  1. I got it fixed! As it turns out, I was trying to work on multiple SBCs at the time. One of them, the Firefly RK3399 requires that it's MMC be modified via USB-C using a propriety program that requires root privileges. In my infinite wisdom, I decided to run it in an apparmor confinement cell -- not a proper totally virtualized machine. So what happened is that, in spite of being only given a minimal allowance of access, it some how caused my computer to have persistent Micro SD cards (/dev/sdX). Then when I plugged a Micro SD card in it would identify it as /dev/sdX1. There were
  2. Hmmm, I'm having a bigger problem with my main Linux box then just a failed SD boot. Hold still. I'll reboot.
  3. Here's what I get when trying to boot (data is from my serial adapter): I2C_WriteByte nack returned I2C Device Address Write Abitration Error I2C_WriteByte nack returned I2C Device Address Write Abitration Error I2C_WriteByte nack returned I2C Device Address Write Abitration Error I2C_WriteByte nack returned I2C Device Address Write Abitration Error Wakeup Sub CPU 1234567 CPU Wakeup done!

  4. Cool, I hadn't thought to check that because I assumed, perhaps foolishly, that being a new SoC it would need a "special" kernel if it supported plain old linux. My bad. What's a better place for information on Rockchip SoCs? Thanks!
  5. Recently, a new SBC, the Rock Pi S by Radxa, was launched. Here's it's wiki page: It's a 4 core A35 design. I'm debating getting one, but I can't find any information anywhere as to whether or not it's supported on Linux, or Armbian. Of course, if it's not listed in the download section it's not supported, but there's a difference between, "I need to add 100 lines of code and it will work." to "Geez, I need to redesign most of the Linux kernel after pulling my hair out." I did search the sunxi wiki and the local armbian wiki without success. A
  6. @codnoscope You need to place more load on it then that. You should get all the USB ports loaded down. A HDD is good (unless it is externally powered), I'd hook a cd/dvd drive to the USB 2.0 ports. The USB C you could charge a phone or something on it using an adapter cable. Then you cat the HDD into /dev/null, write a cd/dvd from a file on the internet which you live download, play an audio file from the speakers, and load the processor down with stress-ng. Watch the processor's speed the whole time and verify the burn. I know that that seems outrageous for a running system, bu
  7. I was writing from memory. Let me read the exact details of the board. Docs can be found here: I was referring to the power delivery schematic in "Firefly-RK3399_V10_SCH_(2017-2-8).pdf" on page 4. The 12v 2A power supply is connected to several bucks (fet type), and a Mosfet. A SY8113B capable of putting out 9W total, 3V at 3A with 1W power dissipation to the M.2 slot. I have read (sorry, I don't remember where) that the M.2 slot is rated at 10W. 9W - 10W = -1W. A 12v fan switch at 3.6A. I do not think I have a schema
  8. @TonyMac32 I have bought a Firefly-RK3399 from firefly ( ). I did not realize it at the time of purchase, but the Mosfets are unable to provide sufficient power for the board plus the USB ports, EDP connector, MIPI-CSI interface, M.2 slot, etc. I really love the IO of the board and want to try to find a way to get it to work (plus I don't have the money to go trying out more boards ). Would your idea help such a board? Thanks!
