Hi Christian,
This looks awesome! Do you have any interest in adding support for
the i.MXRT1062 based Teensy 4.0 and Teensy 4.1?

the Teensy look like interesting boards. Maybe a bit low on memory.
That would make it difficult to run libbsd on them. The boards don't
have network, so it's not a problem for the network part. But on the
i.MXRT, I also use the MMC/SD stack from libbsd so the SD card would
be a problem.
Just noted: The Teensy 4.1 has an optional Ethernet. So some network
library would be good. But like I said: The target has too few memory
for libbsd. lwIP would be a candidate. But I haven't tried that on the
i.MXRT yet.
Best regards
Christian
It was mean from you to point me to that board. It seems like an
interesting challenge ;)
I've thrown together a quick prototype for a BSP. It's not yet tested.
It doesn't even link the tests yet, because the linker command file
isn't adapted yet. But the BSP sources at least compile without problems:
https://gitlab.com/c-mauderer/rtems/-/tree/cm/20230717_teensy41
If I find some more time and maybe some hardware, I maybe continue to
try to write the linker command file. But I don't promise anything ;-)
Best regards

On the Teensy 4.1, the two memories (optional Flash and optional
PSRAM) on the FlexSPI maybe can be a bit tricky.
These boards would be pure hobby time. I don't think that I will find
enough time to fully support the boards at the moment. But I would
expect that the basics should work with the i.MXRT1052 BSP already.
The 1050 and 1060 family is quite similar. If you want, I can give you
some guidance what would be necessary to support the boards.
Best regards
Christian
