Device blocked debug access because it is currently executing non-debuggable code

Hi Rasit,

This error has to do with realtime access to the processor.   The processor can block realtime - if you select "rude retry" then it will let the accesses from Code Composer take place. 

For more information on realtime through CCS please see:

http://processors.wiki.ti.com/index.php/Real-Time_Mode_Debug_with_CCStudio

Also, I would like you to include "F2802x_GlobalVariableDefs.c" file to your project, that can be found here:

C:\ti\controlSUITE\development_kits\C2000_LaunchPad\f2802x_headers\source

Refer the docs available here:

C:\ti\controlSUITE\device_support\f2802x\v210\doc

Hello Rasit,

Is there any SCI setting (GPIO28 and GPIO29) on your project (maybe by default they set as SCI)?

I also faced that error message when there was contention between GPIO28 and GPIO29 as SCI and with UART that used by the debugger/PC (actually this is contention from the board).

What board that you use for F28027? Also is it onboard XDS100 that you use for debugging?

If you use Launchpad-F28027, there is switch S4 to resolve this problem:

If your problem is considered from something else, please give us more detail that maybe we can help.

Best regards,

Maria

Dear Maria ,

I am using card designed by me. I also check GPIO28-GPIO29 pins they are set as SCI RX-TX pins in software but I am not using SCI comm. and in the card hardware these pins are not connected somewhere. 

By the way I am triying to solve problem. Very interesting things happens. I import  the project in the adress

device support/ f2802x / V210 / f2802x_examples / adc_soc

I compile, load and run the adc_soc program  using the same hardware. Error message  "Device blocked debug access because it is currently executing non-debuggable code" is not seen.  I checked ADC register everything seems OK. Real time mode works as expected. ADC register refresh occurs in watch window.

Then I try to reference this project to solve problem. Before this I again compile, load and run my project then I didint  see any problem. Error message is not seen. I didint make any changes in the software and hardware. Just I import and load -run adc_soc project then I switched to my project. 

I decided that If I can run the project I can work on with the same set up. But in that case after turning off and on again micro supply and again load -run the my project with same set up problem occured again.

OK, thanks for explaining your case more detail.

Btw, did you call CPU_enableDebugInt() (for clearing DBGM bit in ST1) in your code?

If not, please call this function CPU_enableDebugInt().

You can find the explanation in  this thread:

Also one more thing, in "Debug Configurations" menu (Run --> Debug Configurations --> Target --> Auto Run and Launch Options), please make sure that "Enable realtime mode" is unchecked.

Hi Maria,

I am using CCSV5. In debug options menu only " Enable polite mode" available and its checked. There is no option (as I see) Enable real time mode icon. I tried to paste "CPU_enableDebugInt()" function to my code. Some errors and warnings is appeared in console. I tried but I couldnt add this function.

On the other hand I still work on with adc_soc project example. In this project I see that watchdog is disabled before device calibration on line 76 with function  WDOG_disable(myWDog); 

if this function is commented the same error that is  Device blocked debug access because it is currently executing non-debuggable code is appeared. So problem can be related with disabling Watchdog before device calibrating.

I also paste this function WDOG_disable(myWDog); to my code some errors like cpu.h and wdt.h cant open. I triying to fix problems so that I can see what will happen while disabling watchdog before device calibration.

OK, let us know the result.

The picture that I showed you before was from CCSv5.4.

What version of CCSv5 are you using? Because in CCSv5.5, this option is also available.

Btw, for replacing CPU_enableDebugInt(), you can use:

    asm(" clrc DBGM");

Best regards,

Maria
