Hello,

can you give an example on the following step from wiki link?

https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/SysLink_Configuration

U-Boot > editenv bootargs
edit: XXXX mem=32M@0xc0000000 mem=64M@0xc4000000 XXXX
U-Boot > saveenv

I am using 256MB DDR memory and plan to split the memory as follow
ARM : 96M
DSP : 160M

Cache = xdc.useModule('ti.sysbios.family.c64p.Cache');
Cache.MAR192_223 = 0x00008000;

i set mine as the following

bootargs=mem=96M@0xc0000000 console=ttyS1,115200n8 mtdparts=nand:128M(rootfs),-(userfs) root=/dev/mtdblock0 rw noatime rootfstype=jffs2

and got this result when running the helloworld

root@mityomapl138:~/ex01_helloworld/debug# ./run.sh
+ ./slaveloader startup DSP server_dsp.xe674
Attached to slave procId 0.
Loading procId 0.
