[riot-devel] Fwd: 64bit and multi core support
Dear RIOT team, Thanks for RIOT I personally think it is GREAT! We are considering using RIOT on our ARM v8 64bit multicore (SMP) hardware. The platform requires 64bit memory addressing (DDR is at higher than 32bit address range). We would appreciate if you could help us understand if using RIOT is feasible by answering below questions: 1. Does RIOT support 64bit memory addressing? For example if I build “hello-world” sample project on native platform then 32bit binary generated. Is it possible to build it for 64bit? Have this been tested? 2. Does RIOT support multi core? I.e. scheduling threads on different cores, synchronizing threads running on different cores? Have this been done before? Best Regards, Alex -- Alex Mavrin ___ devel mailing list devel@riot-os.org https://lists.riot-os.org/mailman/listinfo/devel
Re: [riot-devel] Fwd: 64bit and multi core support
Hi Kaspar, Yeah this is very interesting project!:) It is custom board with multi core ARMv8 (64bit) CPU (SMP system). We need some simple, very minimalistic OS we could use for hardware testing and bring up. Main use case would be sequential HW testing (e.g. registers read/write, interrupts handling, calls to trust zone, etc.) on multiple cores. We also look at minimizing effort needed to port this OS if newer hardware is available. In addition, we are very excited that C++ is available on RIOT! We do consider using Linux. However, we would prefer something basic. So again this is the list of questions, we hope you could help us answer ;) 1. Does RIOT support 64bit memory addressing? For example if I build “hello-world” sample project on native platform then 32bit binary generated. Is it possible to build it for 64bit? Have this been tested? 2. Does RIOT support multi core? I.e. scheduling threads on different cores, synchronizing threads running on different cores? Have this been done before? 3. If using C++, can we use exceptions? Is it possible to use C++11 if compiler supports it? Best Regards, Alex On Thu, May 7, 2015 at 4:01 PM, Alex Mavrin alexeymav...@gmail.com wrote: Hi Oleg, I really appreciate you forwarding this!

Re: [riot-devel] help
Hi, This is often called firmware update or OTA for (firmware) over the air. We don't have support for this yet, but it is planned, and there is some information in the wiki (look for OTA).
