Teensy 4.1 Micropython with ulab

[LeandroFernandes88]

Hello everybody,

I'm looking for all the help I can get.
I've tried a few times and seen on some forums that it might be possible to build a Micropython build with native Ulab in the firmware. But I still haven't managed it.

If anyone has already done this, or knows where to find a link to download the HEX file with this configuration, it would help me a lot.

NOTE: I tried Circuitpython, but I had problems dealing with very small intervals and data acquisition with a high sampling rate. There were also some problems converting array to ndarray. That's why I'm trying Micropython+Ulab.

I'm sorry everyone, I'm a little new to using microcontrollers.

Thank you very much.

@LeandroFernandes88 Yes this is definitely possible.

It's the exact same process as https://github.com/v923z/micropython-ulab?tab=readme-ov-file#stm-based-boards except you do it from ports/mimxrt rather than ports/stm32 and use BOARD=TEENSY41.

If this process is not working the please paste commands and outputs/errors here.

(Flashing will be different too, see the instructions on the download page -- teensy_loader_cli --mcu=imxrt1062 -v -w build-TEENSY41/firmware.hex )

I really appreciate the help.

I was able to follow your instructions and the steps described in the path indicated.
I believe I generated the Micropython firmware .HEX file with Ulab for the Teensy4.1 board

A question that is off topic, I could get also all support and help in: v923z/micropython-ulab#665
