Hi,

    I am using syslnik_2_10_01_15 version and linux kernel in AM35XX_OM35XX_PSP_LINUX_04.02.00.07.  Using the kernel i mentioned i can able to generate the syslnikk.ko. Using the command insmod  i inserted into the linux kernel. And part from this i got syslink application code from TI. Look at below.

6215.examples_ex02_MessageQ.zip

I followed the instructions in Readme in above examples folder .  According to instructions in the Readme in this folder.

I did  ----> ./run.sh

i got errors . I providing log file .

6675.syslink.txt

In the above firstly you can observe the syslink.ko insertion into the kernel and second sample application execution.

Please help on this.

Thanks

    Does your memory map match that in the cfg/config.bld file - namely this:

    /* Memory Map for ti.platforms.evm3530
     *
     * 8000_0000 - 87FF_FFFF 800_0000 ( 128 MB) External Memory
     * ------------------------------------------------------------------------
     * 8000_0000 - 84FF_FFFF 500_0000 ( 80 MB) Linux
     * 8500_0000 - 85FF_FFFF 100_0000 ( 16 MB) --------
     * 8600_0000 - 860F_FFFF 10_0000 ( 1 MB) SR#0
     * 8610_0000 - 86FF_FFFF F0_0000 ( 15 MB) --------
     * 8700_0000 - 873F_FFFF 40_0000 ( 4 MB) DSP_PROG (code, data)
     * 8740_0000 - 87FF_FFFF C0_0000 ( 12 MB) SR#1
     */

    If so, are you setting MEM=80M on your Linux boot cmd (to reserve memory for the DSP)?

    The errors during 'insmod syslink.ko' are "Not Good", so we should fix those before trying to run the example. You might also enable SysLink trace, which may print more debugging items of interest

    Hi chris,

              In bootargs MEM=248M i set. Then sample applications is working . Does it is correct or  I have to set  only MEM=80M . Memory map is the same above u  said.

    Thanks
