Tool/software:

Hi,

Could you guide for below boot error?

Customer made the board based on C2000 LaunchPad XL TMS320F28379D V2.0.

Customer is programming and debugging with CCS and XDS200 and using Flash Boot Mode.

At debug, when it's not RUN, boot error occured.

At first time, CPU1 works but CPU2 not works.

At next time, both are in boot error.

When they tested the code at LaunchPad, CPU1 works but CPU2 not works.

Please guide next step.

When customer provide the f/w and schematic, could you review them?

Thanks.

Hello,

Could you please provide more detail on the issue? It is unclear what is happening here.

What is the customer trying to do? Are they connecting the device via CCS and attempting to load/run code?
Can you please describe what you mean by "boot error"? Is there some error in CCS showing? What is the symptom/nature of the issue? Is the CPU jumping to an ITRAP ISR?
I cannot debug code for the customer, but I can make some suggestions on how to debug after gathering a better understanding of the issue.

Best Regards,

Allison

Hi.... this is andrew kim

1.I am currently programming and debugging using CCS. I am programming CPU1 and CPU2. First of all, since we are programming the BuckBoost power, we are implementing PID control using 6 PWMs. CPU1 is using CLA1, and CPU2 communicates with the PC through CAN.

2. CCS does not check the boot error, but when the program is tested in debug state and reset on CCS, it fails to enter the main program. Of course, CPU1 cannot boot alone, and CPU2 also cannot boot due to the same problem. Now that the program is almost complete, it needs to be booted on its own to test while powering on, which is difficult.

3. Since it may be a simple mistake on my part to send you the source code, I will send you the CMD file first.

Hi Andrew,

Thanks for the response. I'm not sure I fully understand the nature of the issue here yet - Can you reset the device and load the symbols of the boot rom so you can step through and see what line the device is stuck at? I will ask a colleague to help review the linker command file.

Best Regards,

Allison

The picture below shows the situation when the code is reset in CSS.

0x3FF16A (no symbols are defined) in debug window	
You can see the message.   In this state, when you press Resume, main() cannot be started.

I don't know if I don't understand the bootrom or the bootrom is damaged.  

Operating the boot switch didn't make much of a difference.

When I press resume on PIC2, PIC3 runs in an infinite loop.

I think it will be easier to understand if you know what kind of bootrom source code it is.

I'm not sure.  I would like you to point out what I am doing wrong.

[PIC1]

[PIC2]

[PIC3]

Hello Andrew,

You can step through the boot code/assembly of the device if you would like. Here is how I've done so with an F28004x LaunchPad (same applies to F2837xD):

Launch the target configuration
Change the auto-launch settings (uncheck the box as we discussed)
1. You can also use the "remember settings" button to save these debug settings
Connect to the CPU target
Click on the 'Load' button and 'Load Symbols'
Browse for the bootrom .out file for your device in C2000Ware
1. This should be at a location like {C2000Ware}\libraries\boot_rom\f2837xd\revB\rom_sources\ccs_files\cpu01\Release\F2837x_cpu01_bootROM_REVB_Golden_020314.out
Once you load the symbols, this should bring you to something like this (I'm using F28004x for this example)
You can step through this code and also run to the line that calls (LCR) the bootrom system init and then "step into" that function
This brings you to the boot.c

Let me know if you are able to load the symbols of the bootrom in a similar manner.

Best Regards,

Allison
