banana-pi-m2-zero-gpio's Issues

Build doesn't work with latest Armbian

Hola!
Let me start with saying a big Thanks for the work you've done in enabling the BPi M2Zero and making it more usable (way closer to the RPi), especially filling the gap within the RPi and BPi ways they handle GPIO.

I'm currently working on porting some projects I had working on RPiZero and RPi3B with screen hats into the BPi (due chip shortage) and, while until a week or so ago I was able to build your libraries, after all the updates released this week (117 packages) for Debian (they pushed it from 11 to 11.5), I cannot longer build your libraries. Here is the /etc/os-release of my Armbian OS:

When running the automated build script, I get that apt repositories universe, multiverse and restricted are invalid (also verified this manually in two ways:

By running sudo add-apt-repository universe, which responds with Error: 'universe' invalid
By adding 'universe multiverse restricted' at the end of each line on /etc/apt/sources.list, which makes sudo apt update to indicate those repositories don't exist.

I imagine that, with the high number of new packages, there are quite a number of things that broke up, and I was wondering if you could take a look once you have some time.

Please let me know if you need any additional information.

Thanks in advance,
Wilferik

This module can only be run on a Raspberry Pi!

Hello, I'm trying to access this image however the default password gives me access denied from SSH login at my first attempt to login to the system.

Hola TuryRx,
Gracias por todo el apoyo, el trabajo se ve genial, he tratado de ver los videos pero al parecer no estan disponibles.

Old package names?

Hi,
I just tried to install your awesome project :) I really love it.
I just found a minor issue during the quick installation. The python-dev and libsdl-dev packages don't install automaticly python should now probably be python-dev-is-python3 and libsdl-dev probably libsdl1.2-dev.

I installed python3, libsdl, unrar and pip3 manually then most of the installation worked without any problems. Maybe those were caused by my manually installations: RPi.GPIO_BP/setup.py

I am running: Ubuntu Jammy Server (from your github link ;) ) on a Banana pi zero m2

I2s mic and audio

img roxas version. Can you use i2s mic and audio like on raspi? Do I need to activate anything?

about gpio BCM ID

请问，修改armbian-config里的hardware功能选项会影响GPIO的BCM编号吗？以下是我执行的gpio readall的结果，和你的图片里的编号都不一样

May I ask if modifying the hardware function option in armbian configuration will affect the BCM and wPi number of GPIO? The following is the result of my gpio readall execution, which is different from the numbering in your image

>Errors when installing on Ubuntu

I was trying to install Banana-pi-m2-zero GPIO on Ubuntu, 2022-09-27-Armbian_22.11.0-trunk_jammy_edge_lubuntu_5.19.6-qt5-swap-bpi-p2z-10804MB but ended up with "broken" OS. I did try 4 times.
During installation as root or as user with "sudo", the following errors

Permission errors

Could someone help please

How to cancel GPIO debug monitor

hi, thank you for your library, i can say its amazing.
but i have some problem

gpio=3,value=1
gpio(3),bank(0),num(3)

how to comment this debug print?
thank you

Build recipe and differences from archived Armbian

HI!

Firstly, congrats on the great work here.

I got here because I was searching for a working OS image for my Banana PI M2 Zero and realized that Armbian ditched support for it. That's a shame and I can't find the reason behind this.

Anyway. I downloaded your latest image (based on debian bullseye) and I would like to know how you built it. What are the differences between your images and archived images (available at armbian.org). Could you please share a recipe for building those images? I'm worried about the future of M2 Zeron once there's no more official Armbian support.

Problem with SD image from download section.

Good time! The topic of this question does not apply to the author's GPIO work. However, I have not yet found a solution to this problem, so I want to know if the author of the project had a similar problem, and how it was solved.

In the image that the author provides for download with a preinstalled patch, bluetooth does not work.

Here are some details, the problem is most likely at the level of the driver, the bluetooth module:

Faced the same problem, bluetooth does not work.

Help solve the problem, this assembly is very good, everything you need except bluetooth works on it. Please help, at least throw a link to some forum to solve the problem.

Trying to run PiStorm on BPi m2 zero

SPI buffer size

Hi,
I am sorry to "spam" you like this. However I am trying to increase the SPI buffer, as it seems many before me.
I have managed to enable the spi and I2C following your advices in your repos, but I am failing to set different buffer size than 4096.

I Have tried both unload the module and load it with parameter (modprobe spidev bufsiz=8192), added "param_spidev_bufsize=20480" to armbianEnv.txt; but no help.

My armbianEnv looks like this:

verbosity=8
bootlogo=false
console=both
#disp_mode=1920x1080p60
disp_mode=1280x720p60
overlay_prefix=sun8i-h3

param_spidev_bufsize=20480

Could you help? Thanks (I would not even get this far withou your repos).

One Wire

Hi!

Can you help me to get one wire working for a WS2812 led strip? I have added overlays=w1-gpio to /boot/armbianEnv.txt, but no python libraries seem to work for it sadly.

Thank you for your help in advance!
