Hello.

I'm using LTIB in LPC3250 Developer's Kit and has enable:
    UART #1 - ttyTX0
    UART #2 - ttyTX1
    UART #3 - ttyS0
    UART #4 - ttyS1
    UART #5 - ttyS2

I suppose it is this distribution.
But do not work with "minicom" on DB9 connector.

So, how to use UART on linux 2.6.27.8 (LTIB) in LPC3250?

Follow the output of command "dmesg"

address@hidden /]# dmesg
Linux version 2.6.27.8
...
Serial: 8250/16550 driver4 ports, IRQ sharing disabled
serial8250.0: ttyS0 at MMIO 0x40090000 (irq = 9) is a 16550A
console [ttyS0] enabled
serial8250.0: ttyS1 at MMIO 0x40080000 (irq = 7) is a 16550A
serial8250.0: ttyS2 at MMIO 0x40088000 (irq = 8) is a 16550A
lpc32xx_hsuart.0: ttyTX0 at MMIO 0x40014000 (irq = 26) is a lpc32xx_hsuart
lpc32xx_hsuart.0: ttyTX1 at MMIO 0x40018000 (irq = 25) is a lpc32xx_hsuart


Regards.
