TMS320C6678: Linalg - level 3 BLAS example hanging

Here some additional info/insights:

Whenever I reset the EVM (full reset), the executable built via makefile works. The second time I run it, it crashes (didn't save the log, can post it if needed).

When I build via CCS, the build log is the following:

Note that if I'm not resetting the EVM before loading the program it will just hang at tiCblasNew().

If I reset the EVM and then load the program on it, I get the following:

Could you explain what is the difference between your CCS build and the makefile based build. Are simply building the example as is or have you made any modifications ? I don`t see any major issue in your build. Minor issue seems to be that you are using CGT compiler from CCS rather than the version packaged in the SDK but there shouldn`t be any impact due to that. I suspect that the CCS project is no longer being maintained in the library so the makefile may be the right approach to build the example. I am confirming this with the maintainer.

Also, can you clarify when you indicated the application runs when you perform full reset . what is you process of reloading the code. Are doing CPU reset on all cores or are you triggering warm reset before reloading ? Since failure log indicates that the application ran out of Heap Memory , have you looked at the ROV or tried to increase the HeapMem

Hi Rohan,

Thank you very much for your answer.

Regarding the differences between the two builds:

- I am not modifying any C-file. In CCS, I create an empty RTSC project and I then copy-paste dgemm_test.c, fc_config_c6678.c, ticblas_config.c and omp_config.cfg into the project folder. After adding the necessary products/includes, I have to manually enter the libarch and linalg static libraries for linking (it somehow doesn't link them automatically). The log I pasted in my past post was created from this.

- I tried to compare the linker.cmd files. Both files are the same, the linked libraries are the same, the only thing which is different is that it links the generated sysbios.ae66 and omp_config_pe66.oe66 libraries.

- I tried to rebuild the makefile example from scratch. For that purpose, I deleted everything except the makefiles, the .c files and the omp config. A thing which jumped to my eye is that it then complains

<Linking>
"/tmp/TI3dzRcEqs7", line 29: error: cannot find file "../common/linker_fc.cmd"

Shouldn't these .cmd files be generated automatically? If not, that could be a difference to my CCS build. Anyway, I added the linker_fc.cmd again and now I actually see something happening. After loading the program, I now get an error for the makefile project:

[C66xx_0] L2 SRAM size is 393216, total L2 size is 524288.
BLAS memory requirements - vfast size: 28160, fast size: 772224, medium size: 4700736, slow size: 4804.
Provided memory is not enough for BLAS!

I guess that before I wasn't rebuilding the sysbios.ae66 and the omp_config_pe66.oe66. However, I never changed anything to the cfg files. Isn't that example supposed to run on my EVM without changing anything? I will add here that it doesn't matter whether I use the compiler delivered with CCS or the one from the SDK - I tried both, same errors. At least the error above gave me some additional info, so I will first try to get this example going. I was able to identify which of the memory conditions required for that program are failing:

Provided memory is not enough for BLAS!
smem_size_fast=772224 > l2_buf_size=262144
smem_size_med=4700736 > msmc_buf_size=2621440

Still, it is a bit puzzling that the example wouldn't work without changing anything.

Regarding your other comments:

- When I meant full reset I meant that I would be disconnecting in CCS and then press the full reset button on the board next to the ethernet thing. I then reconnect via my target config file and I go on Run->Load Program or I press the bug button for debugging and it automatically connects and loads the program (tried both).

- Yes I will try to use ROV and also try to increase the heapMem since it now seems to be connected to the makefile example as well. About the linker_fc.cmd - shouldn't that be generated automatically? I can't see anything like that in my CCS build. I'll experiment with that as well. I'll post the results asap.

Thanks again and best wishes,

Idris

EDIT:

The following values are hard-coded in the example and don't seem to be configurable:

#define BLAS_L2_BUF_SIZE   (256*1024UL)     /* 256KB SRAM is available in L2 for C6678 EVM */
#define BLAS_MSMC_BUF_SIZE (5*512*1024UL)   /* reserve 2.5MB for BLAS */  

Which would mean that tiCblasGetSizes is simply giving me too big values back. What could I have done wrong then?

EDIT #2:

When I run the old example which - I guess - was built with the prebuilt libarch and linalg libraries, I get this:

BLAS memory requirements - vfast size: 28672, fast size: 245312, medium size: 2154688, slow size: 4804.

So fast and medium size are less than half of the other stuff in my example. I just rebuilt the llnalg library using the command

make DSPlibs MEM_MODEL=Small TARGET=SOC_C6678 LIBOS=LIB_RTOS

That is really weird, any hints on that?

EDIT #3:

Ok, I now know the following:

- If I include the linker_fc.cmd (attached) in my CCS project and I use they linlalg and libarch libraries delivered by TI, everything works fine (I luckily thought of saving them somewhere before rebuilding). This holds for both the makefile project and the CCS project.

- If I don't include the linker_fc.cmd, I will get errors like "Core 0 DMA not initialized" and "[C66xx_1] Failed to alloc edma handle CoreID 1" - why that?

- Remains to know what is the difference between the library you deliver and the one I rebuilt? My employer just told me that he would like to be able to build everything from source, and I feel like I'm doing everything as described in the README.

Your help is greatly appreciated.

Hi Rahul,

yes I face the same issues. Using the ti-processor-sdk-rtos-c667x-evm-05.01.00.11-Linux-x86-Install and also using the one referred to in the post. When I use the rebuilt library, the program fails in the following if-statement (from the example):

int config_mem_for_ticblas(double *l2_buf,   size_t l2_buf_size, 
                           double *msmc_buf, size_t msmc_buf_size, 
                           double *ddr_buf,  size_t ddr_buf_size)
{
    size_t smem_size_vfast, smem_size_fast, smem_size_med, smem_size_slow;
    void *l1d_SRAM_ptr;
    int l1d_cfg_err;
    
    /* First, verify the provided/available memory meet requirements */
    tiCblasGetSizes(&smem_size_vfast, &smem_size_fast, &smem_size_med, &smem_size_slow);

    printf("BLAS memory requirements - vfast size: %d, fast size: %d, medium size: %d, slow size: %d.\n", smem_size_vfast, smem_size_fast, smem_size_med, smem_size_slow);
    
    if(  (smem_size_vfast> lib_get_L1D_total_size()) /* total available L1D  */
       ||(smem_size_fast > l2_buf_size)       /* provided L2 size   */
       ||(smem_size_med  > msmc_buf_size)     /* provided MSMC memory */                 
       ||(smem_size_slow > ddr_buf_size) 
      ) {                                                            
        printf("Provided memory is not enough for BLAS!\n");
        exit(0);
    }
...
}

The rebuilt library seems to have higher memory requirements.

Hi

Any update on recompiling the library? Were you able to reproduce the problem or are we doing something wrong compiling the library?

Thanks and best wishes,

Idris
