F29H850TU: Empty Multi-core Example failure

Hi Jozef,

Jozef Sedivy said:

empty_project_multi_c29x1.c in FLASH configuration with usage CPU1 and CPU3 only. The CPU1 gets stucked  at line

Can you please help describe the steps that you took to load the example after it was built? 

Jozef Sedivy said:

When I try to connect debugger to CPU3 shortly after its release from reset I am repeatedly getting message:

C29xx_CPU3: Warning: Target CPU may be stuck in a persistent fault state

If you check the Error Aggregator Registers, are there any errors being reported?

What version of the F29x SDK are you using and what hardware platform do you have?

Jozef Sedivy said:

After running the code for a while program crashes and I am unable to even pause CPU1 code execution. 

Do you see this behavior every time(ie. have tried this example multiple times and always the same result)?

Jozef Sedivy said:

What could be wrong? Could you please advise how to resolve this issue?

I'll need to know the details above to advise on what could be happening as we do check our examples before a software release to ensure proper functionality. 

Best Regards,

Marlyn

Can you please help describe the steps that you took to load the example after it was built? 

• Target configuration ->  debuger config -> Start Project-less Debug
• Under Debug view: Threads -> C29xx_CPU1-> Connect Target (CPU1 shows HALTED state)
• Run->Load->Load program-> multi_c29x1.out
• F5 to run the code to ESTOP instruction
• Under Debug view: Threads -> C29xx_CPU3-> Connect Target
• Run->Load->Load symbols -> multi_c29x3.out
• Run CPU1, Run CPU3
• CPU3 falls in reset state and synchronization with CPU1 never happen
  
   

 If you check the Error Aggregator Registers, are there any errors being reported?

C29xx_CPU1: Error Aggregator Status :

C29xx_CPU1: Error Aggregator Status Done

C29xx_CPU1: ESM_CPU1 Status :

C29xx_CPU1:   - ESM_EVENT_CPU3WD

C29xx_CPU1:   - ESM_EVENT_EPWMXBAR1

C29xx_CPU1:   Active/Pending and Enabled Error Events :

C29xx_CPU1: ESM_CPU3 Status :

C29xx_CPU1:   All Active/Pending Error Events :

C29xx_CPU1:   Active/Pending and Enabled Error Events :

C29xx_CPU1: ESM_CPU3 Status Done

What version of the F29x SDK are you using and what hardware platform do you have?

 I use SDK 26.01.00 with F29H85X-SOM_EVM. However, I have copied SKD files directly into the project, set include paths and removed SDK dependency. My project does not use CPU2 so I have removed code for CPU2, booting and sync from the main function.

Do you see this behavior every time(ie. have tried this example multiple times and always the same result)?

Every time
 

I'll need to know the details above to advise on what could be happening as we do check our examples before a software release to ensure proper functionality

Do you think it could be some device-provisioning/singning question?

Hi Jozef,

Please allow me some time to look over your issue as I will be out of office until tomorrow. 

Kind regards,

Hi Jozef,

Can you confirm that each core's project has its own .syscfg and generated board.c files? That is, there is both a .syscfg and board.c file in the empty_project_multi_c29x3 folder? If there is, can you share what the path for these files is? 

Kind regards,
AJ Favela 

HI Jozef, 

I am glad your issue was resolved, I will be closing this thread now. 

Kind regards,
