On the Pi 4, the GPIO pins 22 and 23 map to i2c6 (ref). However, on Pi 5: The i2c6 maps to MIPI CAM/DISP0 using sda=38,scl=39. The i2c4 maps to MIPI CAM/DISP1 using sda=40,scl=41. So if someone tries to use a MIPI camera, it will conflict: BlueOS/install/boards/bcm_2712.sh Line 58 in bfbe43a "dtoverlay=i2c-gpio,i2c_gpio_sda=22,i2c_gpio_scl=23,bus=6,i2c_gpio_delay_us=0" \ ..and i2c4 is symlinked to i2c3: BlueOS/core/tools/blueos_startup_update/blueos_startup_update.py Lines 277 to 287 in bfbe43a def update_i2c4_symlink() -> bool: logger.info("Running i2c4 symlink update..") i2c4_symlink = "/dev/i2c-4" i2c4_device = "/dev/i2c-3"
