TDA2SX: Error when loading EVE program in CCS

Hi JM,

   Can you make sure you have closed all the open memory, variable, expression windows before connecting to the ARP32 core?

Regards,

Anshu

Hi Anshu,

  I closed all the windows you mentioned and reloaded the program, but the error still occurs.

In addition, I tried to modify the TDA2xx_multicore_reset.gel file and add the following settings:

SetupEveMmuEntry(cpu_num, mmu_num, 15, 0xb5000000, 0xb5000000, EVE_MMU_PAGESIZE_16M);
SetupEveMmuEntry(cpu_num, mmu_num, 16, 0xb6000000, 0xb6000000, EVE_MMU_PAGESIZE_16M);
SetupEveMmuEntry(cpu_num, mmu_num, 17, 0xb7000000, 0xb7000000, EVE_MMU_PAGESIZE_16M);

    WR_MEM_32(EVE_MMU_CNTL, ((RD_MEM_32(EVE_MMU_CNTL)) & 0xFFFFFFFD) | 0x2);

    /********************/
    if(EVE_SW_CONFIG == 1)

    }
    if(VISION_SDK_CONFIG == 1)
    {
        GEL_TextOut("DEBUG: EVE%d MMU0 configured as per VisionSDK requirements!!!!\n",,,,,, cpu_num);
    }
}

Then the error message no longer occurs. But I’m not sure if it is right, the system isn't working.

Hi Anshu,

Try to add some setting into TDA2xx_multicore_reset.gel

SetupEveMmuEntry(cpu_num, mmu_num, 15, 0xb5000000, 0xb5000000, EVE_MMU_PAGESIZE_16M);

SetupEveMmuEntry(cpu_num, mmu_num, 16, 0xb6000000, 0xb6000000, EVE_MMU_PAGESIZE_16M);

SetupEveMmuEntry(cpu_num, mmu_num, 17, 0xb7000000, 0xb7000000, EVE_MMU_PAGESIZE_16M);

SetupEveMmuEntry(cpu_num, mmu_num, 18, 0xb8000000, 0xb8000000, EVE_MMU_PAGESIZE_16M);

and run Scripts->TDA2xx MULTICORE Initialization->TDA2xx_MULTICORE_EnableAllCores

It can solve the issue "Trouble Reading Memory Block at 0xb5000000 on Page 1 of Length 0x4: (Error -1065 @ 0xB5000000) Unable to access device memory."

But there are no any response after Load Program.

Could you give some suggestions?

Thanks

Daniel

Hi Daniel,

     Before loading the program can you do CPU reset on EVE core and then try?

Regards,

Anshu

Hi Anshu,

    We did CPU reset on EVE core and other cores before loading the program.

Regards,

JM

Hi JM,

      Can you also confirm whether you are able to run any other application which comes as part of EVE SW release as it is (i.e. without any changes from your side)?

Regards,

Anshu

Hi Anshu,

    I used TDA2x EVM to run the application you mentioned, and the system cannot work. What steps need to be followed?

Regards,

JM

Hi Anshu

Could you provide sop or any suggestions for this issue?

Thanks

Daniel

Hi Daniel,

    Can you confirm if you followed all the below steps : 

TDA2X :

1. Goto /ccs_base/emulation/TDA2X and set EVE_SW_CONFIG macro to 1 in TDA2xx_multicore_reset.gel file

2. In CCS, launch the Target Configuration for TDA2X.

3. Select the 'CortexA15_0' Target -> Do a 'System Reset' -> Select 'Connect Target'.

4. Select the 'CortexA15_0. Goto ‘Scripts’ menu -> ‘TDA2XX MULTICORE Initialization’ -> EVExSSClkEnable_API

5. Select 'ARP32_EVE_x' Target -> Do a 'Connect Target' -> Do a 'CPU Reset'.

6. Any binary can now be loaded to ARP32_EVE_x and executed.

7. To execute EVE starterware mailbox example – additional steps will be required for interrupt mapping – please refer starter ware documentation for the details 

Regards,

Anshu

Hi Anshu,

JM follow the steps but it is still not available.

He can not see any response after Load Program.

Is there any response that you follow the steps?

Thanks

Daniel
