  1. Last year I started a solar-sensing project with the Orange-Pi-Zero (256k), Armbian5.25, legacy kernel and made it work after a while. The Wifi funktion was rather poor and deteriorating, so I ordered a new OpiZero-Plus2-H3, same physical shape and connectors (I thought). Now the -P2 Armbian image 5.30 for the new board loaded perfectly, the Wifi function is really improved due to better hardware. The python part of the code works (still) perfectly. Only (most of) the gpio-functions of my project do not work any more with the new board attached. I use PA07, PA13 and PA14 for bit-bang gpio and a 1-wire sensor via the kernel. I modified the OPi-P2 fex file, shipped with Armbian, turning off hdmi and SPI functions the same way as before, setting min clk to 408 MHz and max clk to 1200 MHz. Powersaving seems much improved. I checked the fex file for other connections to my nodes - nothing. I loaded the kernel drivers as before. But the result is: PA13 and PA14 work as before, the PA7 input pin does not see any levels (open), the 1-wire device is not recognized, neither the old or a brand-new component. I am pretty stuck - the alternative pin PA16 cannot be activated because it is not mapped in the pyA20-H3 driver. The author duxingkei33 writes the mapping can be expanded, but I could not find enough information how to define the extra parameters. The SPI built-in interface would use PA 13,14,16 but they are not all included in the pin mapping. Q: is the 1-wire function in the new Armbian for OpiZero-P2 already a tested function? Is there something new with the gpio-connector? Is there any more information available about the pin and connectors mappings for the pyA20-H3 driver? Is there already any other I/O-experience with the new Zero-P2 board around ? After quite some hours I am running out of ideas to fix it. I added the modified/reduced fex file. orangepizeroplus2-h3.fex
  2. Hello. In my project, I want to use a linphone with support for the h264 codec. In repositories there is a version of linphone but without the specified codec. I tried to build a linphone from the source code, but failed. The matter is that the assembly of the dependent package belle-sip hangs (the assembly lasted 2 days). Tell me, does anyone have any experience in successfully building a linphone from git? Now I'm trying to build a linphone on the Orange Pi zero plus 2 H3 board.

  4. Hi, I trying to use UART 1 & UART 2 at OPi Zero 2 Plus with no success with armbian stable and ubuntu server. I test all combinations, of fex settings, turn off everything except required uarts, set uart_type = 2 and etc, and it did not connect. UART0 and UART3 works fine, but I need cts-rts lines from uart2 for hi speed (it's uart_type = 4, but I would like to start regular uart first). tested with picocom, ft232 & pl2303 I use 8 & 10 pins for uart 1 and 11&13 for uart2 as described at http://linux-sunxi.org/Orange_Pi_Zero Is it correct pins? Thanks
  5. Hi, It's been a while that I'm trying to activate the AP of the OP Zero 2+ but in vain. I already succeded activating it on the OP Light using hostapd.conf and interfaces.conf, but when I tried the exact same configuration on OP Zero 2+ the AP didn't work. I tried a lot of solutions found in the internet, but none of them seem to work. Please any help would appreciated !
  6. Did they improve the wifi on the orange pi zero plus 2, or does the wifi have the same problems as the orange pi zero?
  7. Hi, What are the boot priorities on the Orange Pi Zero 2+ H3 / H5 boards? In case of a working eMMc boot, is it possible to prohibit any boot through SD? Thanks /R
  8. Funnily with Zero Plus 2 a silent downgrade to H3 happened (I would assume that's related to Xunlong's software guy Buddy not being able to resolve voltage regulation issues with Allwinner's BSP and H5): http://www.cnx-software.com/2017/03/17/18-9-orange-pi-zero-plus-2-board-allwinner-h3-wifi-bluetooth-le-hdmi-and-8gb-emmc-flash/
  9. Hi, Does anyone has image for Orange Pi Zero 2+ H3 Ubuntu Dekstop Kernel > 4.x? Thanks.
  10. recently I installed the Ubuntu Desktop on Orange Pi Zero 2+ H3 the Orange Pi Zero 2+ H3 device has only one micro USB OTG port during the first Armbian installation this port should be in dual mode -> power of course and in my opinion the second mode should be a HID gadget (g_hid) in this case we will be able to plug the keyboard via some micro USB hub and setup the system unfortunately this doesn't work like this and right now the installation process isn't so ease now the questions begins -> is it possible? Any clue how to do this? Thx PS I was able to do the installation because I have Orange Pi Zero Expansion board which is compatible with Orange Pi Zero Plus 2 H3 (confirmed with Xunlong)
  11. I just wanted to share some instructions on how to control all GPIO pins on the OrangePi Zero Plus 2 board. These instructions are meant for newbies but it can be extremely helpful if you are new to Armbian, OPI and GPIO. At least it would have been for me. There is a total of 17 different pins to control according to the schematic below. These pins are highlighted in blue numbers that indicate what GPIO port they are available at. Use these numbers in order to know that pins to control. Look for instructions further down. First off some basics: Activate a pin by exporting it. For example. In order to activate IO-0 run: echo "352" > /sys/class/gpio/export Set the direction of the port. echo "out" > /sys/class/gpio/gpio352/direction Turn it on: echo "1" > /sys/class/gpio/gpio352/value Turn it off: echo "0" > /sys/class/gpio/gpio352/value To figure out what number to use for each pin follow the schematics above or read from the list below. I really have not figured out wether it is safe to control all pins(and not just IO-pins) for output but it seems to work when I verify with a voltmeter. These pins were identified using the official schematic for the board: http://linux-sunxi.org/File:ORANGE_PI-ZERO-PLUS2_V1_0.pdf If you are interested to learn how pins are identified based on the schematic please dig deeper into these files in the GIT repo: https://github.com/armbian/linux/blob/sun8i/drivers/pinctrl/pinctrl-sunxi.h https://github.com/armbian/linux/blob/sun8i/arch/arm/mach-sunxi/include/mach/pinctrl.h GPIO Table SDA = 12 SCL = 11 IO-GCLK = 6 IO-0 = 352 IO-2 = 353 IO-3 = 3 SPI1-MOSI = 15 SPI1-MISO = 16 SPI1-CLK = 14 TXD0 = 15 RXD0 = 16 IO-1 = 107 IO-4 = 19 IO-5 = 18 IO-6 = 2 SPI-CE0 = 13 SPI-CE1 = 110 I hope this helps someone.
  12. HI! Does anyone have experience with WiFI on Orange Pi Zero Plus 2? I tried to use image Armbian Legacy 3.4.113 for NanoPi NEO Air, (hardware is same H3, wifi AP6212) without success. No any wlanX interface. Thank you for your help!
