May be you mean what values should be set to the Extended RCW PinMux Control Register for required configuration?

It is supposed that on the LS1043ardb USB2_DRVVBUS USB2_PWRFAULT should be configured when system has started. Check SW3[7] settings (default should be 1). LS1043A I2C2, I2C3, and I2C4 are not used, to simplify the circuit and save many mux/demux parts, LS1043ARDB attach all I2C devices to I2C1 port.
