Can't use logging in my Project

C.Lorei

Hello, I try to add Logging to the "UART Echo" from the tirtos resources. I have done all the changes, followed by the given description in the TI-RTOS 1.21 User’s Guide.

When I try to compile the code, there is an error because the function Log_info2() is unknown. So I include the xdc/runtime/log.h. Now I can compile the project without errors or warning.

But when I upload the project and run it on the controller - I get the message "Can't create HWI". This error message came from the USBCDCD_LoggerIdle.c line 382.

What's wrong or missing in my Project?

This is my UART echo Code.

What version of CCS are you using? What board are you using?

The examples try to minimize footprint. One way is to not have any dynamic memory allocation. Assuming you did not modify uartEcho.cfg, you can add a heap into the example by adding the following:

BIOS.heapSize = 4096;

The error you are getting is because you are trying to create a Hwi which requires memory. You can either add a heap into your example or start with the empty project instead.

Note: you can look at HeapMem in ROV to see how much memory is being allocated.
