Compiler/TMS320F280049C: Break at address "0x3fbd92" with no debug information available, or outside of program code.

Could you please check this thread

Thanks,

Katta

Hi,

Even when I remove all the library files and attach new ones, I find the same message being displayed on the screen. Since I don't find this during RAM link, I'm guessing that it does not have to do with an address with no actual code? So that leaves me with no debug symbols. How will I be able to run it making sure that the symbols are properly aligned for the program?

This happens when I run the program  with flash. Is there an example routine I need to follow when I use flash memory? Most of the examples I found are run on RAM. 

Regards

I have the same problem after change included file 280049C_RAM_lnk.cmd to 280049C_FLASH_lnk.cmd.

Hi Reshma,

You can refer C:\ti\c2000\C2000Ware_<Version>\device_support\f28004x\examples\led example with build configuration "CPU1_FLASH"

Please let me know if you find a similar issue with this example. Hope you are using the same CCS workspace to build and run the example.

Thanks,

Katta

Hi Anton,

As I mentioned above please use the example C:\ti\c2000\C2000Ware_<Version>\device_support\f28004x\examples\led example with build configuration "CPU1_FLASH"

You have to use "_FLASH" and "_LAUNCHXL_F280049C" predefined symbol along with using 280049C_FLASH_lnk.cmd file.

Thanks,

Katta

Hi, Katta!

Thank you for your reply!

Yes, predefined "_FLASH" has solve problem with "Break at address "0x3fbd92"....". But application doesn't run after power turned off and then turned. It works only in debug session until power is turned off. That is equal behavior for my app and for led_example.

Hi Anton,

Have you configured the launchpad switch settings as "Boot from Flash"?

Please refer "Device Boot Modes" section in "ROM Code and Peripheral Booting" http://www.ti.com/product/TMS320F280049 TRM

Thanks,

Katta

Excuse me, i fogot to say that i work with 280049C on my own PCB, not launchpad. I tried to select boot mode from flash (vary BOOTPIN_CONFIG = 0x5AFFFFFF/0x5A000000 and BOOTDEF_LOW = 0x03, BOOTDEF_HIGH=0x00), it didn't help.
But a few minutes ago i tried run led_example on my controlCard with Piccolo 280049M and thats work without debugger. I'm confused and don't know what else can i do.

Hi Anton,

On the Piccolo 280049M controlCard the switch settings are configured as "Boot from Flash". So it worked.

Can you check your PCB schematic on how to configure the switch settings as "boot from flash". Did you configure GPIO24 and GPIO32 as '1'?

Refer Piccolo 280049M controlCard schematic for reference.

As the query now is about configuring boot settings, could you please raise a new thread? The boot loader expert will guide you.

Thanks,

Katta

Hi Katta,

I did as you suggested, but that program is not getting executed, both with RAM and FLASH. THough it gets built, now the program is not getting debugged.

I've inserted the picture of what I observed. 

Hi Reshma,

Please let me know the boot settings you used? What change did you make to the existing switch setting?

What was the original setting? In the original setting, you didn't have this issue i guess.

As per the section 2.1.6 Boot Modes in F280049X launchpad user's guide 

what modification did you do?

Thanks,

Katta

Hi,

The only change I made is changing the active CPU1-RAM mode to active CPU1-FLASH mode in the properties. The configuration was changed from CPU1-RAM to CPU2-FLASH. Though it was applied, the main code did not show that it was CPU1-FLASH activated. Now none of the example programs are getting debugged, and it shows the same issue.

Hi,

Could you please check if you are using TMS320F280049C_LaunchPad.ccxml target configuration to launch?

By default for most of the examples, we give TMS320F280049C.ccxml as the default target configuration file which can be used for control card but not launchpad.

Thanks,

Katta

Hi,

I've used TMS320F280049C launchpad to execute the program. Is it because it's launchpad it's not getting debugged? This is the target configuration in which the program is working.

Hi Reshma,

You can see the video at https://www.youtube.com/watch?v=km9bbzIgku0 to check how to configure the target configuration file.

You can debug on the launch pad.

When you mention "program is working" -> is it working in RAM but not in Flash?

I could see a "TMS3200049C_XDS110_2PIN_JTAG.ccxml" in your project. Are you using it as the default configuration file?

You can replace the existing target configuration file in "targetConfigs" folder with this one.

Thanks,

Katta

Hi,

Thanks, that helped. Should I be doing the same changes to my own program as well? If I do, will the original files be affected?

Regards

Hi,

According to the video that you had sent, the adc program was worked fine when it was configured with the linker command file. But when I used generic flash, it doesn't work and I'm back to square one. The same occurs when I use FLASH in the linker command.

1. When I did "right click on the project -> Build Configurations -> Set Active -> Choose "CPU1_FLASH" to change the build configuration."

2. When 28004x_generic_flash_lnk.cmd was included instead of 280046C_RAM_lnk.cmd

3. When I used 280049C_FLASH_lnk.cmd instead of 280046C_RAM_lnk.cmd

The errors disapear when I go back to 280046C_RAM_lnk.cmd and debug it.

Is there anyway I could solve this?

Regards

*280049C_RAM_lnk.cmd

Typing error

Hi Reshma,

For moving from RAM to Flash configuration, changing linker command file is not sufficient.

Please add predefined symbol "_FLASH" in the project properties -> Build -> C2000 Compiler -> Predefined Symbols. 

As you are using launchpad add "_LAUNCHXL_F280049C" too.

These settings exist in led_ex1_blinky (CPU1_FLASH). So, please refer to it. 

Let me know if you still face the issue. 

Thanks, Katta

Hi,

The example project seems to be working fine in FLASH mode. But the program that I have written is not debugging even after including the symbols on referring to led_ex1_blinky (CPU1_FLASH). The configuration does not change from debug/release to active RAM/FLASH. Is there something else I'm missing?

Regards

Hi,

Thanks. It worked finally!
