We are working on P1021.We would like to use few pins of Elbc as QUICC Engine  pins. Those are  as listed below

LA31        as    RXD0

LWE-B1    as TDMC (TXD1)


Here Elbc is connected to the Flash and it is in 16bit mode.So LA31 is not connected to flash..


I am using flash at power on time for copying the uboot and os to the DDR. After words  i am not using flash.

here  i want to operate P1021 as Elbc mode at power on  and later i want to configure as QUICC Engine mode.

Here i would like to know that is it possible to configure the Elbc pins as quicc engine pins at run time.
