CCS: Undefined symbol in build for AM571x M4

Charles,

In general the example code is better understood by the experts of the device forum. I will move your post there and you should get a reply soon.

Regards,
Rafael

Thank You

Hello Garrett,

Yes I did try that as I found via a search that the vps example was also using it in "Bsp_platformTda3xxInit" function. So I tried a variety of different include files with no luck.

The next step I tried which works is as follows: (I copied the below include files and code from the CSL_xbarIrqConfigure function into my code)

#include <ti/csl/soc/am571x/src/csl_device_xbar.h>
#include <ti/csl/soc/am571x/src/cslr_control_intr_dma.h>
#include <ti/csl/soc/am571x/src/cslr_control_core.h>
#include <ti/csl/soc/am571x/src/cslr_soc_mpu_baseaddress.h>

CSL_control_intr_dmaRegs *ctrlCoreIntrDmaReg =
(CSL_control_intr_dmaRegs *) CSL_MPU_IRQ_DMARQ_CROSSBAR_REGISTERS_REGS;
CSL_control_coreRegs *ctrlCoreReg =
(CSL_control_coreRegs *) CSL_MPU_CTRL_MODULE_CORE_CORE_REGISTERS_REGS;
Uint32 regIdx = (CSL_XBAR_INST_IPU1_IRQ_50 - 1U) / 2U;
Uint32 regLsb = (((CSL_XBAR_INST_IPU1_IRQ_50 - 1U) % 2U) * 16U);
Uint32 regMsb = regLsb + 16U;

ctrlCoreReg->MMR_LOCK_2 = 0xF757FDC0U;
CSL_FINSR(ctrlCoreIntrDmaReg->IPU1_IRQ[regIdx],
regMsb, regLsb, CSL_XBAR_MAILBOX3_IRQ_USER1);
ctrlCoreReg->MMR_LOCK_2 = 0xFDF45530U;



The only thing I can figure is when I look at the CSL libraries for the c66 DSP but not the A15 or the M4 I find a second library:

c66 csl libs:
ti.csl.aa66
ti.csl.aa66e
ti.csl.intc.aa66 - Is this the library that has the interrupt functions?
ti.csl.intc.aa66e - Is this the library that has the interrupt functions?

m4 csl libs:
ti.csl.aem4

Do I need a ti.csl.intc.aem4 library for the m4 to be able to call "CSL_xbarIrqConfigure"?

Garrett,

   Thank you for the explanation of what the other library's are for and that only one library is needed for the M4 that helps.

I still do not understand why I cannot call "CSL_xbarIrqConfigure" from my code with the ti.csl.aem4 library added to my project.

Below is how I included the library into my project are there any other steps I am missing.

Charles,

Do you have the following code in your .cfg file?

/*use CSL package*/

var socType           = "am571x";

var Csl = xdc.loadPackage('ti.csl');

Csl.Settings.deviceType = socType;

Above will link ti.csl.aem4 into sysbios.aem4, check the build log:

Garrett,

  1) Thank you again I did not have those parameters in my .cfg file. So I added them.

var Defaults = xdc.useModule('xdc.runtime.Defaults');
var Diags = xdc.useModule('xdc.runtime.Diags');
var Error = xdc.useModule('xdc.runtime.Error');
var Log = xdc.useModule('xdc.runtime.Log');
var LoggerBuf = xdc.useModule('xdc.runtime.LoggerBuf');
var Main = xdc.useModule('xdc.runtime.Main');
var SysMin = xdc.useModule('xdc.runtime.SysMin');
var System = xdc.useModule('xdc.runtime.System');
var Text = xdc.useModule('xdc.runtime.Text');
var HeapMem = xdc.useModule('ti.sysbios.heaps.HeapMem');
var BIOS = xdc.useModule('ti.sysbios.BIOS');
var Hwi = xdc.useModule('ti.sysbios.family.arm.m3.Hwi');
var Clock = xdc.useModule('ti.sysbios.knl.Clock');
var HalHwi = xdc.useModule('ti.sysbios.hal.Hwi');
var Task = xdc.useModule('ti.sysbios.knl.Task');
var Timer = xdc.useModule('ti.sysbios.hal.Timer');
var Idle = xdc.useModule('ti.sysbios.knl.Idle');
var Semaphore = xdc.useModule('ti.sysbios.knl.Semaphore');

/*use CSL package*/
var socType = "am571x";
var Csl = xdc.loadPackage('ti.csl');
Csl.Settings.deviceType = socType;

  2) I added the  #include <ti/csl/soc.h> file only as you requested earlier.

3) I then built:

Is there anything else I could be missing. I really appreciate your attention to this matter.

Garrett,

One more question. I am using an early release of pdk_am57xx_1_0_3 and I see in your examples you are using pdk_am57xx_1_0_4.

Do I need to upgrade to the latest version?

Charles,

CSL_xbarIrqConfigure() is supported in pdk_am57xx_1_0_3, see pcie example project. We recommend you upgrade to pdk_am57xx_1_0_4 but the build issue should be not because of pdk version. Can you try to create the PDK pcie example for M4 and build to have a sanity check?

-Garrett

Garrett,

      Give me a day or two to see all what needs to get upgraded in our development environment. I also have to keep my self and two others all on the same page and be able to build and release software. 

      I will get back to you early next week most likely.

Thank you again for your help.

Hello Garrett,

OK I updated my development environment to the the latest CCS and SDK and I do not know if I told you this but I am developing in windows not linux.

I rebuilt my project and again get the same linker error for CSL_xbarIrqConfigure().

I then decided to try to rebuild the CSL as follows:
C:\ti\pdk_am57xx_1_0_5\packages>pdksetupenv.bat

C:\ti\pdk_am57xx_1_0_5\packages\ti\csl\gmake app_clean

I get the following error:

I find it very interesting that the error is on the file csl_device_xbar.c which is the file that contains the function CSL_xbarIrqConfigure().

I have to figure out how to build the pcie example for the m4 next.
