done"

    What should I do now?What can be the problem?

    Pcdash,

    If I Use the uImage supplied by the LogicPd. Can I still use the RFS (rootfs.tar.gz) generated by Timesys with this uImage? The packages which I chose while making the workorder in Timesys will be in RFS, right?

    Pcdash,

    I changed my bootargs from console=ttyS2 to console=ttyS0 and I was able to see the kernel booting. Now How can I start my display as right now nothing appears on my display?

    Also, I want to write a code for my application. What will be a good way to move forward for my application? I mean should I use Timestorm IDE to write my code? How should I compile it? And where do i need to put the executable file in the OMAP device?

    Thanks a ton for helping me out.
