`monitor rtt` interface? #1439

Open werediver opened 2 years ago

werediver commented 2 years ago

RTT support is super-useful, but without support in GDB server it's not available for integration, e.g. in https://github.com/Marus/cortex-debug

As I understand, pyocd rtt command cannot be used when a debugging session is active, which limits the use cases further.

Am I missing something? Is there any ongoing work on this topic or, perhaps, some plans? 👀

For reference:

(Sorry for late reply; I was sick for a long time.)

You're right that it's not possible to use the RTT support with cortex-debug (which I use myself). Right now the RTT support is entirely contained within the pyocd rtt subcommand. Fortunately, there is ongoing work (and some pull requests) to improve RTT support, and integration with the gdb server and output in a form consumable by cortex-debug is on the roadmap.

@flit hopefully nothing serious

It would also be very cool to have the possibility to flash while rtt is open. I am able to do this with jlink. I normally keep rtt open and repeatedly make code changes and flash.

Same is possible with the Black Magic Probe (BMP).
