Code Composer 5.3.0 - using MSP-EXP430FR5739 - simple printf not working

Chris McDaniel1

Other Parts Discussed in Thread: MSP-EXP430FR5739, MSP430WARE

I am trying to debug using simple printf. I have printf set to minimal. I increased the stack and heap size very substantially...... 4096 and 3072 respectively.

Stepping through the assembly created for printf seems to crash at a line with CALLA &_lock. I have tried with CIO enabled and disabled.

I also tried with putchar.....it does the same thing.

The way I understand Code Composer Studio debugging.....printf should go straight to the 'Console'.

Thanks for any help!!!!

Thanks for the link.

I had already been through all of those settings. I tried larger stack/heap values. I am using the MSP-EXP430FR5739 development board.

As i understand it, printf is suppose to be directed to the console by default. Is there a need to setup a com port or any other interface to make this work??

Thanks for any help!

Maybe you're looking into wrong console. There is a drop-down in CCS console window that selects different sources:

Hi,

Does the built in hello world example work? This is a good first step to verify things.

Best Regards,

I can confirm that the helloworld template does NOT work on FR5739 for me. I am going to try increasing stack/heap.

So out of the box the template is not working. If I adjust the heap to 300 then it works.

I filed SDSCM00047129 to track this.

John,

Within Code Composer's "TI Resource Explorer" which template is considered the Hello World template.

Under 'MSP430ware/Devices/MSP430FRxx" I don't see a Hello World.

Thanks

Chris,

Go to the project menu and select "New CCS Project". This will run the project wizard and you can create a project using a small selection of templates. This one does not come as part of MSP430ware. You can also get to the same wizard from the welcome page within Resource Explorer.

Regards,

John
