How to support 1G RAM

xuxianwen · 06-09-2011, 02:42 AM

My development board is Cortex A8 and need support 1G RAM. How to Configure the kernel. I think I need to choose the option of CONFIG_HIGHMEM, but the system didn't work well and bring a kernel panic.
What's I need to do more?

Thanks!
I know how to make menuconfig, but I don't know how to support High Memory in arm-linux

On x86 32-bit systems the kernel supports ~3.3 GB memory without kernel modification.

Did you try to compile a kernel without this option ? Does it works ?
