DSP Link for OMAP-L138

Joe Tijerina

Other Parts Discussed in Thread: OMAP-L138, OMAP3530, OMAPL138

I tried the DSP Link sample application package, instructed on (http://tiexpressdsp.com/index.php/Example_application_using_DSP_Link_on_OMAPL1x), on the OMAP-L138 eXperimenter Kit and it does not seem to work. I'm using the software packages listed on the guide too (MontaVista RFS, OMAPL137 SDK, DSP/BIOS 5.33.05, Code Gen Tools 6.1.9). The software pacakges are labeled for L137, would this same software and setup work for the L138 or is there other L138 specific guides I can reference?

I have gone through this exercise of loading the sample DSP Link app to the L137 and have been successful, but now I get the following error:

# ./unloadmodules.sh
rmmod: can't unload 'dsplinkk': unknown symbol in module, or unknown parameter
# ./loadmodules.sh
insmod: can't insert 'dsplinkk.ko': invalid module format
BusyBox v1.14.4 (2009-10-08 03:10:50 MST) multi-call binary

I do have the same problem with the OMAP3530.

I am using 2.6.29 kernel and dsplink. In the dsplink configuration only the 2.6.18 kernel version is selectable, so I guess the invalid module format comes from different module/kernel versions?

Cheers

Ok now its working. I recompiled the kernel (2.6.29). And then recompiled dsplink (version 1.6, command 'make -s'). The new module dsplinkk.ko is now working and device nod dsplink apears in /dev.
