  1. Hi, I try to connect a tft 240x240 display via SPI with my BPI m2zero and i am looking for a suitable library written in C. The display uses ST7789 driver and it will be used in combination with thermal camera. I've tried to use producers library for RPi https://www.waveshare.com/wiki/1.54inch_LCD_Module but the screen only blinks when i run a program with test bitmap. I tested it on Arduino and the display works fine. If someone was able to run such a display, can you share your library? Thanks for all the help
  2. I'm using Banana Pi M2 Zero with Armbian Debian GNU/Linux 10 (Buster). Compiled the image myself with the latest source code using the armbin/build repository. I want to be able to do serial communication on pins 8 and 10. I'm looking for something to appear at /dev/ttyAMA0, so I can communicate with it. I saw some other forum posts which mentioned it'll happen on /dev/ttyS0 , however even that is not happening. The serial communication is working via FTDI (using the USB side connected to the Banana Pi), which indicates there is no problem with the other device. This is what the configuration looks like using "sudo minicom -s". +-----------------------------------------------------------------------+ | A - Serial Device : /dev/ttyS0 | | B - Lockfile Location : /var/lock | | C - Callin Program : | | D - Callout Program : | | E - Bps/Par/Bits : 115200 8N1 | | F - Hardware Flow Control : No | | G - Software Flow Control : No | | | | Change which setting? | +-----------------------------------------------------------------------+ | Screen and keyboard | | Save setup as dfl | | Save setup as.. | | Exit | | Exit from Minicom | +--------------------------+ I have enabled "uart1" using "sudo armbian-config -u" -> System -> Hardware. Connecting Rx, Tx on the pins 8 and 10 also does not show up in "dmesg" How do I go about debugging the issue or finding the root cause of the problem? Many thanks!
  3. Hi, I am stuck integrating IR in my board banana pi m2 zero. Can anyone guide me to setup IR?
  4. Hi, so without knowing what the swappiness actually is I changed the value from 100 to 512. Since then, I can't boot my Banana Pi M2 Zero. Shortly after that, I remembered again: swappiness is the percentage of how often to use swap and not the maximum amount of storage. Can I repair it inside uboot? Can I plug the sd card into my PC and edit the files there? Here is the log from the serial console. It's stuck forever after the last line. ..............................................................

  5. I got myself a Banana Pi M2 Zero (with H3 chip) and am running Armbian (Armbian_21.08.1_Bananapim2zero_buster_current_5.10.60) on it. I have enabled SPI by adding the spi-spidev dt overlay. Now I want to use both CS pins at the same time so that I can connect two devices. The spi-add-cs1 overlay doesn't change anything so I researched a bit and found this custom overlay. Unfortunately it didn't work too and there is still only a single spidev available. Is there any way to enable both of them at the same time?
  6.

  7. Upgrading to the latest Armbian build 5.15.25 on the M2-Zero has caused the camera to stop working. I had a build from https://github.com/Qengineering/BananaPi-M2-Zero-OV5640, and ive seen my camera work with Gstreamer but i now need it to use the hardware encoding. So i used https://wvthoog.nl/nanopi-ov5640-camera/ to enable the Cedrus encoder, but upgrading the devices loses the camera and /video1. There is no /video1, or media1. Ive tried to edit the dts files, build and push them but no luck. Any advice here would be good. I know there are a few topics on here on this subject, but they are all slightly different issues because of the kernel used.

  9. I am trying to configure my Banana Pi M2 Zero to use UART to communicate with my 3D Printer. I used Armbian config to setup UART 3 (Pins 8 & 10). I can't seem to communicate over the port. How do I test and do I need to make other config changes? Thank you!
  10. Hi All, I''m using a BPI M2 Zero, where a 100 MBit ethernet Interface is implemented on the board. Since I'm using DHCP for this interface, I found that the MAC Address of this eth0 interface changes on every boot. The MAC Address of the wlan0 interface is permanent and don't changes during boots. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Di 30.

  11. Hey, I am using the Image from the Armbian Download site: Armbian_20.11.6_Bananapim2zero_bullseye_current_5.10.4 and I am trying to get SPI to work, enabled it using armbian-config and through editing the /boot/armbianEnv.txt verbosity=1 bootlogo=false console=both disp_mode=1920x1080p60 overlay_prefix=sun8i-h3 rootdev=UUID=034edbda-9395-4820-87a1-f3a83bad8a58 rootfstype=ext4 overlays=spi-spidev usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u But after a reboot it does not show in /dev/ (what seems odd, i2c-0 shows in /dev/ even though it is not enabled in the armbianEnv.txt) As far as I understand it, the dts for h3 should be the same for h2+ ? I also found a file called "sun8i-h2-plus-bananapi-m2-zero.dtb" under /boot/dtb after some research I found out that this is a device tree binary (thats also why I cant read it) but I couldn't find any information on how to use it. Or how I could replace the spi-spidev.dtd with this h2 one. I also already tried the focal_current_5.10.4 Image same result. Thanks in advance Lukas
  12. Greetings, Some time ago, I built armbian with kernel 5.4.51. I applied a patch to two dts files that allowed for the OV5640 camera to work. By "work", I mean /dev/video0 was present in the system and /dev/media0 was also present. I could set camera parameters with media-ctl pointing to /dev/media0. Now, I've updated, and using a legacy kernel, 5.4.65, I cannot reproduce this. I've applied the same dts changes, but upon booting this image /dev/media0 is missing. I've compared the two kernel configurations, and there are very minimal differences: # diff config-5.4.51-sunxi /boot/config-5.4.65-sunxi 3c3 < # Linux/arm 5.4.51 Kernel Configuration --- > # Linux/arm 5.4.65 Kernel Configuration 2116d2115 < # CONFIG_BLK_DEV_SR_VENDOR is not set 2644a2644 > # CONFIG_RTL8192EU is not set 3165a3166 > CONFIG_SPI_DYNAMIC=y likewise, comparing loaded modules shows me that on my 5.4.65 build ov5640 is not in use: Module Size Used by ov5640 28672 0 On my 5.4.51 build, it is in use. I'm not sure where to go from here.

  14. Hello, I have a GPIO pin that is high when starting the board. I am trying to force it low.

Thanks!
  15. Greetings, I've been building an image for a banana pi m2-zero. I noticed during the build that the following DTS is chosen: sun8i-h3-orangepi-zero-plus2.dt There is a sun8i-h2-plus-bananapi-m2-zero.dts in the same directory, that I think would be more relevant. How can I choose this DTS instead?
  16. Ok, so, first of all, I am a complete noob. I bought Banana Pi thinking that it is similar to Raspberry Pi's architecture but it's obviously not. I bought a 240x240 Waveshare 1.3 inch hat and I was wondering how to get it working on my Banana Pi Zero (H2+). On Raspberry Pi I can use Juj's fbcp-ili9341 driver but it's probably not compatible with Armbian, right? How do I go about it? Also, it would be nice to know how to detect buttons (that are on the hat) and convert them to key strokes. Thanks!
  17. hello dear all on banana pi - i have connected all the wires but: no signal on screen what can i do now - plz advice update: found an very very interesting thread: see https://www.raspberrypi.org/forums/viewtopic.php?t=34061 presume, you have installed your selected OS on SD card. Boot sector of the SD card is normally accessible from Windows, so you can edit file config.txt. What you maybe need? Add into config.txt this line: Code: Select all hdmi_force_hotplug=1 well - this can be a good hint.. what do you say - btw. How to edit this line!? btw found some additonal texts: https://raspberrypi.stackexchange.com/questions/2169/how-do-i-force-the-raspberry-pi-to-turn-on-hdmi Add these two lines to /boot/config.txt and reboot Raspbmc: hdmi_force_hotplug=1 hdmi_drive=2 hdmi_force_hotplug=1 sets the Raspbmc to use HDMI mode even if no HDMI monitor is detected. hdmi_drive=2 sets the Raspbmc to normal HDMI mode (Sound will be sent if supported and enabled). Without this line, the Raspbmc would switch to DVI (with no audio) mode by default. config.txt is read by the GPU so it will work on every distro. There's two ways to do it. In older Pi installs, use the fb0 framebuffer when you want to display stuff on the HDMI/TV display, for example: FRAMEBUFFER=/dev/fb0 startx will use the HDMI/TV framebuffer for X windows instead of the PiTFT On Jessie Pi installs, run sudo nano /usr/share/X11/xorg.conf.d/99-fbdev.conf to edit the configuration file and make sure it contains: Copy Code Section "Device" Identifier "display" Driver "fbdev" Option "fbdev" "/dev/fb0" EndSection change the Option "fbdev" "/dev/fb0" line to Option "fbdev" "/dev/fb1" if you want the xdisplay on the PiTFT or fb1 to fb0 for HDMI output. Update: If don't see the code above in the file, then simply copy and paste what is shown in this answer at the bottom of that file. If you can't find 99-fbdev.conf file in that folder, then there is probably another file with different name like 10-evdev.conf in the same folder which you will have to modify to make it work as described above.
  18. Hi all, I just downloaded the Armbian(5.36 xenial-next)-based image for BPI M2 Zero, that comes with kernel 4.14.3-sunxi. I'm looking for kernel headers for this kernel, but I can't find it in armbian's repo. Could you help me to retrive them? Thank you!
