You get 64KB of RAM and 256KB of flash.

The stellaris board models ignore the specified -m argument; you
always get the amount of RAM and flash that the real hardware has.
(There is certainly not enough space in the physical address
map to fit a gigabyte of RAM anyway.)

If you want something with more RAM you might try the new-in-2.10
board mps2-an511 which has 16MB of RAM.

Remember that these are models of embedded device systems which
typically have very limited RAM and flash sizes.

[Qemu-discuss] LM3S6965evb RAM size

[Hui Yie Teh]

Hi,

I'm wondering what the default RAM size for the board LM3S6965evb is?

I am trying to increase the size of the RAM using:

*qemu-system-arm -no-reboot -nographic -M lm3s6965evb -m 512M -kernel
o-optimize/test.exe*

and I've tried increasing it to -*m 1G *but I'm still getting errors for my
application for not having enough RAM size.

Any help would be much appreciated.

Cheers,
Yie
