When I include dtparam=i2c_vc=on to the config.txt file I get access to the I2C-O bus, as expected. However , in addition to /dev/i2c-0 appearing, I also get /dev/i2c-10 and /dev/i2c-11 , and when attempting to provision GPIO-11 in Pi4J, I no longer have access to GPIO-11 (BCM pin 7). Web3 apr 2024 · Do NOT use in conjunction with dtparam=i2c_vc=on. From the 5.4 kernel: onwards the base DT includes the use of i2c_mux_pinctrl to expose two: muxings of BSC0 - GPIOs 0&1, and whichever combination is used for the: camera and display connectors. This overlay disables that mux and: configures /dev/i2c0 to point at whichever set of pins … bownow サポート
