CCS/CC2650MODA: printf does not create output in console

Janelle Duenas

Part Number: CC2650MODA
Other Parts Discussed in Thread: CC2650

Tool/software: Code Composer Studio

Hello,

I am working with CC2650moda and code composer v7. I am trying to display values obtained from sensors connected to the cc2650 moda into the console but cannot get printf to work. I removed most of my code to see if I could simply display “Hello World” on the screen and it still does not work. These are some of the things I have tried so far

*Make sure CIO function is enabled

*Increase heap and stack size (I have use multiple values and still nothing works)

*use System_printf and puts functions as alternatives to printf

*make sure stdio.h is included

*Use compilers 5.2.6 and 16.9.3

I do not see a CIO console appear at any point. Can anybody please help me to get printf working? Or let me know if you know of any other methods to print to the console.

Thanks so much in advance!

Best Regards,

Janelle

Looks like you already covered your bases on some of the more common root causes. Have you seen the below article? There are more suggestions there:

http://processors.wiki.ti.com/index.php/Tips_for_using_printf

Note that system_printf works differently. You may want to check out the below thread:

https://e2e.ti.com/support/embedded/tirtos/f/355/t/436740

Thanks

Hello Ki,

Thanks for your response, I have read the Tips for using printf,

I followed this link to output the printf values into a txt file...
www.youtube.com/watch

... but it only displays "Cortex_M3_0: GEL Output: Memory Map Initialization Complete.
Cortex_M3_0: GEL Output: Board Reset Complete." which is what the console does output, but not printf outputs.

I tried using System_printf with System_flush from a task as recommended in the thread mentioned

I made sure the following was in the .cfg file

"var SysMin = xdc.useModule('xdc.runtime.SysMin');
SysMin.bufSize = 128;
System.SupportProxy = SysMin;"

but still nothing.

Every other function works in Code composer like adc, pwm, and tasks.

Would you recommend another direction to make printf work?

Thanks so much for the help!

Best Regards,
Janelle Duenas

I imported the PWM LED example into my workspace, added a printf statement, included stdio.h and increased the stack and healp to 0x300 each. That allowed printf to work for my example. It looks like you have modified the example quite a bit. Can you share your project with me. I would like to try it in my environment.

Hello Ki,

I just re-imported the PWM led example, added printf statement and included stdio.h, and increased the stack and heap to 0x300, but when I build and debug I still dont see anything printed to the console. The CIO console never appears.

I am using code composer 7.01 and tested compilers 5.2.6 and 16.9.3

Below is the pwm.c file everything else remains the same but still no CIO console

Below is my modified project, but behaves the same as the simple pwm led project with print fThanks so much for looking into this, it is strange the pwm led file works for you but not me. Please let me know if I should check any other settings, I am not sure in what direction to go to solve this

hello,

Below is the pwm.c file everything else remains the same but still no CIO console

(Please visit the site to view this file)

Are you saying that you do not get CIO for pwmled2.c also? I added your file to my project but it worked for me:

Can you try loading my *.out file and see if you get CIO output?

Thanks

Ki,

Thank you so much for your help. Your test showed me it was an issue with my Code Composer Set-Up and not the code itselft. I accidentally disable CIO console and was running under the impression that is was enabled. Additionally, I was running the code incorrectly. When I debugged it, I would stop it, which loads the code to the CC2650 and I expected the printf statements to appear. However I should have used the resume button to run the program instead. I apologize for my mistakes, but thank you so much for your help and time. Both printf and System_printf work now.
