Part Number: TDA2EVM5777

Tool/software: Linux

Hi Guys,


We are working TDA2EVM5777, we already got all necessary documents from TI with SDK. But as i have worked sitara & davinci from, i have seen vast amount of wiki pages.

so i would like to know for TDA2xx/TDA2Eco series, TI wiki pages are available or not. As i was in processor.wiki.ti.com i was unable to find. if possible can you share the path.

regards,

Ganesh

    Ganesh,

    TDA2x comes with Vision SDK. Vision SDK is based on u-boot 2014.07 and kernel 3.14:

    Ganesh,

    Make sure you are following VisionSDK_Linux_UserGuide.pdf, it has instructions regarding SD boot and boot arguments (uenv.txt).

    As your questions are moving aways from your subject "wiki link for TDA2EVM5777 is available or not?" I would recommend you to open new e2e thread regarding your new set of questions, ask in the TDAx forum:

    e2e.ti.com/.../1021
