CCS/LAUNCHXL-CC1310: No debug console output with CCS, but loadti.sh works fine

Part Number: LAUNCHXL-CC1310

Tool/software: Code Composer Studio

For some reason CCS no longer shows debug console from my application.

I'm using System_printf with SysMin as usual, and loadti.sh works fine, giving expected debug information from my code.

If I pause CCS and check the SysMin module, it says the buffer is drained, since System_flush is being called regularly and appears to succeed.

If I check the buffer manually, it contains the expected text. The pointers indicate a successfully drained buffer.

I can't find any settings related to whether CCS chooses to pick up debug information from SysMin's System_flush, or any details on how specifically they communicate with each other.

Since everything works perfectly with loadti.sh, I suspect that the issue is within CCS somewhere.

Any ideas on what to check, or why this might be happening?

    In the project properties under Debug -> Program/Memory Load Options for the Cortex-M3 is the "Enable CIO function use (requires setting a breakpoint)" option ticked?

    If the "Enable CIO function use (requires setting a breakpoint)" option is not ticked that will cause the CCS debugger to ignore any System_flush (CIO) request from the target.
