Hello, here: http://ftp.enneenne.com/pub/misc/au1100-patches/linux/patch-au1x00-serial-phys-addr a little patch (against «linux-2.6.16-stable» branch and tested on au1100 based board) to fix the addresses specification for the serial driver. With this patch at boot time we get: Serial: 8250/16550 driver $Revision: 1.90 $ 3 ports, IRQ sharing disabled serial8250.7: ttyS0 at MMIO 0x11100000 (irq = 0) is a 16550A serial8250.7: ttyS1 at MMIO 0x11200000 (irq = 1) is a 16550A serial8250.7: ttyS2 at MMIO 0x11400000 (irq = 3) is a 16550A and into procfs we read: wwpc:~# cat /proc/iomem 10100000-10200000 : au1xxx-ohci.0 10500000-1050ffff : eth-base 10520000-10520003 : eth-mac 11100000-1110001f : serial 11200000-1120001f : serial 11400000-1140001f : serial wwpc:~# cat /proc/tty/driver/serial serinfo:1.0 driver revision: 0: uart:16550A port:11100000 irq:0 tx:3905 rx:39 RTS|CTS|DTR|DSR|CD|RI 1: uart:16550A port:11200000 irq:1 tx:0 rx:0 CTS|DSR|CD|RI 2: uart:16550A port:11400000 irq:3 tx:0 rx:0 CTS|DSR|CD|RI Ciao, Rodolfo -- GNU/Linux Solutions e-mail: giometti@xxxxxxxxxxxx Linux Device Driver giometti@xxxxxxxxx Embedded Systems giometti@xxxxxxxx UNIX programming phone: +39 349 2432127
