One question about gpio i2c : i have various 0,91   SSD1306 oled displays that i use in arduino.  ...

I have testet I2C with an RTC at address 0x68.

  • i2c-0     works fine
  • i2c-1    does not work
  • i2c-2     works fine
Here the screenshots from Bus 0:
  1. i2cdetect -r 0 0x03 0x77

Hi friends:
   
    I have do some test to use I2C0, I2C1 and I2C2. As you see,
    As default, I2C0 and I2C2 has opened, it has work well.

    But, If you want to use I2C1, you should do some configure on uboot,
    Now, I'm not update newest uboot source code into offical github.
    I have configure I2C1 on uboot and it work well, I will update uboot souce code
