2410linux can finally use the File System

2410linux can finally use the File System-Linux Enterprise Application-Linux server application information. See the following for details. Original Author: sensen

Unconsciously bought a realarm-2410 Development Board almost a month, WinCE4.2 can be used, but Linux2.42 has been running can't, the more worried the more can't use. But I never gave up, so I don't know how many roads I 've taken.

In this case, the computer serial port is burned out. I went to Zhujiang Road to buy a pci-to-Dual-serial port card, but there was a driver in Windows, but I didn't know how to use it in the LIniux operating system, after several days of getting started on the internet, I can finally use PCI to switch to the serial port in the Liunx operating system. The steps for installing the driver and the displayed content are as follows:

Note the following when enabling nfs:

Here is the original command:

# Root from nfs
Param set linux_cmd_line "console = ttyS0 root =/dev/nfs nfsroot = 192.168.253.1:/real2410/root_nfs ip = 192.168.253.8: 192.168.253.1: 192.168.253.1: 255.255.255.0: www.realembed.com: eth0: off"

Because I use the serial port converted from pci to ttyS2, I changed console = ttyS0 to console = ttyS2.

Param set linux_cmd_line "console = ttyS2 root =/dev/nfs nfsroot = 192.168.253.1:/real2410/root_nfs ip = 192.168.253.8: 192.168.253.1: 192.168.253.1: 255.255.255.0: www.realembed.com: eth0: off"

The result remains incorrect. This evening, we found that console = ttyS0 indicates the serial port of the Development Board. The operation is still incorrect. The prompt message in minicom should be "Incorrect root configuration", so I will add the following statement in the original etc/exports according to the instructions:

/Real2410/root_nfs * (rw, sync, no_root_squash)

Change

/Usr/local/arm/real2410/root_nfs * (rw, sync, no_root_squash)

At the same time, the vivi parameter command is also changed to the following full directory:

# Root from nfs
Param set linux_cmd_line "console = ttyS0 root =/dev/nfs nfsroot = 192.168.1.17:/usr/local/arm/real2410/root_nfs ip = 192.168.1.100: 192.168.1.17: 192.168.1.17: 255.255.255.0: www.realembed.com: eth0: off"

# Root from mtd
Param set linux_cmd_line "noinitrd root =/dev/mtdblock/2 init =/linuxrc console = ttyS0"


/Home/pengsen/rootnfs * (rw, sync)
/Usr/local/arm/real2410/root_nfs shi * (rw, sync, no_root_squash)

After this modification, you can run 2410 to run linux.
