We’d like to announce a Raspbian image for Raspberry Pi A+/B+ update. It didn’t change much, but we’ve made some performance related improvements. It is available for download
RT kernel for Raspberry Pi 2 is in progress, stay tuned!
Any ETA on the Pi2 kernel? I’ve started assembling my quad and the only thing I’m waiting for is the Navio+ to show up. Should I expect to be able to use my Pi2 by the time it arrives, or should I order a B+ now so I don’t have to wait for it later?
@mb300sd Discussion on RPi2 kernel is here:
Well, it's 99% ready, there is only one thing holding us - unstable work of rt kernel with usb driver on RPi2. The problem is that new RPi's USB driver uses FIQ and it somehow causes hangs on SMP system under rt preempt, while the standard USB driver doesn't work on Raspberry Pi 2 at all. I've contacted Raspberry Pi Foundation and opened an issue about the standard USB driver, hope we can work something out soon.
It is hard to estimate when it will be ready.
I guess I’ll plan to order a B+ around the shipping date for the next batch of Navios then. The wait is already driving me crazy
