Q: If I'm an existing Dianemo customer will I need a new license to get access to Dianemo-Rpi2?
Unless you have already been allocated a trial slot then yes you will need a new license. Dianemo-Rpi2 is our first ARM based product and will require a separate license to our current Dianemo X86 based product. The good news is that you can get a new ARM only license for a special $99 USD price currently.Q: Will the current ARM only license price of $99 USD be available after you launch Dianemo-Rpi2?
The honest answer is we have not settled on our pricing yet for Dianemo-Rpi2. But we do see the current $99 USD price as a special introductory price prior to launch. So we would encourage you take advantage of this pricing now if your interested.Q: How long will the current $99 USD ARM only license offer continue for?
The current ARM only license offer will only be available until we feel we have enough people for the trial testing period. So our advice is that if you want to participate in the trial or want an ARM based NC/Core then you should purchase an ARM only license soon.Q: Will my Dianemo-Rpi2 license work with the final released version?
Yes it will. Any ARM only licenses purchased now are full licenses and will work as they should after we launch Dianemo-Rpi2.Q: When will we receive the first preview release of Dianemo-Rpi2?
We are currently expecting to have the first builds ready for release to preview users in May 2015.Q: Which OS will Dianemo-Rpi2 be compatible with?
Dianemo-Rp2 will ship on Raspian which is already ARMv7 compatible.Q: What CODECS are available for the Rpi2?
Both the MPEG2 & VC-1 codecs are available for all models of the Rpi. The codecs can be purchased from here; http://swag.raspberrypi.org/collections/software
**Bare in mind you only need CODECS on RPi's that will be playing Video**Q: Can I install Dianemo-Rpi2 on multiple SD cards?
Yes you can. Those SD cards will only work on your Raspberry Pi2 though - each license is restricted to one Rpi2. But you can do a bootable image backup of you SD card to your PC's hardrive - this will enable you to restore to your SD card if you need to. You could even have multiple SD cards with a copy of Dianemo-Rpi2 on each that has different configurations - you might do this if you were experimenting with several configs or want to test different 3rd party hardware projects etc. The only limitation is that your license can only be installed on your Rpi2.Q: Will Dianemo-Rpi2 support serial devices?
Yes we will support any USB serial adapters that are compatible with Rpi2. We will also support IP addressable serial servers/adapter such as the GC100 etc too.Q: Will a Dianemo-Rpi2 Core/NC support a local MD & HDMI audio?
While the Rpi2 hardware will definitely support HDMI audio we do not currently plan to support MD functionality on the Core/NC itself. We don't think the performance will be adequate (we may revise this if tests prove performance is not a problem). But since adding another Rpi2 as an MD or as a UPnP Media player is simple and only costs an additional $35 USD we feel that’s an acceptable limitation. Q: Will Dianemo-Rpi2 support MD's?
Yes we will but probably not at first release. We also will almost certainly not support PXE booted MD's for performance reasons - MD's will boot from a local SD card image. Our updater scripts will manage the updating of MD's automatically for you.Q: What hardware will I need?
For your NC you will need a standard Raspberry Pi2 board and a compatible USB Gigabit NIC (you will need both a LAN side & WAN side NIC). Obviously a Raspberry Pi compatible case would also be a useful purchase and a suitable USB power supply (2500ma or greater rated if multiple USB ports used). A 32gb or larger Micro SD card will be needed for the OS and Dianemo firmware. All of these items can be purchased from any Raspberry Pi reseller.
For MD's you will need either a Rpib+ or Rpi2. No 2nd NIC required. Again a suitable case is not required but is probably a good idea and a USB power supply (2500ma or greater rated if multiple USB ports used). A 8gb or larger Micro SD card for the MD OS and Dianemo MD firmware.Q: Will I be able to access the Rpi2 GPIO pins?
Yes absolutely. If the Rpi supports it we want to too. One of the many advantages of the Rpi platform is being able to use all the I/O on the board either directly for simple projects or by using any of the many Rpi expansion boards that are available.Q: What kind of system can be built around Dianemo-Rpi2?
Because MD's (if you use them) will boot from local SD storage and only Athena based UI skins will be supported the average load on the system will be much lower than with existing NC's. There will also be other architectural changes that will improve performance on low power ARM hardware too. Add all these changes together and we are confident that a Dianemo-Rpi2 NC will be able to support an average sized house. Part of the testing process during the trial will be designed to measure performance capabilities for a range of system configurations.Q: What expansion limitations will there be?
The Rpi2 obviously lacks PCie slots so any expansion in the NC will need to be achieved without requiring those. But it does have 40 GPIO pins and both DSI & CSI expansion connectors for all manner of add on hardware (it's full compatible with Rpi expansion boards Etc). We hope that many standard Rpi expansion boards/projects will be integrated into Dianemo-Rpi2 by both you guys and also by us. The Rpi2 also has 4x USB 2.0 ports (although we use one of those for the 2nd NIC). Adding audio/video media storage is easily handled by adding a low cost NAS (or multiple NAS's even) to your LAN for unlimited media storage. Ripping disc based media can be done from a PC or by adding a USB optical drive. So all in all there are few if any expansion limitations that cannot be easily worked around.Q: How many MD/MM's will Dianemo-Rpi2 handle concurrently?
Since MD/MM's will boot from local SD storage and will stream media from LAN based storage like a NAS the load imposed on the NC will be considerably lower. Also there will be no UI's to regen which also removes a large overhead. So our expectation is that Dianemo-Rpi2 will handle these loads comfortably but until we have the Preview underway we can't provide a definitive answer. My feeling is that in reality this will not be a limiting factor for most users.Q: Will Dianemo-Rpi2 support LMS and SqueezeSlaves?
Yes it will. Again as in the reply to the question re MD/MM's above we will need to test the limits of performance during the Preview. Clearly a Rpi2 Core will have a more limited capacity than a big Intel based Core but we expect for the vast majority of use cases this will not be a factor. For the most of the time our big Intel based Cores are barely being used and it's only during regens and PXE booting MM/MD's that there big processors are needed. So by removing these, and a few other performance hogging pieces of code, we can build a Core on Rpi2 that will perform well overall with far less hardware.
