Hi I want to enable I2C in U-Boot to send boot messages to an Oled, which will later used to select the Linux of my Dualboot.
So after I enabled the I2C and see boot messages, I will try to get Dual Boot working.

I tried:
CONFIG_CMD_I2C=y
CONFIG_SYS_I2C=y
CONFIG_I2C0_ENABLE=y
CONFIG_SYS_I2C_SOFT=y
CONFIG_SOFT_I2C=y
CONFIG_SYS_I2C_BUS=0
CONFIG_SYS_I2C_SLAVE 0

and this:
CONFIG_VIDEO_LCD_PANEL_I2C=y
CONFIG_VIDEO_LCD_PANEL_I2C_SDA=PA12
CONFIG_VIDEO_LCD_PANEL_I2C_SCL=PA11

but only in the first I can see the i2c bus via the U-Boot promt, but cant access it
