Bootargs in u-boot to using DSP in Beagleboard

Hi all, I want to use DSP in BB Omap3530. I’ ve installed DSP/Link driver and system has booted up correctly. However, when I tried to run sample, system didn’t and it gave the following Warning!

Warning! You need to use mem=126M or less on the kernle cmdline.

You have 240840kB total memory for Linux

How to set bootargs or any like that in boot cmdline to use DSP?

Thanks in advance, best regards…

Thanks for reply, but it is not working. In addition I handle with it.

setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rw rootwait rootdelay=2 mem=80M video=omapfb:vram:2M,vram:4M'
