FYI: Armbian 24.5.1 re-enabled GPIOFS, so the possiblitiy of using well known method of playing with gpio pins (/sys/class/gpio/) is back and there's no reason to use miserable gpiod toolset

I know about official Debian and that it can be installed on eMMC but it has the same "issue" as official OpenMediaVault - I can't find a way to enable I2C because /boot folder is almost empty and there's no dtb files and no config.txt-like file to enable overlays. On Arbian it's all there...

I am on openmediavault and did not find a way to get i2c-8 to work ;( That's the issue I had with official openmediavault image. So I decided to switch to Armbian and finally made it working. Also on Armbian (which is based on Debian 12) you can install newer version of openmediavault. But... I hav...

If anyone is interested, I wrote a simple Python-based systemd service to make use of the OLED screen and User button.

Answering myself. Yes, there is a quite nice method. There's an event associated with this button. /dev/input/by-path/platform-gpio-keys-event points to an event (number 5 in my case). This is the script (Python3): import struct with open(f'/dev/input/by-path/platform-gpio-keys-event', "rb"...

Thanks. 1. I believe you forgot to add 5 to the final result, so the pin is 29. 2. I'm using Armbian and there's no /sys/class/gpio directory (no sysfs for gpio), so the only way to access gpio is to use gpiod tool. It's miserable, I know :( Long story short - I've found a way to read the status of ...

Ok, found it here: https://wiki.friendlyelec.com/wiki/images/1/15/CM3588_NAS_SDK_2309_SCH.PDF, page 16.

Does anyone know how to access user button programatically?
According to the doc it should be connected to GPIO0 D5 but I cannot see any change in returned data from when the button is pressed and when it's not.

This is mine

Hi. I'm using official OpenMediaVault software with NAS kit which has been installed on eMMC. According to the doc (wiki page) there is one I2C located on GPIO header. In the CM3588 NAS SDK Schematic pdf I've found that SDA=Pin3 and SCL=Pin5. I'd like to use it for OLED screen. I do have some experi...

Hi.
I cannot find anything about GPIO pins (40) of CM3588 NAS Kit.
Has this been published somewhere yet?
