EVMK2G: intcVectorTable undefined symbol in CCS10.2

Hi Benito,

K2G has a C66x DSP, but you added intvecs.asm from the C67x CSL folder: C:\ti_hpc\pdk_k2g_1_0_16\packages\ti\csl\arch\c67x\src\intvecs.asm. 

Try to use C:\ti\pdk_k2g_1_0_16\packages\ti\csl\arch\c66x\src\intvecs.asm instead.

Dear mr. jianzhongxu,

thank you for your support.

I linked C:\ti_hpc\pdk_k2g_1_0_16\packages\ti\csl\arch\c67x\src\intvecs.asm, because its vector table is more similar to the vector table of omapl137. 

However, I followed your suggestion but the compilation error still remains.

I suspect that CCS10.2 does not compile the file intvecs.asm. This could explain the reason for which the symbol _intcVectorTable is not defined despite I correctly added the file intvecs.asm in my project.

Should I change other settings in CCS10.2 in order to properly compile the vector table?

Thank you for your support.

I share 2 details that could be useful in order to solve the problem:

1) Within the file library  C:\ti_hpc\pdk_k2g_1_0_16\packages\ti\csl\lib\k2g\c66\release\ti.csl.intc.ae66 there is the symbol _CSL_intcVectorTable while in my intvecs.asm there is _intcVectorTable. However I tried to replace _intcVectorTable with _CSL_intcVectorTable in my application without solving the compilation errors

2) I am performing a porting from OMAP to EVMK2G. The old project was developed in CCS5.1 with output format legacy COFF while the new project is developed in CCS10.2 with output format eabi. I read this post:  https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/49843/undefined-symbol-referencing-errors and I realized that in COFF, C identifiers are transformed by the compiler by adding an underscore to the beginning.

In my case I modified the intvecs.asm by erasing the character "_" before the symbol name. The symbol intcVectorTable is resolved but new errors appear:

Please, note that I correctly generate the obj files.

Thank you for the support,

Hi Benito,

When you port your code from OMAP to K2G, all C code will be automatically compiled for the new device. However, assembly code is device specific and you can't simply compile C674x assembly code for C66x. All the undefined symbols you listed above are C674x specific and unavailable in C66x CSL library.

Did you use pdk_k2g_1_0_16\packages\ti\csl\arch\c66x\src\intvecs.asm? What was the compilation error?

Dear Mr. Jianzhoungxu,

thank you for your reply.

I used the pdk_k2g_1_0_16\packages\ti\csl\arch\c66x\src\intvecs.asm.

Here below, the compilation error:

The error arises because in my application there is a function for the initialization of OMAP:

void dspdrv_omapIntSetup(void)
{
  /* set ISTP to point to the vector table address */
     ISTP = (unsigned int)intcVectorTable;

    /* clear all interrupts, bits 4 thru 15 */
    ICR = 0xFFF0;

   /* enable the bits for non maskable interrupt and */
    IER = 0xF2;

   /* enable interrupts, set GIE bit */ 
   _enable_interrupts();
}

Should I replace the intcVectorTable with an other symbol defined within the vector table of c66x?

Thank you for your support.

Dear mr jianzhongxu,

thank you for your support.

Last days I came across this post: https://www.programmersought.com/article/98974642208 that explains how to configure interrupts on keystone architectures by means of CSL APIs. 

The post provides also an example of interrupt configuration.

I tried to follow this post in order to configure the interrupts on K2G. 

I'll let you know if it works as soon as possible.

Best regards,

Benito Carotenuto
