RTOS/AM5728: undefined reference to 'ti_sysbios_family_arm_a15_cache_xxxx_E' when enabling smp

Part Number: AM5728

Tool/software: TI-RTOS

Hi

I want to enable smp in my project ‘vps_loopbackExample_evmAM572x_armExampleProject’, but some building errors occurred after i modified some codes in main.cfg.

codes about smp in my cfg:

var BIOS    = xdc.useModule('ti.sysbios.BIOS');
BIOS.smpEnabled = true;
var Core = xdc.useModule('ti.sysbios.family.arm.a15.smp.Core');
Core.useSkernelCmd = false; /* Set to false if running in CCS and using gel files to wake-up secondary cores */
Core.numCores = 2;
var Cache = xdc.useModule('ti.sysbios.family.arm.a15.smp.Cache');

I also added 'BSP_OSAL_SMP_MODE_ENABLE' in my project

ccs building errors:

is something missed in my .cfg or project?

    Do you have the following in the .cfg file:
    /* Load the OSAL package */
    var osType = "tirtos"
    var Osal = xdc.useModule('ti.osal.Settings');
    Osal.osType = osType;

    Thank you for reply in holidays.

    Actually, i enabled smp mode in 'bspCommonBIOS_a15.cfg' of the project 'vps_loopbackExample_evmAM572x_armExampleProject' under C:\ti\pdk_am57xx_1_0_12\packages\MyExampleProjects, the osal lib is loaded in the bspCommonBIOS_a15.cfg as you wrote. but i think the problem is that smp has not been enabled in the osal and edma3 lib when build.

    look at these building log, errors locate in three aa15fg:

    1.vps_osal_tirtos.aa15fg(bsp_osal.oa15fg):

    2.edma3_lld_drv_sample.aa15fg(sample_arm_cs.oa15fg):

    3.ti.osal.aa15fg(CacheP_tirtos.oa15fg): 

    For the lib vps_osal_tirtos.aa15fg(bsp_osal.oa15fg), i found a makefile under 'C:\ti\pdk_am57xx_1_0_12\packages\ti\drv\vps\src\osal\tirtos\smp', so i build it then get vps_osal_tirtos_smp.aa15fg under '\packages\ti\drv\vps\lib\am572x\a15\release'. I replaced the 'vps_osal_tirtos.aa15fg' with 'vps_osal_tirtos_smp.aa15fg' in my project and the first 2 link errors were solved.

    So I think the problem is the same for other link errors. but the problem is that i can't find any makefile which can enable smp mode like 'packages\ti\drv\vps\src\osal\tirtos\smp' for edma3_lld_drv_sample.aa15fg and ti.osal.aa15fg(CacheP_tirtos.oa15fg), Could some ti expert supply the smp version makefile for edma3 and osal for me to build edma3_lld_drv_sample_smp.aa15fg and ti.osal_smp.aa15fg like vps_osal_tirtos_smp.aa15fg?

    smp version of osal and edma3 lib is needed.

    Hi
    Thank you for reply. but my problem is a little different with the case in your link. My building error occurred when enabling smp in vps_lookback project, and i analyzed these errors as above. I think you team should supply the smp version makefile for edma3 and osal for me to build edma3_lld_drv_sample_smp.aa15fg and ti.osal_smp.aa15fg like vps_osal_tirtos_smp.aa15fg.

    Shreek,

    I can reproduce your build error when change this project into SMP. There is no SMP makefile for edma3_lld_drv_sample_smp.aa15fg and ti.osal_smp.aa15fg with SMP. Let me check how those cache functions can't be found in the linking stage.

    Hi,

    From the failure log, the application linked with several libraries. Some of the libraries source code contains the cache operation, e.g.
    - bsp_osal.c, line 1106, it has Cache_inv()
    - sample_arm_cs.c, line 255, it has Cache_inv().

    Those two files include a header file called #include <ti/sysbios/family/arm/a15/Cache.h>. Those libraries are not pre-built with SMP support. I think they have to be rebuild with SMP support, that is in the source code change the include header to:
    #include <ti/sysbios/family/arm/a15/smp/Cache.h> and rebuild the libraries.

    Unfortunately there is no such makefile for this. You may change the header and rebuilds the libraries.

    Regards, Eric

    Thanks. It seems that rebuilding the library by replacing #include <ti/sysbios/family/arm/a15/Cache.h> with #include <ti/sysbios/family/arm/a15/smp/Cache.h> in some source files is the only way. I 'll try. But it will be so complicated if the another project is using the smp-disabled librarys.

    Now the question is how to build edma3 after adding '#include <ti/sysbios/family/arm/a15/smp/Cache.h> ' in sample_cs.c under 'C:\ti\edma3_lld_2_12_05_30C\packages\ti\sdo\edma3\drv\sample\src'.

    Shreek,

    Please check the user guide under edma3_lld_2_12_05_30C\packages\ti\sdo\edma3\drv\docs. Section 2.4. This will create different libraries with cache or smp cache, and your application need to manage which library to link with.

    An easier way I tried,
    - add edma3_lld_2_12_05_30C\packages\ti\sdo\edma3\drv\sample\src\sample_arm_cs.c to your CCS project, add a line:
    #include <ti/sysbios/family/arm/a15/smp/Cache.h> in this source code
    - add pdk_am57xx_1_0_xx\packages\ti\drv\vps\src\osal\tirtos\bsp_osal.c to your CCS project, add "BSP_OSAL_SMP_MODE_ENABLE" to Defined Symbols to make sure it uses:
    #include <ti/sysbios/family/arm/a15/smp/Cache.h>

    I can build the CCS project successfully without re-building those libraries. Hope this help!

    Hi 

    Finally. I gave up rebuilding some modules because of lack of guide. And I added  these source files to my project and it really works. Thank you again.
