Hello,
I just found this interesting document:
https://fastcode.io/2025/08/30/the-69-billion-domino-effect-how-vmwares-debt-fueled-acquisition-is-killing-open-source-one-repository-at-a-time/
In a summary, if you expect anything cool from broadcom: dont.
go go go reverse engineering!

We should also know the official stance from Broadcom and RPI Foundation :-)
Thanks :-)

For a good start you can contact Broadcom and RaspberryPi Foundation,
introduce yourself as Apache NuttX RTOS developer that want to port
NuttX to rPI boards, and just ask if DataSheets are available :-) We
will know then first hand if this is possible or are there any
problems / requirements :-)
You can ask for 4B and probably Zero-2W SoC documentation these seems
most popular nowadays :-)
Thanks :-)

Hi Tomek,
Thanks so much! I actually hadn't thought of that, maybe we could ask for
help from the foundation. Do you know who's the best point of contact for
that?
I know Linux must have received the datasheets to make Raspberry Pi OS. No
offence to NuttX, but Linux is pretty popular in comparison. If Broadcom or
Raspberry Pi would release us some information that would be an immense
help. I suspect there was some kind of deal with the Linux group but I have
no idea. I believe even QNX didn't have access to the datasheets and rather
just reverse engineered the Linux drivers.

I2C still needs some work unfortunately. However, I agree with you
generally. Personally, I think HDMI, networking (including WiFi and BLE)
and some kind of interaction with storage (eMMC or SD card) are the most
important. Unfortunately, those are likely going to be the most difficult
because of the lack of documentation on the peripherals. It is definitely
not an impossible task, but it will be challenging. Hence my request for
creating the new project roadmap, so maybe some discoveries can be
documented there and more eyes can get on the RPi implementation.
The lack of documentation is a real pain, and known issue for years in
many areas, but some vendors are especially famous for that.
Considering someone wants to create Open-Source drivers for free and
bring customers to the vendor.
Maybe we could ask Apache Foundation for help in obtaining required
datasheets? :-)
