TMS320F28388D: can not show printf result for CPU2 in CCS Console

Hello Strong,

In the Debug window in the debug session, are you making sure that the CPU2 core is selected? When debugging a device with multiple cores, to see its memory, variables, registers, etc. (I believe which may include console outputs), you need to select the CPU2 core to make sure you're in that part of the debug session.

Omer,

Yes, CPU2 core is selected, there is no issue to show its memory, variables, registers, only have issue that there is no result by using printf function in CPU2.

Hello Strong,

This may be a limitation with the debugger, I will check with another expert and get back to you sometime tomorrow.

Best regards,

Hello Strong,

There should not be a limit based on the debugger, I verified this with a F2837xD LaunchPAD running both CPUs, the print statements from both showed up on the console just fine. To confirm, can you make sure your Debug window looks something like this?

Both CPUs should be running, and the print statements for each program should be different.

Hi Omer,

Yes, I confirm the F28388D debug window like above,  only CPU1 have printf result.

Hello Strong,

Are optimizations turned off? Sometimes optimizations can produce unusual behavior. Other than this, I don't see any issue that could be causing this.
