DaVinci PSP 03.01 GA Release (Build r37) on DM6446

Other Parts Discussed in Thread: TVP5146

Hi all,

 

I am a little confused by my question but I have seen the release 37 from TI which is perfect for you.

So I tried to use it on my DM6446EVM from Spectrum Digital without success about the display.

I have tried the binaries provided and tried to recompile the kernel, same result, nothing.

This release works for this platform but when I tried to use the dmai examples, I have a message error that indicates the system can open display.

Is it a problem from my bootargs or something wrong in the release ?

Thanks for your help.

    Hi,

    It looks like u have not build your kernel with proper configuration .

    Recompile your kernel with "make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-  davinci_dm644x_defconfig"   and check.

    Regards,

    kirti.

    Hi,

    There is no davinci_dm644x_defconfig file in arch/arm/configs, only davinci_all_defconfig.

    To be more explicit, please read the message after a test with encode from DVSDK

    ./encode -k -v test.mpeg4 -o

    Can you just run a  display application and try to figure out the issue?

    It's done but nothing to display.
