Using busybox and extlinux to build a Linux system (below) on the computer compactflash (CF card)

<Industrial Computer (AMD lx processor platform, non-arm) Linux Kernel & busybox compilation option configuration>

 

(1) configure and compile busybox:

 

Note: the target machine of this compilation is not an arm board, but an industrial computer (Yanhua 3355). The CPU is amd low power lx800/500 MHz and lx600/366 MHz processor,

So ~, Note that it is different from traditional arm platform transplantation ~

Modify makefile,
Changed row 164 to cross_compile? = NULL
Change row 189 to arch? = I386
# For the ARM platform, cross_compile? = Arm-Linux-, Arch? = Arm,

The default settings are used for the moment. If you do not modify the makefile, runMake menuconfigTo enter the configuration page,

 

General configuration --->
[*] Show verbose applet usage messages
[*] Store applet usage messages in compressed form
[*] Support-install [-S] to install applet links at runtime
[*] Enable locale support (system needs locale for this to work)
[*] Support for-long-Options
[*] Use the devpts filesystem for unix98 ptys
[*] Support writing pidfiles
[*] Runtime SUID/SGID configuration via/etc/busybox. config
[*] Suppress warning message If/etc/busybox. conf is not readable
 
Build options --->
[*] Build busybox as a static binary (no shared libs)
[*] Build with large file support (for accessing files> 2 GB)
 
Installation Options->
[] Don't use/usr
Applets links (as soft-links) --->
(./_ Install) busybox installation prefix

 

Busybox library tuning --->
(6) Minimum Password legth
(2) MD5: Trade bytes for speed
[*] Fsater/proc scanning code (+ 100 bytes)
[*] Command line editing
(1024) Maximum length of input
[*] Vi-style line editing commands
(15) History Size
[*] History saving
[*] Tab completion
[*] Fancy shell prompts
(4) Copy buffer size, in kilobytes
[*] Use IOCTL names rather than hex values in error mess
[*] Support InfiniBand HW
 
(2) LINUX module utilities --->
(/Lib/modules) default directory containing modules
(Modules. Dep) default name of modules. Dep
[] Simplified modutils
[*] Insmod
[*] Rmmod
[*] Lsmod
[*] Modprobe
----- Options common to multiple modutils
[] Support Version 2.2/2.4 linux kernels
[*] Support tainted module checking with new kernels
[*] Support for module. aliases file
[*] Support for modules. symbols file

 

Exit the make menuconfig interface and execute:
Make
Make install

Generate the busybox/_ Install Folder;

 

 

(2) configure and compile the kernel:

 

Decompress the kernel source code:Tar xvzf linux-2.6.32.2.tar.gz
Modify makefile:VI makefile
Enter/in VI to enter the search, enter cross_compile, and find
Export kbuild_buildhost: =$ (subarch)
Arch? = $ (Subarch)
Cross_compile? =

To:
Export kbuild_buildhost: =$ (subarch)
Arch? = X86
Cross_compile? =

If the target machine is an ARM platform and the compiler prefix is arm-Linux-, then:
 Export kbuild_buildhost: =$ (subarch)
Arch? = Arm
Cross_compile? = Arm-Linux-

Then executeMake menuconfig
