James Dougherty contacted us with Gordon Hollingworth from Raspberry Pi Foundation recently :-) We are waiting for response :-) I really hope we can get some sort of documentation and/or code samples to write high quality NuttX port for the big raspberries :-)
Open-Source matters even more in this crazy world. Thanks for interesting article Sebastien! Personally I think we should focus only on vendors that support Open-Source. What is the reason for bumping sales for companies that in the end can sue you for reversing? :D Have a good day folks :-) Tomek On Sun, Aug 31, 2025 at 10:15 AM Sebastien Lorquet <sebast...@lorquet.fr> wrote: > > 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! > > Sebastien > > > On 8/29/25 15:37, Tomek CEDRO wrote: > > No response from #infra@slack, I just sent request to > > dev@community.apache mailing list maybe someone can reply over there > > :-) > > > > https://lists.apache.org/thread/n9y5vrvjm23npwgbr45f7zq5ys5l8dok > > > > We should also know the official stance from Broadcom and RPI Foundation :-) > > > > Thanks :-) > > Tomek > > > > On Thu, Aug 28, 2025 at 9:35 PM Tomek CEDRO <to...@cedro.info> wrote: > >> I just asked question at #asfinfra / slack, maybe someone can help > >> there or recommend someone who can, waiting for response :-) > >> > >> 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 :-) > >> Tomek > >> > >> > >> > >> On Thu, Aug 28, 2025 at 8:45 PM Matteo Golin <matteo.go...@gmail.com> > >> wrote: > >>> Hi Tomek, > >>> > >>> Thanks so much!
