Clear Console Screen output with QEMU and GDB [message #1837876]

I am using the QEMU debugger to emulate a Cortex-M4 MCU (STM32). So far the project works as expected and I can output information via gdb and the semihosting interface.

However, I was wondering if I can clear the console output with a semihosting command or if there is a method to clear the console from my C project. My final intention is to print out the values of some variables I am interested in an specific interval as I do not want to pause the program.

At the moment I am able to print the information but the console writes a new line for each statement (as expected). But I would like to clear the screen and print the new information so I always get a nice display of the latest values in the console. I also tried to check if there a live watch feautre for QEMU/CDT but did not find it.

Any information pointing to visualizing values at real time or clearing the console to achieve this is appreciated.

If the output terminal supports ANSI you can send '\033[2J' to clear the entire screen.

The Eclipse console can be made ANSI aware with "ANSI Escape in Console" plugin.
The "TM Terminal" emulates a VT100 which supports ANSI.

Both are available from the Market Place.
Search for "ANSI".

Not sure what is being used for the terminal if you are using remote debugging.

UPDATE:
Since QEMU with Eclipse is a third party plugin,
you might get more help at the developer's site.
This forum is really for vanilla CDT.
