    Hi,

    Which version is your VisionSDK?
    Do you see any output on the UART console?

    Hi,

    after you install the PROCESSOR_SDK_VISION_03_01_00_00_setuplinux.bin, please follow instructions in docs/Linux/VisionSDK_Linux_UserGuide.pdf.

    First you need to prepare your setup according to "2.4 Software Installation & Setup" (this includes cloning kernel, U-boot, vsdk patches etc.)
    Then you must build the SDK according to chapter "3. Build".
    After that you can prepare your SD card according to chapter "4.2 Preparing SD card & Boot" and test it with the steps described in "4.3 Run demos"

    HI Yordan
    Thanks for your device,but i have a question,in 2.4.2.1,this

    "$> git am ../linux-kernel-addon/kernel-patches/*
    memcahe.ko source
    There is additional kernel module needed for vision_sdk, ensure the source lies
    under $INSTALL_DIR/ti_components/os_tools/linux/kernel/linux-kerneladdon/memcache, this comes by default with installation"

    i did not find the memcahe.ko why?
    thanks again

    Hi,

    do you see any errors while you run "git am ../linux-kernel-addon/kernel-patches/*" command?
    Do you have any files in $INSTALL_DIR/ti_components/os_tools/linux/kernel/linux-kerneladdon/memcache directory?
    The memcahe.ko should be generated when you build the kernel.

    Regards,
    Yordan
