Re: Luckfox Pico Mini B - can't open i2c-3 port from luckfox-config

Simulating an I2C slave device is not a common application scenario for Linux SoC. The hardware I2C controller driver of Luckfox Pico Mini B does not contain any content related to simulating a slave device. The TRM also does not specify the relevant registers.
Therefore, the recommended approach is to sacrifice the speed and use GPIO to simulate I2C. You need to operate it by combining the relevant driver source code yourself.
