The current state of tricore target is in some areas more of a rudimentary implementation and lacks many features, especially disassembly.
Your error has something to do with the "in_asm" logging.

In our case we test tricore implementations using a dummy device which prints to the commandline.
The bare-metal elf then writes logging strings one char at a time into the dummy devices address.

If you like, I can send you patches for a "real" hello_world example including dummy device.

Best regards,

Andreas
