Serial Communication on Tricore on TC 297B

[User13554]

Hello All,

I am trying to establish serial communication on pc for debugging(TC 297B) and display the register contents on serial terminal window. I am using Hi Tech Tri core tool chain.
I am able to establish serial communication with single core but when I run the same program with all the 3 cores enabled, then the output of the serial window is always a junk.
Its not the issue with baud rate I checked it.Any inputs is appreciated.
Thanks in advance

You use one serial interface for all three cores?
You thought about the problem of the three cores using the interface in parallel?

[User13554]

Yes. All three cores are enabled but only core0, is sending and receiving.

[User11554]

Are you sure to program isn´t running on all cores in parallel - would explain your problem.

I figured out that there was grounding problem with the board. I couldnt fix the serial port problem. But any how I am using gpio pins for my testing.

Hello, I use the example code "HelloSerial_ApplicationKitTC275C-Step" and I'm not able to display the output text that the serial port send by usb. How can I make it on the free tool chain IDE. I try to retrieve something by the terminal of RealTerm in the port 38400 but I have nothing (I have just the connection between the PC and the board by USB/micro USB).

Thank you in advance.

Hello bsr656,

You can extend the code example project for the UART module to show the registers you are interested in: UART training code example.
this example also comes with a tutorial, which can be found here: UART tutorial.

Furthermore, if you are interested in other modules and you want to start programming for AURIX™, you can get the new Integrated Development Environment (IDE) here: AURIX™ Development Studio and get inspired by numerous trainings from here: AURIX™ Trainings.

If you are not familiar with Eclipse based IDE’s checkout the Getting Started guide!

Hope it helps,
