I would like to use LCD interface as well as Profinet interface in my design is there any possibility i can use both on single processor?

Hi,

The PRU-MII signals overlap part of the LCD data signals, so you may be able to use only an 8-bit LCD alongside with Profinet.

Hi Biser

But can I use PRU-ICSS/MII1 signal they are not multiplexed with any of the LCD pin apart from LCD_AC_BIAS_EN.

You need both PRU MII interfaces for Profinet.

Take a look at the AM437x and AM572x families.
