    The Allwinner_H3_Datasheet_V1.2.pdf document mentioned that absolute maximum Ii/o is rated to 40mA, but personally, I would not draw more than 20mA ... If more current needed, I would use a MOSFET to drive such thing like relays.

    If you use 2 power supplys, this is a very dangerous way to destroy them.

    I got the same issue when I tried serial-debug on Rock64, output on TX is Ok, but no RX. Probably something in DT.

    Did you use either internal PullUp or external PullUp to 3.3V ? If not, the wire is acting as an antenna with random states.

    I've sacrificed a Micro cable and discovered that the ID pin is not wired ! :-( I'll have to wait the real adaptor purchased on eBay ...

    I'm still working on it, it is more difficult than expected, because it shares sunxi-common-regulators.dtsi between H3-H5 and A20 and others. My current version is enabling the PL2, but I can't make "/delete-node/" working to remove PB9, and the dmesg error still present. I also need to verify if USB0 is actually powered, but unfortunately my OTG adaptor is a Mini-USB not Micro-USB, I will need to sacrifice a Micro cable and solder a female connector on it...

    Yes, it is working well since months using the overlay.

    @zador.blood.stained, I don't understand your reply. We are talking about OPi0 here, right ? My OPi0s with Mainline don't load any PCF8591 driver, and i2cdetect doesn't show this 0x48 ...
  9. martinayotte
    Why it is required to add that in blacklist if there is no PCF8591 present on OPi0 ? And if it is actually present on I2C bus, it should appear as 48 instead of UU after blacklisting it.

    After having booted Armbian from SD, you can use nand_sata_install.sh to copy the Armbian over the current Android image present in the eMMC. Then, shutdown, remove the SD, and re-power the board, it will boot Armbian from eMMC.

    They should add some "apt-mark hold <packages>" into their images, that would prevent bad upgrades ...

    It seems that you took the image from there : https://archive.outernet.is/images/Dreamcatcher Armbian/ They probably didn't do their own testing properly according to the log you've provided : "File not found"

    Do you have any USB-Serial dongle connected to debug ?

    Excuse-me my ignorance, but where can I switch theme ?

    Yes, you can disable peripherals in an overlay by changing their status to "disabled". But you won't be able to change SPI pins ...

    Good catch ! It was there when we were under 4.10 ! I will prepare a patch ...

    There is no real PMIC on OPiZero, this means the power supply still plugged on the SoC, even after shutdown command.
  20. martinayotte
    You're lucky that you didn't destroyed those GPIOs ... You're better use some MOSFET or other circuit to drive this relay board.

    The way you are reading the serial port is ugly since you try to read(1000) without even checking if there is something to read, and yes 0.1ms is waste of time, especially if serial is empty, you should make it longer. You should is serial.inWaiting() > 0 to check if at least one char has come in...

    Do you have any USB Serial to connect and capture log during your Mainline boot ?
  23. martinayotte
    Their isn't much diffs bewtween H2+ and H3. But as I stated above "If your wish is to have a LED reflecting the fact that the chip is been resetted but no single byte read from SDCard, your only solution is to connect that LED to reset, but that doesn't mean much since a reboot won't make that LED turned on." , I don't think your wishes can be achieve ...

    Personally, I don't feel that Armbian PC2 development is stalled ! If you have any enhancement to provide to Armbian, please, submit a PR !

    Although I didn't raad the whole thread and links, why are you trying to do ssh on port 2222 while standard port is 22 ?
