Banana Pi BPI-M4 Zero H618 SBC GPIO fcuntion
I have this same OLED screen. Need to test.
The source code did not work for me, it compiles fine but I get “unknown model” error. So I modified this to work with the M4 Zero exclusively.

which image you got “unknown model” error?
M4 Zero 4G/32G model. The first repo gives the error. The second repo is just a copy that forces M4 Zero. It won’t work with other boards.
i mean which bananapi bpi-m4z image flashed that got the “unknown model” error with first Wiringpi repo.
Which M4 Zero do you have?
are there different variants for sale？
3 as far as I can tell. Mine is the middle one, it’s marked as a v2.0 with 2432 on the back which I assume is a revision number. The one in the video above looks like the one marked as v00 with 2343 on the back.
The repo variant I posted forces it into M4 Zero regardless of the actual board. I called this debug function directly and got nothing but blanks, so I removed the references to all other boards.
Anyway, I hope it helps someone. I have to keep pushing forward.
as i know, armbian official kernel 6.6 m4zero images are not support network, wifi or ethernet for your “2432” board, please execute the following command and provide the output
$ cat /proc/device-tree/model
$ cat /proc/cpuinfo
$ cat /proc/version
I also use 2432, this is the production date
the image is 20241011_Bananapi-Armbian_24.8.2_Bpi-m4berry_jammy_legacy_5.4.125_minimal.zip,
using GitHub - Dangku/WiringPi: WiringPi for Bananapi M5/M2pro/M2S/CM4/M4B/M4Z/F3
and it works fine
And how did you get the OLED to display like the video? Here is my output after compiling and running the OLED example.
I appreciate you guys trying to help me figure out why it wasn’t working for me, but I only have until the end of the week to finish the evaluation, so I already moved ahead with my own mod, which works on all 8 images I have tried regardless of kernel or networking abilities.
The OLED sample also did not work for me, it only shows the date in the command line output. So I wrote a new one which works on both the 128x32 and 128x64 OLED i2C modules I have. This is enough for me to finish my evaluation.
