Hi,

In LS1043A, We wanted to use EMI1_MDC/GPIO3_00/EMI1_MDIO/GPIO3_01 Pins as Ethernet Management Interface and EMI2_MDC/GPIO4_00 / EMI2_MDIO/GPIO4_01 as GPIO.

Kindly confirm shall we configure the Ethernet Management interface (EMI2) as GPIO and EMI1 as Ethernet Management Interface?

Thanks.

Yes, your understanding is correct, you should configure EM1 to "0" and EM2 to "1" in RCW.


Have a great day,

But in Code Warrior we are not able to select Between GPIO and EMC.

In Code warrior for RCW bit(425-426) what Value should i keep in order to use EM1 and GPIO(EM2 pins). It is coming as option such that i can either choose as EM or GPIO for both EM1 and EM2. Please confirm RCW Value need to be set for our requirement.

I do not see this issue in my installation of CodeWarrior. Please update your CodeWarrior to most recent version.
