OMAP L138 LCDK HelloWorld sample program errors

i had my HelloWorld program installed on my OMAO L138 LCDK. After I entered ./HelloWorld HelloWorldDSP.out (from my Linux Host PC serial port terminal)

I got

Loading file HelloWorldDSP.out

dsplink driver open: /dev/dsplink: No such file or directory

Error running PROC_setup : 0x80008008

Starting application.

Assertion failed (((drvObj != NULL) && (IS_OBJECT_VALID (drvObj, SIGN_DRV))) || ((drvObj == NULL) && (cmdId == CMD_PROC_ATTACH))). File : drv_api.c Line : 501

Msgq <GPPMSGQ1> open: 0x80008002

AND CONTINUE THIS

Assertion failed (MSGQ_isLocalQueue (msgqQueue)). File : msgq.c Line : 641 error...

What was the cause?

i enter uname -r on my LCDK, it shows 3.1.10 ... However, uname -r on my linux host pc is 2.6.32-53-generic-pae
Is this something wrong too?

Thank you,

David
