Hi TI E2E Community,
I am now using OMAPL138 evaluation board for our project. Now I have run the syslink_2_21_03_11 ex02_messageq examples.when dsp and host are running,I enter "CTRL+C" to force the host process to exit and then the linux kernel was aborted.Here are some exception information:
root@omapl138-lcdk:/ex02_messageq/release# ./run.sh

Attached to slave procId 0.
Loading procId 0.
Loaded file server_dsp.xe674 on slave procId 0.

+ ./app_host DSP
