DSP part seems quite normal as well. There even was once a GCC port to Tricore, version 3.3 from HighTec (now part of Infineon itself), but not even the wayback machine has the files for that anymore: https://web.archive.org/web/20150205040416/http://www.hightec-rt.com:80/en/downloads/sources.html Given the age of that port it's probably better to start from scratch anyway :) (the current stuff from them/Infineon doesn't seem to be GCC-based anymore?) Ciao, Michael. ---1609957120-490216190-1687184208=:13548--
