Hi!
I have installed Armbian buster 21.08.3 and can`t discover any externally connected i2c devices, such as rtc or ssd1306
Any ideas?
i2cdetect -l
i2c-2   i2c             rk3x-i2c                                I2C adapter
i2c-0   i2c             rk3x-i2c                                I2C adapter
i2c-5   i2c             rk3x-i2c                                I2C adapter

sudo i2cdetect -y 0                                                                            
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Your issue report is not a valid bug report per the Armbian bug reporting instructions (https://www.armbian.com/bugs).  With limited resources the Armbian project is only able to spend time on issues where all the requested information has been provided and for only the boards/images/software that are supported.  Your report is invalid for one or more of the following reasons (non-exhaustive list):

 

  • it is for an unsupported board or image (CSC/EOS/WIP/edge)
  • it is for software that is not supported (such as userspace modules installed on top of the core operating system)
  • it has been logged in the wrong forum (for example requests for help that are not actual bug reports)
  • it lacks requested data (armbianmonitor output)
  • it could have been easily solved by a quick search and/or reading documentation

 

Please review what you have submitted and the bug logging instructions (https://www.armbian.com/bugs) and either add the required information or open a new topic in the correct forum (such as P2P Help or Off-Topic)
