You can create device nodes on the rootfs without anything being bound to them. One of the easiest ways to see if something discovered the serial port is to look in the boot output. You should see something like: serial8250.0: ttyS0 at MMIO 0x1ef600300 (irq = 17) is a 16550A console [ttyS0] enabled, bootconsole disabled console [ttyS0] enabled, bootconsole disabled serial8250.0: ttyS1 at MMIO 0x1ef600400 (irq = 18) is a 16550A serial8250.0: ttyS2 at MMIO 0x1ef600500 (irq = 19) is a 16550A serial8250.0: ttyS3 at MMIO 0x1ef600600 (irq = 20) is a 16550A or: 1ef600300.serial: ttyS0 at MMIO 0x1ef600300 (irq = 17) is a 16550 1ef600400.serial: ttyS1 at MMIO 0x1ef600400 (irq = 18) is a 16550 1ef600500.serial: ttyS2 at MMIO 0x1ef600500 (irq = 19) is a 16550 1ef600600.serial: ttyS3 at MMIO 0x1ef600600 (irq = 20) is a 16550 >BTW where can I see the board's DTS file? arch/powerpc/boot/dts/sequoia.dts josh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
