Soumya,

As you probably know, this is a hardware exception from the controller and the message is spawned by SYSBIOS exception controller.

This exception is generated when an attempt to fetch an instruction from memory fails (check chapter 7 of SPRUGH7 ).

As the error message suggests, you can check the ROV to try to obtain further details about its root cause. Also, the error shows the PC is located in external memory (pc=0x88cda294), therefore it is possible that something misconfigured the external EMIF peripheral during execution.

Since this issue is very tied to the hardware, we at the CCS forum will not be able to help you much further. I will then move this thread to the device forum so the experts there will be able to give a more precise assessment and possible causes, ok?

Best regards,

Rafael

Hello Rafael,

Thanks for your response.

Unfortunately I cant use ROV to debug this as the binary is built in command line linux env and the loaded onto EVM6670 as external program.

So i need to find ways to debug this problem without any GUI method. I will definitely wait for the HW team to response while I dig into more details of this exception dump.

Also I have enabled exception print and will be posting it soon.

Soumya,

Can you hook up an emulator open a dissassembly window to the location listed by the PC register in the dump and provide a screenshot of the window (grab at least 8 instructions before and 12 instructions after if you can.)

A few other questions:

How is DDR3 being configured?

How are you loading code?

Are you verifying that the code load was correct?

Usually something like this is going to be do to corrupt data at the location, in this case in the DDR3 memory, and often the mistake is that the DDR didn't get configured, or was configured incorrectly.

Best Regards,

Chad

Hi Chad,

Please find below the exception and the disassembly output.

To answer your questions: I am generating the binary using linux command line build with CCS library and loading it as external program in CCS GUI.

Once loaded properly, I get the play/run option in the debug window. Regarding DDR3 your doubt can be true that its not properly configured. Actually all most all sections of the executables I have kept in DDR. Please check below cfg file.

Also to add, this happened once I added (Timer->HWI->SWI->App code) support in my code.Looks to me it happened during timeout.

Soumya,

Thanks for the dump, but I'm going to have to ask you to do it again, and this time showing the Dissassembly around the value in the B3 register. In the C6x architecture B3 holds the return pointer of the call. Some call is jumping to 0x0, so that's where we should be looking (i.e. B3 holds the PC of where the failure occurred, the current PC is the Exception Handler.)

Best Regards,
Chad

The instruction at 0x8949B6EA is what's causing the problem. I'm not sure if it's not a valid generated code or that you had a corruption. I'd load it in the simulator and take a look at that address and see if it's the same opcode loaded.

If you take a look at the dump B5 is 0x0, this instruction is trying to branch to B5 or 0x0, note that it's BNOP B5, 0 so there's 0 states NOP's extra executed so the branch isn't going to be taken until it's sitting at 0x8949B6F0 (when it's doing the BNOP Addres, 5 (sitting in it's delay slots for the branch.) Also, note that before the BNOP B5, 0 there wasn't a moving of the PC value w/ offset (ADDKPC) to the B3 register, so nothing had saved a return pointer, and so the BNOP doesn't make since for that reason either. Also, the fact that it's actual branch time is going to be during the delay slots of another branch outside of the routine, would not be generated (i.e. it would branch to the location in B5 and 3 cycles later it would have branched to 0x8949B6C8 from the other branch instruction.)

Again, I'd check this in the simulator first to see what the instruction should actually be, but it would appear to me that you're having DDR corruption.

The GEL file with the EVM can be used to configure the DDR - load the GEL file and use the Init_EMIF_EVM hotmenu.

Chad
