Other Parts Discussed in Thread: OMAP3530

Dear all,

I have manged to built the image for omap3530 based gumstix fire SMC and able to run ARM side applications, with the kernel version of 2.6.38. I used openembedded recipes to build it including dsplink, codec engine. The problem is when i tried to run the examples of coded engine on the gumstix target, came across with the following errors:

"CMEMK Error: ioctl(): bad command type 0x9b (should be 0xfe)                  
CMEMK Error: Unknown ioctl received.                                          
CMEM Error: getVersion: Failed to retrieve version from driver: -1.           
CMEM Error: init: major version mismatch between interface and driver.        
CMEM Error:     needs driver version 0x3000000, got 0xffffffff                
@0x00052379:[T:0x4007d000] ti.sdo.ce.examples.apps.image1_copy - main> ti.sdo.y
@0x000525fa:[T:0x4007d000] ti.sdo.ce.examples.apps.image1_copy - App-> Applica.
@0x00052637:[T:0x4007d000] ti.sdo.ce.examples.apps.image1_copy - app done.    
"

One thread discussing this http://old.nabble.com/gstreamer-ti-DSP-and-ioctl-errors-from-CMEMK-td32060561.html, but i have no idea why the latest versions of TI modules cannot work. Please kindly suggest. Thank you.

    Thank you very much, Norman.

    Seems sth wrong with my kernel version. i think it better to put some more info here:

    The output of lsmod:
