OMAP L138 LCDK HelloWorld sample program errors

Other Parts Discussed in Thread: OMAPL138, OMAP-L137

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

    I think you need to address the first errors:

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

    You need to load DSPLINK with

    insmod dsplinkk.ko

    Hi Norman,

    I entered insmod dsplinkk.ko

    I got this

    Error: could not insert module dsplinkk.ko: Invalid module format

    I don't know how to insert this module? And how to get the right module format?

    It has been a while since I dealt with those error messages.

    - You should use the same ARM cross-compiler to compile the kernel, DSPLINK and your application.

    - The DSPLINK kernel loadable module has to be built against the same kernel version that is on the target.

    - How are you getting your compiled code onto your target? Is is unlikely but maybe your images are getting currupted in transit.

    Hi David,

    Norman suspect ion was right.

    I entered insmod dsplinkk.ko

    I got this

    Error: could not insert module dsplinkk.ko: Invalid module format

    I don't know how to insert this module? And how to get the right module format?

    Where did you insert the "dsplink.ko" module ?

    Are you trying to insert it in linux host PC ?

    You have to insert the driver in OMAPL138 LCDK board and you have to execute "./HelloWorld HelloWorldDSP.out" in LCDK board and not in linux host PC.

    I followed the DSP HelloWorld example. All commands are in LCDK board!
