Error: Elf file does not have _SEGGER_RTT symbol

I built some blinky examples with HighTec Rust Aurix compiler version 1.0.0 for the TC375 lite kit board. I am trying to run these elfs on my board via tricore-probe but I face this error:

I assume this means I need to utilize the rtt-target crate somehow. Do you have some examples for that (preferably with the Lite Kit board)?

Hey @gemesa,

Assuming I understand your problem correctly. To be able to use the tricore-probe you need to link against https://crates.io/crates/defmt-rtt. If you are working bare-metal you can check how Bluewind did it here (https://github.com/bluewind-embedded-systems/bw-r-drivers-tc37x/blob/main/src/log.rs).

If you want to use the PXROS (e.g., https://github.com/veecle/veecle-pxros/tree/main/examples/example-hello-world) you can check out how we did it here: https://github.com/veecle/veecle-pxros/blob/main/src/pxros/defmt_rtt.rs

This is exactly what I needed, thanks.
