Are there plans to support Infineon's Tricore architecture? The MCU's ASIL rating goes up to ASIL-D and Infineon is a very popular choice for automotive MCUs, so it seems like a great fit considering Zephyr is targeting ASIL-D. |

@ilanbiala no plans currently however, we would consider any contributions supporting this architecture. |

@ilanbiala I have a received xmc4000 based development board today. I will start working on this for Zephyr support. I will be able to start for Tricore after this. |

@parthitce just wanted to see if you ever got a chance to work on Tricore support? |

@ilanbiala Yes I did ported the arch parts of the Zephyr with the help of Aurix 2x ISA. But the board which I have from Infineon is based on Aurix 3x and it's not straight forward with the ISA for 3x series. I had to go via various NDA process which is almost done and waiting for Infineon to release the ISA in their collaborative platform. IFX HAL is BSD licensed in general, but am still not sure about the open sourcing the IFX based in 3x. But HAL for 2x is possible. So the SoC porting is yet to be done and waiting for the ISA and license clearance from Infineon. I used the Toolchain from hightech (close sourced), but there is also an attempt to port the GCC backend for tricore from my end. GCC backend work is posted here: https://github.com/parthitce/gcc, but it's long way to go. I will push the WIP tree for tricore Zephyr port once I get the license clearance from Infineon. |

Hey, whats the status on the tricore port? I have quite some experience with the tc3xx devices and a few boards to hand. I just saw one commit in the branche there. |

Hey, I startet the work to add Support for tricore Architecture. I'm able to Boot my tc37 and context switching is mostly done. Irq and gpio are next. Then I'll publish what I have, but the rest is up for debate. |

Hi @go2sh that sounds promising. I have a TC37AED board here I'd be interested in using with Zephyr (https://www.infineon.com/cms/en/product/promopages/AURIX-microcontroller-boards/application-boards/secure-ethernet-gateway/). |

That would be great. For our project we’re using gcc 11. Currently I run it via wine after extracting it from ADS, but I’ve just built tricore-gcc 11 for Linux and will switch to that if there are no issues. |

Quick update, Infineon did share the Linux version of the DAS service, I haven't been able to get it to work sadly. It uses some out of band ftdi library instead of the linux ttyUSB system, so you have to do a little dance to prevent linux from grabbing the device in order for the ftdi library to find it. |

Can you check if the Board file mentioned is there? Maybe there is some spelling error. Deleting the cmake cache and zephyr cache might help as well. |

Hey @cperkulator , sorry for the late response, I was in a hurry at my work. I faced the same problem as you, doing a clean rebuild resolved this issue. I don't see what is behind of such problem. |

I'm experiencing the same issue as @cperkulator. I'm trying to reproduce the issue under GDB like this: This is the backtrace I get when linkink zephyr kernel: This is the portion of code that fails: static void
lang_memory_set_current(lang_memory_region_type *r, bfd_vma dot)
{
lang_memory_region_mirror_list *l;
lang_memory_region_mirror *gr;
bfd_vma offset;
r->current = dot;
offset = dot - r->origin;
for (l = r->mirror; l; l = l->next)
{
for (gr = l->mirror; gr; gr = gr->next)
{
/* do not set backward
if one region is in multiple groups the DOT may have been
increased due to an allocation in one of the other regions
*/
if (gr->region->current < (offset + gr->region->origin) )
gr->region->current = offset + gr->region->origin;
}
}
}This is a piece of code added in EEESlab/tricore-binutils-gdb@78991a3 to support linking for Tricore architecture. After a quick and not-so detailed look, it seems that the linker espects the ROM memory region to have a mirror, which is actually not initialized, and the dereference of an invalid pointer causes the Segmentation fault. Maybe the problem is in the tricore LD linker script provided by @go2sh , but I'm not an expert and could be wrong For me, doing a clean build does not solve the issue. PS. If it's useful to someone, I added Github Actions to build and release tricore-elf-gcc executables for both windows and linux in my fork: https://github.com/NoMore201/tricore-gcc-toolchain/tree/main You can find last build in the Release section |

@go2sh I suppose the foundation already made can be used as well for supporting the TC27x, right? They are the target chip I'm using currently. |

Great to hear, currently I'm tweaking your branch to get it working to the TC27x evaluation board I have in hands, I think it is time to add proper device tree for this soc even though is very minimal, are you generated the dts files for the TC3 target using any automation script or by just using the information from the reference manual? Thank you. |

I don't think it can be built with the TASKING compiler, used by AURIX development studio. You need a GCC/Clang compiler. Personally I used the open source tricore-elf-gcc EEESlab/tricore-gcc-toolchain-11.3.0. You can build the compiler yourself, or grab a pre-built bundle from my fork: https://github.com/NoMore201/tricore-gcc-toolchain/releases.

@cperkulator I hope too, but having worked with Infineon MCUs in the latest years, Infineon doesn't seem to be the kind of company to easily share its work to the public under an open license. Happy to be proven wrong of course. |
