Not yet. It's on the list of planned modules.

Hi,

Not yet. But it is in our backlog.

I've prepared a simple script to upload the built MicroPython firmware (firmware.bin) to the board. It can be simply used by executing:

@loboris: Do you mind if I add this script and the related Freescale executables to the Pull Request for the ARCH MIX board?

You can add it, of course.
The script could be improved with some more error checking and the windows version could be added, which I intend to do later this week.
The script can be used with any RT10XX board, not only ArchMix, if the method to enter the ROM bootloader is available (I think it should be available on all boards).

BTW, I've finished the FreeRTOS version of the mimxrt port which has many advantages on such a powerful microprocessor.
It works great (as far as I've tested it). I'll give some more details after some more testing...

That's indeed interesting. There is already a Zephyr port for mimxrt boards. You might have noticed it.

I2S and SP-DIF is on our list for new modules.

If someone is actively working on I2S for the Teensy I can offer to help them with the implementation. I did the I2S implementation for the Pyboards, ESP32, just recently the Pico. If no-one has started the work, I could take it on.

As far as I know no one is currently working on it. Your support is highly appreciated.

That would indeed be fine. Please make use of the nxp-driver lib. Examples can be found in the NXP SDK for the respective MCU. You can download it from the NXP web site. https://www.nxp.com/design/software/dev ... presso-SDK

Thanks, look forward to your results! Please post updates.

Is there any timeline for I2S completion? I imagine that it will take a month or two. If that fits with your expectations I'll get started. Is the Teensy 4.1 the best hardware to develop with? Digikey/Canada has them in stock.
