Re: Qemu for TC377
Hi Bastian, Thanks a lot. I have downloaded HighTec IDE from ( https://free-entry-toolchain.hightec-rt.com/) and tried to run the TSIM but no success. In web, I don't see any documentation how to run it. The doc comes along with tsim doesn't explain how to start the simulator. Could you let me know how to start tsim for a helloworld.elf for TC3xx ? is there a Menu in highTec IDE to start it ? I believe it is a cmd tool(C:\HIGHTEC\toolchains\tricore\v4.9.3.0-infineon-1.0\bin\tsim) Regards Sameer On Sun, Apr 21, 2024 at 6:18 AM Bastian Koppelmann < kbast...@mail.uni-paderborn.de> wrote: > Hi Sameer, > > On Tue, Apr 16, 2024 at 02:26:10PM -0400, Sameer Kalliadan Poyil wrote: > > Hi Bastian, > > > > Thanks for the information.

Re: Qemu for TC377
Hi Bastian, Thanks for the information. I thought that I can do some prototyping before the HW arrives. :) Yes I am interested for your bare metal program boot_to_main run it on TSIM. Is Infineon TSIM free? I searched it and I didn't find any download link. Could you please give a link for that if it is from Infineon? s it(TSIM) trace32 simulator ? *https://repo.lauterbach.com/download_demo.html <https://repo.lauterbach.com/download_demo.html> *? This page *https://wiki.qemu.org/Documentation/Platforms/TriCore <https://wiki.qemu.org/Documentation/Platforms/TriCore>* shows SCU is under development. Could you let me know who is developing it ? is it possible to take an existing SCU and modify according to AURIX data sheet? I see that UART is possible to for Tricore like the one developed for ARM versatile platform Here is the link *https://mail.gnu.org/archive/html/qemu-devel/2016-10/msg04514.htm <https://mail.gnu.org/archive/html/qemu-devel/2016-10/msg04514.htm>*l I have aurix development trial version and able to compile a UART project using Tasking compiler and tried to run it on qemu, but I don't see any logs in the qemu terminal as you said there is no peripherals implemented qemu-system-tricore -machine KIT_AURIX_TC277_TRB -cpu tc27x -m 6M -nographic -kernel ASCLIN_Shell_UART_1_KIT_TC277_TFT.elf -serial stdio -append "console=ttyAMA0 console=ttyS0" Also do you know if there is a virtual UART framework to communicate between two Qemu instances or two TSIM instances running similar OS or different OS? I need to do prototype testing RPMSg communication between MCU and SOC using external physical UART/SPI which can be tested using vritual UART using two qemu instances.

This is the closest you will get to TC377 board. I'm not sure if QEMU is the best choice for you, if you want run a RTOS, as qemu-system-tricore is lacking: - peripherals like SCU, SystemTimer that are a bare minimum to run a RTOS - Simulation of time: When your RTOS runs periodic tasks you might get wrong results, as QEMU does not simulate time accurately. The real CPU would see time pass differently than QEMU. We make a best guess using the wall time. I think for now Infineons TSIM is a better choice, as it does not lack the points above. However it has significantly less performance compared to QEMU. If you are only interested in running bare metal software, check out my 'boot_to_main' test [1]. The Makefile [2] shows you how to build it using tricore-gcc [3] and how to run it in QEMU. Also tricore-gdb [4] might be interesting for you. If you have further questions, feel free to ask me.
