CCS/TMS320F2806: Check optimization level in one file during compiling

Daniel Studer87

Part Number: TMS320F2806

Tool/software: Code Composer Studio

Hi,

In my project I have to set the optimization level for one file off. I now this can be done for every file within its properties.

But sometimes to debug the code, I switch off optimization for all files and afterwards I set optimization on again. But if i forget to switch off optimization for the one specific file, my code is not running anymore.

Is there any way to check automatically the optimization level of a file during compiling to get a compiling error or warning?

Thanks for helping.

Regards,

Dani

I have not seen any way to do it from CCS settings.

Probably the easiest way is to call a sed scripts on a Console output file.
In my environment, sed is here: C:\ti\ccs820\ccsv8\utils\cygwin

Do you know why this happens?

Hi Tom,

No I have not had time yet to check what code does not run anymore in that file.
It's a file with code for EEPROM read and write per I2C and I2C interrupts are located in this file.

Worth to check sometime later however sooner would be better.
Globals used within ISRs have to be volatile.
Could you confirm that you use volatile keywords for globals?

I checked the code and every global variable used in I2C_int1a and I2C_int2a is volatile.

Hi,

I coudn't find the problem in my code, why it is not running anymore, if optimization is on.

Now I just set some of the function to disable the optimization with the following pragma:

#pragma FUNCTION_OPTIONS(ISR_I2C_Int2a, "--opt_level=off")

So I don't have to sitch off the optimization for just one file.

I have to find the problem later, why the code is not working with optimization.

Best regards,

Dani
