Can DM8148 (DVRRDK 3.00.01) support 1G memory?

Hi, 

I tried to modify config_512M.bld to support 1G.

But the cfg cannot work when I run ./load.sh.

Can anyone help me to check this file.

Thanks

  • Attached is a config file for 814x that will work for 1G.(Rename to .zip)  Note that you have to ensure your DMM LISA setting is correct to enable 1G access.

  • Can I set the Linux memory to 256MB?

    Thanks

  • To use 256M Linux, reduce 

    SR2_FRAME_BUFFER_SIZE   by 128MB and allocate the freed memory to Linux. You will have to use Linux memory hole configuration

    http://processors.wiki.ti.com/index.php/DM816x_AM389x_PSP_04.00.02.14_Feature_Performance_Guide#Memory_Holes_Configuration

    Make sure you set the address of LINUX_MEM2 correctly by checking the map file.

     

  • DVR RDK uboot is modified to support 512MB configuration. To build for 1GB, you will have do the necessary changes in uboot as well.

  • H,

    Is there any example for u-boot how to modify uboot to 1GB (which works with EVM) ? 
    By the way, why the default setting in u-boot is 512M, while DDR size in EVM is 1GB ?
    If the memory map is for 512M, while DDR is 1G it seems like a waste of memory, isn't it ?
    Thanks,
    Ran
