Unable to handle kernel paging request at virtual address

nandish mj

Hello,

I am using DM6467 and dvsdk_2_00_00_22, DSPLink version 1.61.03. I just followed the "UserGuide.pdf" and "InstallGuide_Linux_DM6446_DM6467.pdf" to build dsplink.

my bootargs setting is "bootargs mem=90M" and "bootargs mem=120M"...

With these setting, if I run the sample message application am getting the following error..

Hello,

I was able to resolve this issue.

1. Build kernel with loadable modules which generates "Module.symvers" file.

2. Set the corresponding KERNEL_DIR path in $DSPLINK/make/Rules.mk file.
