How to enable Second UART in MPC8323E-RDB board.?

Hello,

Can anyone suggest how to enable the Second UART in MPC8323E-RDB board.? Is there any possibility in enabling UART while configuring Kernel using LTIB.?

Please suggest relevant document available, if any.

I am using LTIB to build Kernel and rootFs images. Please respond as soon as possible.

Thanks and Regards,

The MPC8323 DUART is enabled in the MPC832x_rdb LTIB Linux BSP. Attached file contains .dts file from this BSP. This file is available using the following path:

ltib-mpc832x_rdb-20081112/rpm/BUILD/linux-2.6.20/arch/powerpc/boot/dts

Find definition for serial0 and serial 1 in this file.

This file shows that both UARTs are enabled in this BSP.

Have a great day,
Pavel Chubakov
