  1. That'll teach me to do math after a dose of Norval - of course you're right.
  2. Two 4V 2.6AH batteries in series, connected the input of the 4015. Output goes to GPIO, use at least two ground and two hot pins. Before connecting set the 4015 to output 5.1V with a 1 ohm, 10 watt resistor across the output terminals. If you have a big enough resistor (20w at least), use 0.47-0.5 to simulate a 2 amp current draw. You can get 2+ hours out of this at full load, more at reduced draw. **Edit - this math is wrong, was corrected few posts below*** Remove your dummy load and hook up the Asus. I use a powerbank with a Little Pi Zero as a portable media player and headphone amp (not using Armbian for this). Powerbanks are usually quite variable in quality, so you might get a lemon. The 4015 is at least reliable.
  3. I understand that almost all problems can be fixed by users, but I also think the community shouldn't be fixing basic problems in a 'second' version. It's okay to have missed stuff in the first version, but they should be listening to makers if they claim to have been working with them. Thermal and power issues are basic usability concerns which the S version should have fixed, the only 'fix' was to specify a 3A cable which is not possible in micro-USB form factor, the required wire gauges will not fit the connector and even if they did the pad sizes on the mating parts is insufficient. I never had an issue with mine either in terms of power even though I am using it in a 24x7 application with micro-USB. The (temporary) supply is 4A, with one port for the hub with HDD and other for the Tinker. But a lot of newbies will assume that the design is fully thought through, which it isn't and requires some level of hardware hacking to use it to its fullest potential - either a bigger sink, or a fan of some kind, preferably both. I do agree the eMMC is a nice touch, and for audio the I2S slave and master mode is a great addition - if they can get it to work correctly - even basic sound doesn't work correctly either using internal or external cards in all distributions even one year after launch. There's no hardware acceleration of the video output for any apps except the RK Media Player, which isn't exactly a feature-rich media player. Basically they made a decent bit kit, but there's a lot to do to get more out of it. My humble opinion is that they had some more issues that should have occupied some attention - they had the opportunity to address them, and they didn't. My bigger worry is that these basic usability issues keep the board adoption at a low level and the company eventually ditches the project because not enough people are jumping on the bandwagon, even though the reasons are of their own making.
  4. First time hearing of it, looks like another misadventure by Asus and will end in a badly coded TinkerOS which cannot install even basic stuff like Samba properly. I would really have liked to see USB 3.0. The additional performance of the 3288 is lost in thermal throttling (which they have done nothing about) and the very strange choice of micro-USB for power input - which also they did not do anything about except specify that the cable needs to carry 3A - yet to hear of a possible candidate. None promise more than 2.4A, and most of them can't even do that. They offer OTG support in the micro-USB port but that's the only way to power it, and no PC will give 3A on a USB port. It's typical of Asus to continue their knee-jerk launches without fixing the underlying problems in the architecture. I know they're not rocket scientists but come on! I do have mine running stable 24x7 but that is only with a top quality cable and a fan blowing air directly across the board. Oh, and because I'm not using their stupid OS, I chose Armbian.
  5. Thanks - I'm aware that the slow speeds from Debian is not your issue, I was also blaming Debian. It was probably temporary. I'm not interested in 5G wifi as I have a good router for that. It does have a 2.4G band, but my apartment goes to 37C in summer and I wouldn't want it to overheat (I've had failures in previous hardware). Actually I have another cheap router to provide a 2.4G signal but the Tinker took the LAN port it was using so I don't have any more left. Which is why I was keen for it to do this. My Rasberry Pis need the 2.4G band, as you can tell. I do have another issue. I have a couple of USB drives connected to the system and configured to mount at boot using lines in fstab, and then the mounted directories are shared using samba. There is also spin-down using hdparm, so the drive UUIDs are referenced by a few system services. This forms the backbone of my home cloud. Yesterday I removed one drive and the system stopped responding and wouldn't boot. I couldn't figure out what it was, but it seems that the system goes crazy if one or both drives are missing - or even have some small timing issue or loose USB cable at reboot. The disk access light (amber) flashes but the green read light does not, and the system shows a blinking cursor on screen. I read that by pressing "shift" at startup I would get the loader, but nothing happens - the cursor keeps blinking along with the amber light. Is there any simple way for the system to ignore the drive connection (for all services), or is this something I will have to put up with? I tried setting "errors=ignore" at fstab, but it doesn't really do anything at all. For time being I simply reconnected all drives and used one alternative SD card which seems to work sometimes. I have no way of knowing if the system will behave when rebooted. Thanks for any input. I am not yet fully comfortable with the way Linux works - in Windows (or even my routers which run some form of Linux), drives can be plugged or unplugged at will and they mount and unmount automatically, and cause no issues while booting.
  6. Hello Igor, It is only with Debian site. I am able to download using wget (for example) for LMS-package at 3-4MB/s. But all downloads from Debian site are very slow. Network performance is not an issue far as I can see. Yes, it was with first boot and try to run apt-get update/upgrade that I noticed the issue. But later when I get Samba and Transmission packages, it is slower than (for example) what I saw earlier with Ubuntu. Wifi is disabled - I think permanently because its only job was to get me a 2.4GHz hotspot which I am not able to get stable - but I don't think that's Armbian exclusive issue. I did notice TonyMac's post and the whole thread so I have kind of stayed clear of trying to play audio. I will wait till the audio is sorted, I don't mind working USB audio or line out for basic web/clock radio application, if and when that becomes available but like I said it's not a big issue. Tinker OS is very poor in so many ways it's not even funny, I couldn't set up Samba at all so I wiped it. I am probably sticking with this install now that I've got 99% of my wishlist fulfilled. Really appreciate all the help from you. Very kind of you
  7. Thanks to Igor for pointing out Debian. I made a stable Ubuntu version first and then copied the config files over to Debian. LMS runs fine and I can connect to the server and add music. All other features were quite easy because of existing config files. Waited a while and I could download Transmission and Samba now, though server speed is extremely poor - topping out at 40kb/s like in the days of modems. Debian is definitely not baked properly. I hope at some point there will be some kind of audio output possible (heads up, TinkerOs and Android for this board both have working audio over HDMI - no idea about the 4-pin jack on the board itself as I don't have a compatible splitter). Armbian is more powerful as server though, so I don't mind the lack of audio output. Hope one day to have working 2.4GHz hotspot which is now the only missing link but not a massive issue.
  8. The apt-get update command does not work either, something about missing resources. Would it help to put a fresh image on the card and try again?
  9. Thanks Igor, but the problem is a bit bigger than that - the Debian repository is not responding to the requests for simple stuff like Samba and Transmission. I can *probably* kludge my way around the console to get things done (seeing as there are more help resources for console than desktop). I will try your link though. I'm going to try again and see if I can download the packages offline on a Windows machine and install them without the automated DL. But I would also want to see the LMS problem get fixed on Ubuntu because that install is 90% there, only printer, scanner and LMS are left.
  10. Hi My lsb_release outputs Ubuntu Xenial. Should it be any different? Edit: I downloaded Stretch but there is no desktop, only console/ssh. This is going to be a long day... it does not mount the USB drives at all, I can't set up the hot spot without a GUI and I have no idea how to set up sharing without seeing the drives. I had maanged to even get CUPS working yesterday but here I'm totally lost. I do get the Logitech web interface now, but I can't select music because the drive isn't mounted. And the console is a black box to me - so it looks like I'm heading down to a dead end again.
  11. Hi http://sprunge.us/jEVN I am not sure which it is, but it's the link that pointed me to mainline build.
  12. Hi I was struggling to find the right package for my Tinkerboard. I needed a reasonably powerful 24x7 appliance that could provide torrent downloading, wifi hotspot, a shared network drive and a LMS box. After trying out the Asus effort and DietPi - both with severe issues) I landed on Armbian and it seems to have everything going for it but the LMS install just does not work. I am a Linux newbie, I know my way around Windows and a GUI, and used the instructions here and a few other places to successfully set up the hotspot and the sharing and automounting of large USB drives. It took me the better part of 6 hours just to figure all of that out (jus so you know how useless I am at this). I am struggling with Transmission as well, but I got it to work in fits and starts so all hope is not lost. Unfortunately with LMS I am stuck. The package installs fine but will not start. I am assuming the installation is unsupported on Armbian, is there any way I can make it work? This is what I did: 1. Download and install armbian (mainline kernel) 2. Point my browser at the 7.9 beta builds of LMS nightly 3. Install the package using apt-get and pointing it at the downloaded file 4. Tried to connect using the web page. The _safe service seems to be running (checked using HTOP) but the main service does not. It may have something to do with Perl incompatibility, or it may not. I'm a bit out of my depth here so was hoping for some pointers. When querying the service it says: This presume this means that the service should show up in HTOP, but it doesn't. Not sure what to do next, and I would really appreciate any help that is offered. Thanks in advance!
