problem installing c6ezrun

Radhika,

This looks like it might be an issue with the path to the ARM compiler.  Since building the DSP-side backend library does not use the ARM compiler, this would explain why you don't see an issue there.  I would start by checking the Rules.mak file to verify the settings you have there.

If everything looks good there, then we might have to trace the chain of Makefiles to see if we can pinpoint exactly where things go wrong (though based on the above, it appears to be where the DSPLink ARM libraries get built).

Hi,
   I was able to install c6run. There was problem in the path of Rules.mak.
But I am not able to run the dsp examples on the Beagleboard.
I compiled the examples using "make examples" and loaded the neessary kernel modules and the
scripts on the target file system.

I loaded the kernel modules.

But the arm code runs fine.

What could be the reason ? Why am I not able to run the dsp code ?

Hi:

    I was installing the C6Run for my Devkit8000 OMAP3530 board.

    I've downloaded the C6Run_0_97_03_03。And I've edited the Rules.mak and platform.mak file. when I excute "make dsp_libs" and "make gpp_libs", there's no problem. But when I excute the "make modules", it has error, which is "gpp/src/arch/OMAP3530/shmem/Linux/omap3530_phy_shmem.c:132: error: 'SZ_2K' undeclared (first use in this function)".

    How to I sovle this problem?

    Thanks a lot.

For some strange reason, there were some kernel versions (2.6.29 and 2.6.30 I think) whose source was missing that particular #define in the kernel headers.

See here: http://permalink.gmane.org/gmane.linux.distributions.gumstix.general/54076

A quick workaround is to add that #define to the arch/arm/include/asm/size.h file in the kernel source tree.
