DM814x default Filesystem images

Hello,

Where can get the default Filesystem images (rootfs-base.jffs2, ubi.img or nfs.tar.gz) for DM814x?

Thanks very much,

Jian

  • Hi Jian,

    Dowload the EZSDK for DM814x and install the same, steps and download location can be found here: http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html

    Once the EZSDK is installed, you can find the directory named "filesystem" with tar.gz file of fs using which you can generate .jjfs2 fs.

    Command: mkfs.jffs2 -p -d rootfs -s 2048 -e 0x20000 -l -q -o rootfs.jffs2  -v –n

    Hope this helps.

  • Hi,

    You can download the TI EZSDK here ->http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html  and install the same on the Ubuntu 10.04 machine. This installation has a tar of filesystem.

  • Hi N.S.SriHarsha and Vijay

    Thank you very much for your help.

    I downloaded and installed TI EZSDK and CodeSourcery GCC Toolchain. I can find there are two ezsdk-dm814x-evm-rootfs.tar.gz and arago-base-tisdk-image-dm814x-evm.tar.gz.

    I use ezsdk-dm814x-evm-rootfs.tar.gz to creat rootfs.jffs2. But it is too big for the NAND to use when booting.

    Since my main target is to verify if the touch screen controller works fine on my DM814x board using the linux touch screen driver.  I only want to include the necessary elements in the filesystem.  Could you please let me know how can I do next to creat a small size filesystem? and what are the necessary elements that I should include in?

    I have another question about setting Up Boot Environment on SD Card.  Could you please give me some help?

    When I used the default TI SD with the DM814x Board, I got  VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2)" errors. Is there some method that to recover it or create a new bootable SD?  I did the below steps try to creat a new SD, but it doesn't work. I used "MLO, u-boot.bin and uImage-dm814x-evm.bin" from TI EZSDK board/support/prebuilt-image and ezsdk-dm814x-evm-rootfs.tar.gz from filesystem. I inserted a 4G sd card and ran " sudo ./mksd-ti814x.sh  /dev/sdc MLO u-boot.bin uImage-dm814x-evm.bin ezsdk-dm814x-evm-rootfs.tar.gz ". 

    Thanks a lot,

    Jian
