Hello, I am working on PPC440EPx (Sequoia) to access its UART # 1 port for data transfer, while UART # 0 is connected to remote terminal access on host. However there is no module/driver listed for UART # 1 using 'lsmod'. The kernel version is 2.6.23. How can I access the UART # 1 in user space and/or kernel space? Do I need to develop own BSP for this? please help. regards, Waseem

The driver is normally built into the kernel. If the board DTS file has both UARTs listed, and you have /dev/ttyS1 on your rootfs you should be able to use it. However, Sequoia wasn't added until 2.6.24, so I'm not really sure what kernel flavor you are using. josh
