Gemini info 😞 ..... In the official, pure Armbian for Banana Pi M2 Pro, enabling SPI is currently extremely difficult (and even impossible for the average user) If you absolutely need the SPI bus for your project: Operating system change: SPI works without any problems on official system images provided directly by the board manufacturer (BPI-M2 Pro Debian/Ubuntu with kernel 4.9 from Amlogic). The manufacturer uses an older but fully modified kernel (Kernel BSP), where all pins are rigidly and correctly assigned. Or... Staying with Armbian: If you must stick with Armbian, it's safer to abandon SPI attempts and—if possible—connect the target device to a free I2C bus or UART serial communication (which work flawlessly in Armbian on this board). But ultimately, the Armbian system developer will have to decide. (Maybe there is some method to enable SPI on the latest Armbian images/firmware?) 🙂 Check https://docs.banana-pi.org/en/BPI-M2_Pro/BananaPi_BPI-M2_Pro Armbian older firmware (bananapi manufacturer's firmware) (bookworm): https://drive.google.com/drive/folders/1DPkc7AHEZVS7PT_yzhNH1Dfuiz99mE0p

I tried to enable the I2S / PCM5102 service with AI, but unfortunately, despite numerous attempts, I couldn't. But anyone can use a USB audio card. Maybe someone else will figure out how to enable it 🙂 Best regards

Thank you for any information... when I have more time I will try with the help of AI... because I don't have enough knowledge myself 🙂 regards

Is it possible to enable the I2S service (for audio) on BananaPim2pro? In the program configuration: armbian-config / manage device tree overlays...there are no entries for: I2S. Maybe someone already knows what to enter or how to enable it 🙂

Thanks for the info to try other options 🙂 Thanks for the tip, I'll try other options 🙂 It worked for: odroid-c4 ... basically, the settings are the same as for the OrangePI3LTS, I'm talking about connecting cables to a 40x2 / 20x2 LCD. The diagram for the BananapiM2pro is as follows: My Winstar 40x2 OLED LCD compatible with drivers: hd44780 / driver: WS0010 is detected in the system as: 3f .................................. sudo i2cdetect -y 0 [sudo] kris: 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3f 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- ..................................

What should the correctly enabled I2C service (for a 40x2 LCD) look like on Bananapim2pro? Should I edit the armbianEnv.txt file and add, for example, the following entry: overlays=i2c0 i2c1? The armbian-config service is a bit confusing, and after editing it, I get this: ........................ verbosity=1 console=both overlay_prefix=meson fdtfile=amlogic/meson-sm1-bananapi-m2-pro.dtb rootdev=UUID=a4fb8074-c453-45da-ab31-4d61dca46cfa rootfstype=ext4 overlays=i2cA i2cB usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u .................. There are other options, but they probably don't apply to bananapim2pro. : sm1-odroid-c4-i2c0 g12b-bananapi-cm4-i2c2 g12a-radxa-zero-i2c-ao....

After the update/upgrade, all CPUs are now installed nproc 4 This didn't fix my Bluetooth (maybe it's some individual bug in my system?) but since Bluetooth works correctly in the new images for OrangePi 3 LTS, I'm marking this thread as resolved... I'll probably install the latest image soon, although it will be time-consuming. ........................... orangepi3-lts:~# dmesg | grep "CPU" [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] [ 0.000000] Detected VIPT I-cache on CPU0 [ 0.000000] CPU features: kernel page table isolation forced ON by KASLR [ 0.000000] CPU features: detected: Kernel page table isolation (KPTI) [ 0.000000] SLUB: HWalign=64, Order=0-3, MinObjects=0, CPUs=4, Nodes=1 [ 0.000000] rcu: RCU restricting CPUs from NR_CPUS=8 to nr_cpu_ids=4.

I tested the new version (Armbian_26.2.0-trunk.591_Orangepi3-lts_forky_current_6.18.18_minimal) in terms of bloototh and it's OK... but there are errors that rule out this image.

That's strange 🙂 ...we have the same kernel. Maybe something's broken in the system? But I haven't messed with Bluetooth in the system.

Wi-Fi works → so the problem is only in GPIO / DTB initialization for Bluetooth It worked on the older kernel, but now it doesn't 😞.... Supposedly this is the cause, but is it really? armbianmonitor -u https://paste.armbian.com/uzudezufit

On my Orange Pi 3 LTS I don't use ethernet, only wifi and it works OK... maybe that's why I didn't notice the problem... but here is some information about ethernet on Pi 3 LTS https://forum.armbian.com/topic/19846-orange-pi3-lts/page/11/#comment-226536

I switched to the Armbian version of Debian Trixie and now it's OK

I gave some information ..... Hit:8 http://fi.mirror.armbian.de/beta bookworm InRelease ? 🙂 If this is a bug, meaning the repositories are in beta, then OK... but I don't know if I installed them? Or are they standard in the images/firmware installations, e.g., for the Opi3LTS version? Ps. Has support for my OrangePi3LTS model been completely abandoned? ...because now I don't have the option to install the system to the emmc memory in the :armbian-config options? / nand-sata-install / armbian-install 😞 I think the easiest way would be to switch to the Debian/Triexie version from bookworm because unfortunately bookworm has only bugs and no support for the wifi card now 🙂

This is the hint I got from AI 🙂 I changed the repositories from beta to stable and installed: sudo sed -i 's|beta.armbian.com|apt.armbian.com|g' /etc/apt/sources.list.d/armbian.list and sudo apt download armbian-bsp-cli-orangepi3-lts-current sudo dpkg --install --ignore-depends=base-files armbian-bsp-cli-orangepi3-lts-current_25.8.2_arm64.deb Now it's OK....but is this the right approach?
