different behavior of Report function when we use message queues.

amanaganti vinod kumar1

Hi,

I am using ti-rtos and code composer studio. I created msg-Qs each of size 10bytes. When I use these mailbox communication Report function is printing empty lines on console, I have observed following cases

1) Without msg-Qs Report is fine

2) After msg-Qs creation, if we don't use Report is working fine

2) But when start using msg-Qs if we call Report its just able to print Newlines but no data.

Do we have to take care of anything while using msg-Qs and Report??

Application size is 230KB, is there any relation between Report and msg-Qs in memory wise.

Thanks for your help in advance.

If using TI-RTOS, tying using the following instead. This will printout to the console within CCS.

System_printf("This will output to console\n");
System_flush();

Hi Glenn,

I am working on customized board where there is no debugger to use. I observed one thing when I reduce the number of queues Report is started working.

How many queues can be used at a time and why is this behavior happening? if anything need to change in stack or heap sizes please let me know.

Hi Vinod,

From the above mentioned observations it looks like there is some memory corruption issue in the system.
There is no restriction on the number of queues as long as the memory permits.
Can you try to increase the stack and heap sizes?

You can increase them in the CCS GUI in the build options.
Show Build Settings => ARM Linker => Basic Options => Heap Size/ C system stack size.
