Isn't that an issue when you do a Windows Update? It is. for me with my similar little device - or do you have additional storage attached? Also, will it pass on all sample rates, or is it limited? I don't use Windows. HQPlayer OS image is 1.5 GB of which about half is empty. While NAA image is only 261 MB. I have a minimal Debian Buster installed on some of those (just things needed to run HQPlayer Embedded) and the OS and HQPlayer Embedded takes 3.8 GB (with bunch of extras for debugging), and the storage has 23 GB of space left. semente and AnotherSpin 1 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
Popular Post Miska Posted April 13, 2020 Popular Post Share Posted April 13, 2020 There tend to be couple of challenges with ARM based platforms. One is that they lack capability to describe their own hardware structure and connections. So Linux kernel needs a so called device tree file that describes this. This needs to be done by each hardware vendor who designs some kind of board around an ARM SoC. They know how things are connected together. Different hardware vendors have different quality level and response time of their Linux kernel support. This leads to the second problem, which is that many times the available supported kernel is pretty old. In worst case which is also rather usual is that the kernel matches the Android kernel which is ancient. This means having kernel version 3.14 (from year 2014 - 2016), while Linux kernel is at the moment on version 5.6. Intel/AMD platforms don't have this problem because they have a firmware system called ACPI that can describe the hardware configuration to the OS. Hardware manufacturers only need to place information about the hardware in their BIOS (sometimes they have bugs on this too, though). But they don't need to work on the OS at all. Then you can just pull very latest Linux kernel and start using it. Sometimes they just issue BIOS updates to fix bugs in their ACPI data or similar, however this is independent from the OS. 4est, Jud, The Computer Audiophile and 3 others 2 4 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Please make sure your BIOS is largely at default settings, IOW it is trying to boot using EFI and not legacy. And that USB storage is enabled as a boot device with priority over internal storage.

Thanks. If you search for example Amazon UK for the CPU type; "x5-Z8350" you can find some devices. For example this looks like Apple TV: https://www.amazon.co.uk/Pro-x5-Z8350-Graphics-Computer-Bluetooth/dp/B07D9YX3W6 (2 GB RAM) https://www.amazon.co.uk/Windows-x5-Z8350-Graphics-Desktop-Computer/dp/B081DR8CVN (4 GB RAM) But note that some of these may have a small and loud fan hidden inside, so be careful. And many likely have plastic cases unlike the one I recommend. The device should be passive cooled so that it doesn't make unwanted acoustic noises. It doesn't need much cooling, but it still needs heatsink to keep the CPU cool (like RasPi4 too). Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

And, it does seem to be fanless, so it ticks that box. I can't seem to find a cheaper box without windows, which is a shame as I would just be installing the NAA image instead. Yes, that's another option. There seem to be at least couple of possible options. I don't have any of these, because I use the UP-Board one (practically made by ASUS). Unfortunately you end up paying some amount of "Windows tax" on the price. But OTOH, you can leave the Windows on eMMC and boot NAA from USB memory stick or microSD. Windows is probably horribly sluggish on such small memory and low power CPU. But for NAA running my image it is perfectly fine. In the picture the Wintel Pro uses 5V DC power, hopefully feeding it straight to USB VBUS too. The iFi PSU is probably a bit too weak for those. For 5V I'm using a Meanwell medical grade 5V 6A PSU brick, the model that has floating (two pin non-earthed) mains connector. There is also 12V model of the same with just lower current rating (because Wattage is the same). Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

You need my software to make turn it into a NAA. From my web page you can download bootable NAA images that include OS and the NAA software module, all in one. You dump such image for example on USB memory stick using tool like Etcher, and then boot up the device using that image. And that's it. When there's software update, you dump the new version on a stick (same or different) and boot up from that one.

I am thinking of using one of the UpBoard variants for this project. I saw your post that you use one for running the NAA with the Linux image. I was considering one of the more capable versions that I could run WIN 10/64 on if there would be an advantage to this approach. I have had good results with ASIO drivers for my desktop system but had not previously considered the Win/ASIO approach for the NAA for my main system. No, there is no advantage, but a big disadvantage of using Windows for NAA. Windows just adds massive amount of unnecessary bloat. My bootable NAA image is very minimal OS custom built for this particular purpose. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Current NAA image is about 300 MB, so let's say 4 GB stick gives you plenty of extra capacity. Speed of the the stick affects the time it takes for the system to boot up. Since NAA image runs from RAM, everything is read at boot time and then not accessed after. RAVENNA version of HQPlayer OS is the biggest image, which is now at 1.7 GB, of which about half is empty. So for that purpose too, 4 GB stick would be fine. Difference is that the HQPlayer OS image runs from the stick, but the speed mostly affects boot time, because after boot up the amount of access is minimal. You can also run either one from a microSD card, either using a USB adapter or your computers microSD or SD card slot if it has such. 16 hours ago, dmccombs said: Can you point me to the latest image for the atom computer and NAA software?

Most distributions have problem with NAA and PCM (751/768 >> 60Mb ethernet flow with some clics and drop out). I believe I have all USB ethernet drivers enabled, but I can check. However, I would strongly recommend against using USB for networking or music content storage. It causes lot of unnecessary CPU load. RaspberryPi4 is first that uses the on-chip ethernet controller and it is much better to use that one than a USB one. With USB connected one you easily end up with problems that RasPi2/RasPi3 had with their USB connected ethernet controllers, ending having clicks and pops on the playback. Transformation between ethernet and USB packets is unnecessary work. Ethernet controllers should be connected directly to the CPU data bus, or alternatively to PCIexpress. Not to anything else. Also pay attention that the ethernet controller has proper DMA access support and hardware offload for TCP/IP checksumming and such. If you want an external ethernet controller, you should use a Thunderbolt one instead, it is essentially same as PCIexpress connected one.

Yes, it is USB Type-C connector, but it has the lightning logo to indicate Thunderbolt capability. Type-C connector is special in a way that it has multi-role support. In addition to USB, it can function as Thunderbolt or DisplayPort connector if the hardware supports it. So just having the connector doesn't mean it would have Thunderbolt or DisplayPort functionality, both the host and the device need to support such for it to work. Thunderbolt functionality is thus indicated with the lightning symbol. Essentially these change completely meaning of the connector pins, and only the physical connector itself stays the same. Apple makes Thunderbolt - Gigabit Ethernet adapter. 9 minutes ago, ambre said: Due to use of another big powercord there hardly space for using regular ethernet connector. What is your advice ? Dump the special powercord? Yes, I would dump the special power cord and use regular one and the built-in Ethernet. There are also thin round CAT6 UTP cables and flat ribbon CAT6 UTP cables that have also relatively small connector, so these may be easier to accommodate in tight spaces.

There's no SSH because it is not very useful and for security reasons because it would be bad idea with a default password. OTOH, drivers need to be built specifically for the kernel they are being loaded on, so you cannot download a driver from another kernel. In addition, many distributions for RasPi are 32-bit, while my OS images are completely 64-bit. This would make anything built for a 32-bit OS version not work.
