  1. Librecomputer Renegade RK3328

    Up to 4 GB RAM, nice. I don't believe the RK3328 (Quad core Cortex A53) is capable of pulling the kind of power the RK3288 can, so that shouldn't be as terrifying a prospect on microUSB (and to be fair, I've been running my Tinker Board on microUSB for over a week just to see what would happen, even plugged my cell phone into it). The campaign says this was done in conjunction with the Firefly board designers, explaining the name I saw floating around for a while. It's using a Rockchip PMIC, from the look of it. Probably RK805 like the Rock64.
  2. ODROID UART debug connector

    I got the connector housings and terminals in, and remembered immediately why I always try to buy this stuff assembled. It's a lot easier when it's not my money I'm spending on things. I made a simple wired harness nothing to really see there, the spec for these is 22 AWG, but I think if you've a steady hand with a solder pen you can go 20. The contact with the pin is far better than USB as well, so these could most likely serve as power. Now, I also like to make things simple when I can, so I did this: I am certain it is easier to do this on wires, But I couldn't resist. I might look at a small PCB to make it FTDI Friend compatible. Yes, I know that is a FriendlyARM board, but I realized I didn't have a 1.8V UART laying around...
  3. Web page(s) redesign

    Well, I do agree we need to stick to web page topic, the other stuff is an elsewhere conversation. So I spent some time in the documentation github, I saw changes go live instantly on the documentation page, nice. What is the rate of update on the webpage itself? I added the ethernet issues to the potato board notes, it wasn't there initially, but was several hours later. I like the GitHub --> Web page link, that allows for direct community contribution via pull request, and allows for rollback of mistakes.
  4. Web page(s) redesign

    I agree, but wish we had a way to "document-ize" the tutorial after all the discussion. You get 40 pages of talk on a tutorial and it's easy to miss the important parts. Yes, there is. I think we run into trouble that there aren't many maintainers to begin with, and we range from " This is good enough I don't need feedback" to "I want 100% absolute direct democracy on every decision". This is difficult, and there are pros and cons to both.100% direct democracy does quite literally mean nothing gets done in a reasonable time, but everything will be more stable. "Good Enough" gets you more bugs, but also more on-time releases and a sense that you're "doing something" to the general public. (See the criticism Debian gets about their definition of "Stable") There is one thing I can say that is hard to dispute: I can test something pretty thoroughly on my hardware in my laboratory with my equipment. That doesn't mean it's going to work for anyone else repeatably. So I test, and I commit the changes. My changes are immediately live, there is no means to "trial" a change. This is a discussion for another thread, but we should have a stable "release" branch that only gets updated for bugfixes. Then our download page would have "Stable Release" and "development" images. People want to use dev images? Ok, but know that a 5.37-beta release may not be stable, even if it is a legacy kernel/etc. For the Website: I think a CMS is best. However, if the primary maintainer of the website is not fond of that idea, then a set of templates and a github would be a wise alternative.
  5. Properly powering the Tinkerboard

    Not if you keep the supply at or below 5.25 volts
  6. Properly powering the Tinkerboard

    5.25 V is the spec maximum for USB devices, and the Tinker Board 5V input rail goes straight to the USB. Also, every interconnect in a circuit is a tiny resistor, and results in a small voltage drop. The higher the interconnect resistance, the higher the drop. Even powering through GPIO you are only using 2 pins to carry several amps, which is still not incredibly ideal, even though it is hugely better than using the microUSB. TL;DR: If you have 5.0 Volts going into the tinker board, you will not have 5.0 volts at the USB connectors, ethernet, etc. I use 5.25 as it is within specification and allows some immunity against hot plugging current-hungry USB peripherals.
  7. [RfC] Make Armbian more IoT friendly?

    Well, if you have 16 or 32 MB of storage, that might be important. ;-)
  8. Rock64 nightly image

    I built a cosmic ray detector once, good chance to play with photomultiplier tubes. However it's hard to be sure unless you've tuned it right, random gamma events from the long decay chain of Radon, for instance, can make a mess of your data and make you think the cosmos is even noisier than it really is. The important part about them though, is that they don't come from here, they also don't come from the sun, by and large. And bit flips in extremely high density media has a lot more to do with the probability of an electron existing where you think it does, or not. Google things like "hot carrier injection" (Safe for work, I promise ), and electron tunneling. Just because we will it to be so with our machines, sometimes nature gives us a hand gesture we wouldn't want our children to see. And sometimes, the carriers don't stay "stuck" in jail where they belong.
  9. C code for 2 line x 16 char LCD

    Thanks for the reply, I was wondering about the driver. ;-). Even in my test equipment I run them 4 bit, it's just easier wiring. Sent from my Pixel using Tapatalk
  10. C code for 2 line x 16 char LCD

    2x16 I2C interface? Interesting. I was confused until I saw the picture, the HD44780 interface for those now has a kernel driver. I need to look at it and see if it can be run in 4-bit mode or if it has to go 8-bits wide. I've been lazy, I have a drawer full of the parallel displays... (good and cheap, and I'm usually using Cypress PSoC 5 controllers with tons of I/O)
  11. Info: Rockchip are phasing out sales of the RK3288

    Oh my, have they fixed all the reboot hackery? Also see: Giant Heatsink. And no, even in automotive where last time buys are common, no one is stocking to support "up to" 2 million pieces without guarantees that the parts will be used. I wonder if that vendor had a falling out with Rockchip.
  12. Librecomputer Tritium H3

    In terms of "Le Potato" yes, Libre Computer is supporting development actively through the same team Amlogic is using to get their SoC's mainlined. It has been nice seeing the improvement from kernel to kernel, and they've been responsive to issues/feedback. If that's the rule for how they proceed, then I have some confidence in the boards barring any hardware mistakes. I think it would be best to verify the voltage situation, as I saw a few oddities on that portion of the schematic concerning layout and labelling. (Nothing "wrong" that I remember , but some labels and such) Sent from my Pixel using Tapatalk
  13. Nanopi M3 / S5P6818 boards

    I'm an old dusty FriendlyARM user, it's actually what brought me here. I did initially avoid these because of unknown SoC support, going with their H3 boards instead because Armbian supported them. The boards look interesting, and yes, no micro-USB
  14. Librecomputer Tritium H3

    There is an H5 one as well, correct?
  15. Web page(s) redesign

    I have thrown myself out of the forums at least 6 times today by clicking on the "Armbian" banner image.
