TM4C123GH6PZ: Trouble Setting Breakpoint with the action

Daniel Belaish

Part Number: TM4C123GH6PZ

Hello, i'm trying to debug my application and i'm encountering the following errors on startup

When the program loads and starts it fails to reach the main function with autorun, and from then, setting any breakpoint will result with error -1066 "Remain Halted"
and the SW will break on another code.

important info:

1. i am using the TI provided gel files, so the debugger memory map is set properly.
2. it is not a hardware issue because the hardware is working in another project.
3. i have tried to compare between the projects in terms of linker & compiler flags without success.
4. i am able to read the memory locations mentioned in the errors (e.g. 0x1A6A8, 0x1A6D8, etc..)
5. the target configuration file is using a JTAG chain and is identical to the target configuration used in the working project.
6. the launch configuration is also identical to the working project.

I am using CCS1220 with emulation package 9.10.0.00080, the error has occurred on CCS1250 too.

Thanks.

Hello,

Are you able to do a manual launch and connect to the target successfully? If so, please disable auto-run to main and then load the program. Was that successful? If so, then try stepping through to main. If something goes wrong along the way, then it is likely an issue with the application putting the target into an bad state which in turn is causing the debugger to lose debug access.

Thanks

Hello,

I was able to connect to the target, once i loaded the application the errors began to appear, i disabled autorun as requested but still the errors appeared.
the message was Trouble Setting Breakpoint with the Action "Terminate Program Execution" which seems reasonable considering the fact that only program termination action is requested from the debugger.
The CPU halted at the _c_int00 routine when the program was initially loaded, stepping through the code resulted in error: Trouble Setting Breakpoint with the Action "Continue or Finish Stepping"

the very same application is used through my colleagues computers.
however, it is worth mentioning that the application is being flashed to a different address than the boot address due to bootloader concerns.

i would like further assistance in resolving the issue.

Thanks.

It sounds like the device got in a bad state after program load. This is usually an issue with the application or target configuration.

Do they have the same error also?

How is this being done? Is CCS itself flashing it to the different address or are you doing it external to CCS?

My colleagues does not have the same error

CCS itself flashes according to the .cmd file and then the debugger starts from the entry point.

the same target configuration is being used and works for my colleagues.
