    Hello,

    You could use this command : MACHINE=am57xx-evm bitbake v4l-utils
    After that please check this folder /tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/v4l-utils
    v4l2-ctl you could find here:
    tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/v4l-utils/1.10.1-r0/v4l-utils-1.10.1/utils/v4l2-ctl

    Regarding the steps that you must execute before the MACHINE=am57xx-evm bitbake v4l-utils depends on the PSDK version that you are using. Here is the links to the latest 3 PSDK versions:

    For 5.0 refer this guide software-dl.ti.com/.../Overview.html

    For 4.3 this one: software-dl.ti.com/.../Overview.html

    For 4.2 : processors.wiki.ti.com/.../Processor_SDK_Building_The_SDK

    In all the cases, the last command must be MACHINE=am57xx-evm bitbake v4l-utils instead of arago-core-tisdk-image.

    Hope this helps.

    Best Regards,
    Margarita

    Hello,

    This is my home folder. Your is different but the path tisdk/build... etc is same but you must build the v4l-utils first.

    This is normal you must execute few steps before this command. As I said in my previous answer the steps depends on what is the PSDK that you are building.

    I have provided you the guides to the latest 3 versions.

    In other words, first you must execute the steps from Host Setup chapter. Then you must download and install linaro toolchain (chapter Cross-compile Toolchain). After that follow chapter "Build Steps" but the last command of this chapter must be MACHINE=am57xx-evm bitbake v4l-utils instead of MACHINE=am57xx-evm bitbake arago-core-tisdk-image. If you are behind proxy there is a different chapter for this. 

    Will be better if you let me know the PSDK version that you are using so I could provide you the correct guide for your version.

    Hope this helps.

    BR
