Porting into TriCore Environment

Post by SUBBU3881 » Mon Dec 04, 2017 11:15 am

Hi,
Can any one help me in porting micropython for the TriCore environment on one runable of AUTOSAR. I am new to python but have basic knowledge on python. Now my task is to port the micro python into TriCore environment. Please, suggest me how to port the python into TriCore Environment.?


Thanks and Regards,

It might help, if you provide some links for the technologies you mention to give some context and also, if you explain why you have this requirement and what you ultimate goals are.

Also, please note that to port MicroPython to a new MCU / architecture, knowing Python isn't enough, you need to know C/C++ and have a good understanding how microprocessors generally work.

Hi,
Thanks for the response.
As per my project, I need to port micro python on to existing project which uses Infion's TriCore controller. So, already a C project is running on the microcontroller. Now I need to port the micro python along with the C project. Then as per the application I need to write test cases in python for that existing project. Here, I needed for porting micro python on to micro controller. Suggest the way to port micropython on tho micro controller environment.


Thanks and Regards,

Describe in more detail your application’s architecture. You haven’t given any real detail.

Hello,
Actually I have the board having Infineon's micro-controller and one automotive application is running on it. Now, I need to port micro-python onto that board. Before porting, I needed to flash micro-python interpreter in to flash. What is the procedure to load Micro-Python's interpreter on to that board. Please, suggest what are the thing I should know before porting.



Thanks and Regards,

Why do you think that Python needs to run on the TriCore controller to be tested?
Usually, you would use another hardware that simulates the environment in that the controller board will run in the real world.

Thanks for the response.
Currently in my project we are you using AUTOSAR on tricore controller.
Actually my task is to port micropython interpreter onto tricore controller architecture. So I need support to port micropython to tricore along with AUTOSAR.

How can I cross build the micropython source for tricore.?


Please respond as soon as possible.

Thanks and Regards,

I would suggest you have a look at how to build e.g. the standard MicroPython and the one for PIC 16 bit.
The PIC is currently probably the most different from the 32 bit ARMs.

https://github.com/micropython/micropython
https://github.com/micropython/micropyt ... s/pic16bit

The rest is just a lot of work...

Dietmar

Thanks for response. As per my project, MicroPython not needed for booting the board because already AUTOSAR is running on my board. I just want to add cross-compiled Micropython Interpreter onto flash memory. I gone through the source files in "/minimal" directory in micropython source code, and it is having STM controller's UART and GPIO details also, are they(uart and gpio files) necessary for generic Micropython Interpreter.? So can you please help me in this regard.

Thanks and Regards,

You should replace the STM UART and GPIO stuff with code appropriate for your environment. They were added just so that the minimal image could be tested on real hardware.
