  1. Just saw this https://github.com/TinkerBoard/debian_kernel/issues/2#issuecomment-316919436 thanks all!
  2. Hi, can someone make a separate thread for recommended accessories for the tinkerboard, specifically heatsinks and cooling? Much appreciated!
  3. Thank you, looks like I'm on the following now: Welcome to ARMBIAN 5.27.170523 nightly Ubuntu 16.04.2 LTS 4.11.2-rockchip
  4. Thanks, I thought I had added it the sources file, but apparently I didn't. I added it and imported the key at the root and it looks like *stuff* is downloading now, wish me luck!
  5. excuse my ignorance, but what's the correct way to get on the development kernel? I'm currently running 4.11 I've tried reading the following with no success: http://www.armbian.com/kernel/ https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-switch-kernels All I could find on apt is: root@hass:~# apt list *tinkerboard* Listing... Done linux-u-boot-tinkerboard-next/now 5.27 armhf [installed,local] linux-xenial-root-next-tinkerboard/now 5.27 armhf [installed,local] root@hass:~#
  6. @lucifercipher thanks, I'm using a PoE solution, I guess I have to run some tests to fully rule out the power issue. Here are the specs http://wifi-texas.com/pdf/WT-AF-microUSB-SL.pdf I have a 2.5amp transformer that I'll try if this issue pops up again: https://www.amazon.com/gp/product/B01F1LVZ0G/
  7. Thanks @TonyMac32, I'm using a reliable SD card. I'll keep monitoring and see if it's a power issue, but I don't think it is. The error I pasted shows something about a possible video error, did that dump make any sense to you?
  8. Just reporting back that my tinkerboard is borderline unresponsive after a 2 day up time, I'm running the 4.11 kernel. Temperatures seem OK and top doesn't report anything out of the ordinary CPU wise. A review of journalctl showed the following: https://hastebin.com/abocuhesab.xml Looks like system services didn't fully recover after that. I'm not entirely sure if this is power-supply related, but perhaps the logs will mean something to someone more informed than I
  9. @Ruslan Dzanmahmudov I ran stress -c 4 for 15 minutes, no failures, temperature got to about 67C. I'm not running a fan, I'm using a 64gb Samsung Evo Select card, and I'm powering an Aotec zstick. I think this is in line with what you're seeing power-wise. Other than the reboot bug, I agree, the system seems pretty stable, but I'm only running home-assistant and homebridge on this thing, it's not being taxed. @tkaiser root@hass:~# sysbench --test=cpu --cpu-max-prime=20000 run --num-threads=$(grep -c '^processor' /proc/cpuinfo) sysbench 0.4.12: multi-threaded system evaluation benchmark Running the test with following options: Number of threads: 4 Doing CPU performance benchmark Threads started!

  10. I'm really not sure why anyone would poop on this board because it needs extra power, that's like pooping on your gaming rig because you need an 800w+ psu... In any case, I'm running this using a gigabit 10W PoE to micro-usb adapter and I can't say I've noticed any issues. If it's of any interest to anyone then I'll be more than willing to take voltage read outs while the system is under load. Until the reboot issue is fixed, at least I can remotely power-cycle the unit via PoE, so that's good too.
