[OMAPL137] Linux Startup Warning & FATAL error

Other Parts Discussed in Thread: OMAP-L137

I upgraded my MVL linux on my OMAP-L137 evm board with the latest OMAPL137 1_00_00_11.

Now, I got warning/FATAL message when I start up the board:

....

WARNING: Couldn't open directory /lib/modules/2.6.18_pro500-da830_omapl137_evm-arm_v5t_le: No such file or directory
FATAL: Could not open /lib/modules/2.6.18_pro500-da830_omapl137_evm-arm_v5t_le/modules.dep.temp for writing: No such file or directory

....

Do I need to populate these folders? What should I put them?

Thanks,

Davidz

    Hi David,

    Did you follow the sequence:

    make ...
    make... modules_install
    make... install

    according to the specific section of the GSG?

    Mariana,

    Thank you for your quick response.

    I followed the step per the specific section of the GSG as you suggested. I got the make error:

    make: *** No rule to make target 'modules'. Stop.

    make: *** No rule to make target 'modules_install'. Stop.

    Can you tell me what are these modules for?

    Thanks,

    Davidz

    Davidz,

    This error indicates that there is no 'modules' section in the makefile.  Are you in the correct directory (ti-davinci/linux-2.6.18_pro500 )?  Also, make sure that you have followed every step in the GSG and there are no typos.  Which command are you running when you get the error?

    David,

    Thank you for the response. I did missed a step in the GSG instruction. I was not in the correct directory.

    It works OK now.

    Thanks

    Hi Mariana,

    I don't know whats wrong with my net, i cannot post my question on the support, so I only write my question here.

    Now  I use omapl173 chip, but several problems have not  been cleared:

     First, in omapl137 ,what is the relationship between the dsp core and arm core in the end.

     

     

     Second, do the arm core  and dsp core share the same data memory and program memory,and how they coordinate to control these memory address?

     Third, how dose the two cores  communication ,and how s the dsplink works, as well as those peripherals, could only the dsp core control the peripheral or both the two cores could control them?

    Thanks very much!

    Hello,

    Have you had a look at http://processors.wiki.ti.com/index.php/Category:DSPLink There are answers to your questions like how DSPLink provides IPC to communicate between the two cores and how it works.

    DSPLink does not control any peripherals. Which peripheral are you interested in? The h/w spec will tell further details whether ARM/DSP can control it.
