  1. Hello, I recently got a Nanopi M4v2 on which I installed Armbian Buster current and updated the system, including kernel. After a few hours the board would crash, requiring a power cycle. Aftet reading this thread I decided to try a fixed frequency, so I left it at 2GHz. With a fixed clockspeed I ran stress tests, several runs of sbc-bench, browser benchmarks, used it to open documents in Libreoffice, watched videos using the browser, etc. and it was totally stable for over 5 days straight. I only had problems with Chromium crashing, but Firefox (or equivalent) worked fine. I changed the max and min clocks to defaults and it locked up about 4 hours later. The board was working headlessly and I accessed it remotely using xrdp or dwservice.net. I don't have it connected to UART at the moment because I don't have another computer nearby to connect it to where the board is placed, but if it helps I can find a way to connect it and give you the output.
  2. I connected the board to the in-wall USB charger with no monitor attached, logged-in using ssh and ran the test again. The charger seemed solid delivering 5.12V@2.4A I overclocked the CPU to 2GHz and power consumption went up to 2.71A (with USB disk attached doing full read and s-tui stress test), voltage remained stable @5.12V. So this Leviton in-wall USB charger seems ideal to power 5V SBCs.
  3. I just got my Nanopi M4v2 today and ran a few quick tests, about a week ago my USB power meter arrived also. The first test was powering the board using a Macbook Air 29W USB-C charger and running s-tui to put a full load on the CPUs. The voltage drops to 4.5-4.6 when the amperage goes above 2A. I let it run for a while (about 10 mins) and when a came back to check the board had rebooted. This power adapter is not suited to power this SBC Next test was using a PoE to 5V USB-C adapter rated for 2.4A. Again I ran s-tui and let it go it's thing. After about an hour or was still running. Add for voltage this power supply actually increases voltaje as amperage goes up. It starts around 5.08V with ~400mA power draw and goes up to around 5.26V work the board at full load. With an hdd connected to the USB doing a full disk read and s-tui running I get a max draw of 2.3A with some 2.42A peaks. Tomorrow I'll try the in-wall charger, as right now I can't connect a display near the outlet with the charger.
  4. I bought a set of Leviton T5632 in-wall USB chargers before I even thought of tinkering with SBCs. The spec sheet says it delivers 3.6A@5V, so I thought it should be enough to power a board and a couple of USB disks. Has anyone used a similar device to power an SBC? I still don't have my device and I don't have a USB power meter at hand, when I have them I'll update this. I bought a set of 3 for about $25 off eBay, so price is decent. Here are some pics of the insides in case anyone is interested.
  5. Hello, what's the disk space needed to seed the torrents? On a side note, would creating a repository mirror also help?
  6. Hello, I got the itch to experiment with Linux on ARM. I tried to get an Odroid N2+ bit seems to be unavailable everywhere. The best thing I could get at a reasonable cost was a Nanopi M4v2, it'll arrive in about 3 weeks. While I wait I remembered that I have an Ouya laying around and I asked myself: Is it possible to install linux on an Ouya? Searching the internet there are very old guides from 2013 to install ubuntu, had the situation improved? Anyone here tried?
