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: -- -- -- -- -- -- -- -- .................................. You can also enter the appropriate values yourself in the file: sudo nano /boot/armbianEnv.txt 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=sm1-odroid-c4-i2c0 sm1-odroid-c4-i2c1 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u regards

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. Namely, the system lacks 4 working processor cores 🙂 ... only one. Something is wrong at startup because the green LED is on and the red LED is constantly flashing/pulsing.

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?
