How can i set 2G DDR3

kisung cho
Expert 1460 points

Hi,

How can i set 2G DDR3 ?

i checked config_2G.bld(src_bios6/cfg/ti816x/ ) file and read ti install guide.

but m3 is not start.

Pls will you recommand me a  config_2G.bld's bootargs setting? (may i use vmalloc?)

i modified like this.

1. Rules.make DDR_MEM := DDR_MEM_2048M

2. setenv bootargs 'mem=468M

console=ttyO2,115200n8 root=/dev/nfs rw rootfstype=jffs2
nfsroot=192.168.1.200:/home/work/netra/dvr/rfs
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}::eth0:off vram=20M
notifyk.vpssm3_sva=0xBEE00000'

my env is DVRRDK3.0.0.0

    and when i set DDR_MEM := DDR_MEM_2048M , builded u-boot is not work. 

    thus currently i'm using 1024M build u-boot (only change bootargs)

    Thanks.

    Regargs.

    Can you share the config_2G.bld you are using.

    Also have you done memory test on the 2G from uboot to confirm memory is accessible

    Hi Narayanan.

     I attached bld file .

    8080.config_2G.pdf

    This config.bld is incompatible with your your kernel bootargs.

    Config.bld allocates only 128M for linux .

    You will have to modify your bootargs as

    mem=128M mem=340M@0xC0000000

    Are you going for 2G memory map to increase linux size or do you require more frame buffer memory

    HI Narayanan.

    it works good.Thank you. 

    after 2G memory map, UI response time is very fast.

    when i showing the menu, menu display takes 2~3 second previously, but current it takes 0.5 seconds.

    and switching live , playback is more fast.

    I have a another question, 

    340M is used In the second segment .

    is it right that  120M+ 340M memory is used for linux userspace and extra 460M memory is used  for linux kernel space ?

    current my env.

    cat /proc/meminfo 

    MemTotal: 448896 kB

    VmallocTotal: 565248 kB

    The total memory available to linux = 128M + 340 M = 468M. This is for both user + kernel space. Of 468M , 20 M is allocated for vram (for fbdev) so 448M is net available. This is the total lowmem available with usual 3:1 split between user:kernel space.

    Thanks for your answer.

    as you mentioned above, now available memory is 448M ?

    and extra 460M memory is not available?

    when i change "mem=128M mem=440M@0xC0000000" , then there is available memory 548M ? is is right?


    Thank You.

    Regards.

    Yes that is correct.
