2410linux终于可以使用文件系统了
原创作者：森森
不知不觉中买了realarm-2410开发板差不多有一个月了，好不容易WinCE4.2可以使用了，可是Linux2.42一直运行不了，越是着急越是用不了。可我一直都没有放弃，为此，不知道走了多少冤枉路。 为这，还把电脑串口给烧坏了。害了我又到珠江路去买了一个pci转双串口卡，可在Windows倒是有驱动，在LIniux操作系统却不知道怎么使用，不知道怎么搞驱动啊，好不容易泡在网上好几天才搞明白了，终于可以在Liunx操作系统中用PCI转串口了。下面是安装驱动的步骤及显示的内容： [root@localhost root]# setserial /dev/ttyS0 -a /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 500, divisor: 0 closing_wait: 30000 Flags: spd_normal skip_test auto_irq [root@localhost root]# setserial /dev/ttyS1 -a /dev/ttyS1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3 Baud_base: 115200, close_delay: 500, divisor: 0 closing_wait: 30000 Flags: spd_normal skip_test auto_irq [root@localhost root]# setserial /dev/ttyS2 -a /dev/ttyS2, Line 2, UART: unknown, Port: 0x03e8, IRQ: 4 Baud_base: 115200, close_delay: 500, divisor: 0 closing_wait: 30000 Flags: spd_normal skip_test auto_irq [root@localhost root]# more /proc/pci PCI devices found: Bus 0, device 0, function 0: Class 0600: PCI device 8086:2560 (rev 3).
