How to config ELF format using C6RUN for OMAPL137?

I would try to see if you can run the SysLink stand-alone examples on your device first before attempting to run C6Run.  Information on how to build/run SysLink can be found at: http://processors.wiki.ti.com/index.php/SysLink_Install_Guide_-_2.00_and_2.10

There are newer version of SysLink available than the one you are using though it unsure how newer version of SysLink may interact with C6Run.

NOTE: The C6Run package is no longer being supported (see http://processors.wiki.ti.com/index.php/C6EZRun.

The alternative is to leverage SysLink directly which C6Run was using underneath. The example should be a good starting point for this.

Hi,Arnie

Thanks for your reply. I knew there are newer verisons of syslink.But when I use syslink 2.20 plus and make syslink.ko module,it can not be inserted to Linux kernel.The error code is :

Syslink: Unknown symbol irq_to_desc
insmod: cannot insert 'syslink_latest.ko': Unknown symbol in module (-1): No such file or directory

Does that has something to do with my linux kernel  2.6.33？

I have also tried to build a c6run helloworld example using omapl137_syslink_config,here's the output of syslink.ko after running:

Any ideas about this? Thanks in advance.

Does that has something to do with my linux kernel  2.6.33？

The newer versions on SysLink call into the irq_to_desc function when using a kernel version less than 2.6.37.  This was added to fix a double IRQ issue to improve performance. In some cases, this function isn't being exported by older kernels.  The function is defined in $KERNEL_DIR/kernel/irq/handle.c.  You may be able to simply add:

EXPORT_SYMBOL(irq_to_desc);

in that file.  You'll have to re-build the kernel for this to take effect.

BTW: Though the latest SysLink version will work on older kernels, its has been validated on the 2.6.37 kernel.

I'm not sure what exactly is going on here as I'm not familiar with all the C6Run build structure.  Could it be that the DSP binary is built in COFF format were as SysLink expects it in ELF?

Have you tried building and running the SysLink sample/example applications?  This will ensure that SysLink is working properly on your setup.  Just follow the instructions in the SysLink Install Guide.  Make sure you are referring the correct Install Guide based on the version of SysLink you are using.

Hi,Reynoso,

I used EXPORT_SYMBOL(irq_to_desc) as you said and solved the syslink module inserting problem.Now I can insert syslink2.2 ko module into my 2.6.33 linux kernel.However the omapl137 elf format still cannot work...I have another omapl138 board and easily get it work with syslink2.2 and c6run in elf format.

So my question is:

1.Have you ever had experience of testing syslink on omapl137? There seem to be no syslink examples designed for omapl137.

2.Can omapl137 support higher version of linux kernel? Now the 2.6.33 version seems to be latest for it.

Thanks !

SysLink releases have only been validated on an OMAP-L138.

I'm not sure.  Others on the forum may be able to confirm this.  You may benefit in posting a new post asking this specific question.
