6678 Ethernet emacExample emulation error

Did you ran the gel file for initialization of the peripheral. THis looks liek it is failing in QMSS not in emulation.

Thanks,

Arun.

Hi Arun,

I was not using any GEL files.  After your response, I found two GEL files, and tried them, but still got the Error.

These are the GEL files I tried:

C:\Program Files\Texas Instruments\mcsdk_2_00_05_17\tools\program_evm\gel\evmc6678l.gel
C:\ti\ccsv5\ccs_base\emulation\boards\evmc6678l\gel\evmc6678l.gel

Here is what happened:

I left click Run, Load, Load Program, select the out file, then click OK.
I right click in the Debug view and select    Open GEL Files View.
I right click in the GEL files view and select    Load GEL.
I select the GEL file and click Open.
I see multiple setup messages scroll by in the Console view.
I click resume.
I see the error in the Console view Error Initializing Free Descriptors, Error: -137

Once you have connected the core 0 load the gel file and you will see a tab on the top called GEL. It will be populated with some entries. You need to click global_default_setup and then load and run the example.

Thanks,

Arun.

My CCS tabs look different.

I found it under      Scripts, EVMC6678L Init Functions, Global_Default_Setup.

I still get the same error.

Hi Arun,

I found something to make the error go away.
I used a C6670 instead of C6678 version of qmss_device.c.
(I also ran the GEL file)

Now the console says:
 [C66xx_0] ******* Ethernet Single Core Example Start *******
 [C66xx_0] **************************************************
 [C66xx_0] QMSS successfully initialized

The 6670 version of qmss_device.c has additional lines:

    /** Base queue number and Maximum supported AIF queues */
    {QMSS_AIF_QUEUE_BASE, QMSS_MAX_AIF_QUEUE},
    /** Base queue number and Maximum supported FFTC A queues */
    {QMSS_FFTC_A_QUEUE_BASE, QMSS_MAX_FFTC_A_QUEUE},
    /** Base queue number and Maximum supported FFTC B queues */
    {QMSS_FFTC_B_QUEUE_BASE, QMSS_MAX_FFTC_B_QUEUE},
    /** Base queue number and Maximum supported FFTC C queues */
    {QMSS_FFTC_C_QUEUE_BASE, QMSS_MAX_FFTC_C_QUEUE},
    /** Base queue number and Maximum supported BCP queues */
    {QMSS_BCP_QUEUE_BASE, QMSS_MAX_BCP_QUEUE},

That is strange. The lines you mentioned are not there in the shannon doesn't have those accelerators. Can you try again with the original qmss_device.c?

Thanks,

Arun

Hi Arun,

I switched it back and I get error -137 again.

Maybe I should be using .h files that come with the .c files, not those supplied with emacExample.

There is a qmss_types.h stored in emacExample and a different one stored in qmss (where qmss_device.c is).
There is a cppi_types.h stored in emacExmple and a different one stored in cppi (where cppi_device.c is). 

I will try some experiments.

Hi Arun,

I think I found a problem.

In properties-build-XDCtools-Package Repositories, I saw "${TI_PDK_C6670_INSTALL_DIR}/packages" followed by "${TI_PDK_C6678_INSTALL_DIR}/packages".  I deleted the 6670 entry and now QMSS and CPPI initialize.

[C66xx_0] **************************************************
[C66xx_0] ******* Ethernet Single Core Example Start *******
[C66xx_0] **************************************************
[C66xx_0] QMSS successfully initialized
[C66xx_0] CPPI successfully initialized
[C66xx_0] Error opening a PA Command Response queue
[C66xx_0] PASS init failed

Does that make sense?

Hi Greg,

Now it makes sense. thanks for updating. please let us know if you have any new issues.

Thanks,

Arun.
