Changing bootargs parameters

Hello,

i am able to boot zed board succesfully by following the normal steps.

But for my project i need to use only one core and memory of 112MB of zed board.

When i change the bootargs to,

bootargs = "console=ttyPS0,115200 maxcpus=1 mem=112M@0x0"; in .dts file.

And then created boot.bin and image.ub files.

But now i am not able to boot the zed board.

Is the method i am following is correct??

How to make zedboard to have above mentioned parameters by changing bootrags???

Hi Darshan,

You might have better luck by restricting the memory region definition rather than use bootargs for changing the usable memory space.

ps7_ddr_0: memory@0 {
device_type = "memory";
reg = < 0x0 0x20000000 >;
} ;

Maybe changing this line from 512MB to 128MB space would work for you?

reg = < 0x0 0x8000000 >;

Also, this thread might be interesting to you:

Thanks Kevin Keryk.

I have changed the memory settings and created boot.bin and image.ub files.

When i try to boot,
Instead of blue led (LD12) the green LED (LD9 MI07) is blinking on the board.
I am not able to boot.
What does the LD9 represents ??
