Xscale-GCC-3.3.3 is installed to the / usr / local / xscale / directory, and the other cross-compilation tool chain is installed in the / usr / local / arm directory.
2. Establishment: 1) Create a package: Create a working directory Lubbock in "/", then copy the required packages to the Lubbock directory: [Root @ localhost /] # mkdir lubbock [root @ Localhost /] # ...

Here, I would like to thank Chen Yu moderator and Yin Wenchao to provide patch files and modification methods.

The following operations can be added to the .bashrc file (such as /root/.bashrc) in the .bashrc file (for example, /root/.bashrc), and save the same settings after the next login.
[Root @ localhost /] # export LUBBOCKDIR = / lubbock [root @ localhost /] # cd $ LUBBOCKDIR [root @ localhost lubbock] # export KERNELDIR = $ PWD / linux-2.6.7 [root @ localhost lubbock] # export SKYEYEDIR = $ PWD / SKYEYE [root @ localhost lubbock] # @ ot @ localhost lubbock] # @ ot @ localhost lubbock】 # @ @ @ylogindir = $ PWD / TinyLogin-1.4 3. Compile system software: 1) Compile Skyeye: Skyeye's source directory configuration and compile SkyEye: [root @ localhost /] # cd $ skyeyedir [root @ localhost skyeye] # ./configure / --target = arm-elf / --prefix = / usr / local [root @ LocalHost Skyeye] # make [root @ localhost skyeye] # make install configure - Target parameter specifies that SkyEye analog execution ELF format is executed, and theprefix parameter specifies the installation path of Skyeye. Skyeye's executable after compiling and installed in / usr / local / bin directory: [Root @ localhost skyeye] # ls / usr / local / bin / skyeye -l -rwxr-xr-x 1 root root 2168384 Sep 5 23:55 / usr / local / bin / skyeye Add / usr / local / bin directory to the environment variable PATH, you can run Skyeye in any path in the future: [root @ localhost skyeye] # @ ot = = / usr / local / bin: $ PATH Note: Since SkyEye has no complete function of the instruction, there is "SkyEye Armul_LDC, Not Allow, ...", "SkyEye Armul_LDC, Not Allow, ...", the information, "SkyEye Armul_LDC, Not Allow, ..." Will not affect the normal operation of the application. If you feel that the information is affected, you can comment on the corresponding printf statement of $ SkyEyedir / SIM / Armsupp.c. In this example, the printf statement of the LINE 493 and LINE 579 in the file is annotated. 2) Compile the Linux kernel: Since the Linux-2.6.7 core itself has supported the LubboCK development board, as long as the original default setting is slightly modified.
Note When configuring the core of the embedded development board, you need to set the Arch parameter as ARM: [root @ localhost /] # cd $ kerNeldir [root @ localhost Linux-2.6.7] make Arch = arm lubbock_defconfig [root @ localhost Linux-2.6. 7] Make Arch = ARM MEUNCONFIG ---> Select: General setup (second) ---> Modification (root = / dev / nfs ip = bootp console = ttys0, 115200 mem = 64m) Default kernel command string is: (root = / dev / ram rw initrd = 0xa1000000, 0x01000000 console = ttys0 ,115200 mem = 64M) ---> Select: block defices ---> Modify [] ramdisk support is [*] ramdisk support ---> modification (4096) DEFAULT RAM Disk size (kbytes) is (16384) Default Ram Disk size (kbytes) ---> Modify [] Initial Ram Disk (Initrd) Support is [*] Initial Ram Disk (Initrd) Support ---> Save and exit Modify Command_LINE tells the location and size of the kernel system file system, modifying RAMDisk Support to support the kernel to support ramdisk and specify its size. If you want to support LCD display devices for Lubbock, you must modify it: [Root @ localhost linux-2.6.7] # make arch = arm meunconfig ---> Select: graphics support ---> Modify [] Support for frame Buffer devices is [*] Support for frame buffer devices ---> Modify <> PXA LCD FrameBuffer Support is <*> PXA LCD FrameBuffer Support ---> Modify [] PXA LCD Command Line Parameters is [*] PXA LCD Command Line Parameters ---> Save and exit after completing the kernel configuration, compile the kernel using the Make instruction. Since the kernel runs on an embedded development board, you need to indicate the required cross-compilation toolchain while setting the Arch parameter. It is used herein xscale-gcc-3.3.3: [root @ localhost Linux-2.6.7] # Make / Arch = ARM / Cross_Compile = / usr / local / xscale / 3.3.3 / bin / arm-linux- / ZIMAGE compiled compressed kernel files in Arch / ARM / BOOT /, file name is ziamge: [root @ localhost linux-2.6.7] # ls arch / arm / boot / ziamge -l -rwxr-xr-x 1 Root root 947512 Sep 6 02:49 ARCH / ARM / BOOT / ZIMAGE Note: The value of command_line in the kernel configuration is important. It must be consistent with the contents of the SkyEye that will be mentioned later, otherwise the kernel will not be loaded normally.
The root parameter indicates the location and attribute of the root file system (if the RW parameter is not added, the startup file system bit read-only attribute), the initrd parameter specifies the location and size of the RAMDisk file system. Here, Ramdisk is mapped to 0xA000000 of the memory address, with a size of 0x01000000 (16M). 3) Compile BUSYBOX: Configuring Busybox Remodes the position of the cross tool chain (this example is placed in the / usr / local / arm / bin directory), while BusyBox is immediately started after the BUSYBOX is completed, it is started immediately, so in order to avoid Set the trouble of the shared library link, you should compile busybox as static binary: [root @ localhost /] # CD $ busyboxdir [root @ localhost busybox-1.00-rc3] # Make MenuConfig ---> Select: Build Options ---> Modify [] build busybox as a static binary (no shared libs) is [*] build busybox as a static binary (no shared libs) ---> modify [] do you want to build busybox with a cross compiler? [* ] Do you want to build busybox with a cross compiler? (/ Usr / local / arm / bin / arm-linux-) Cross Compiler prefix ---> Save and exit compile according to your needs ---> Save and exit compilation After installing busybox: [Root @ localhost busybox-1.00-rc3] # make [root @ localhost busybox-1.00-rc3] # make install generated executable executive in busybox-1.00-rc3 / _install directory [root @ LocalHost Busybox-1.00-RC3] # ls _install -l drwxr-xr-x 2 root root 4096 Sep 6 17:49 bin lrwxrwx 1 root root 11 Sep 6 17:49 Linuxrc -> bin / busybox drwxr-xr-x 2 root Root 4096 Sep 6 17:49 sbin drwxr-xr-x 4 root root 4096 Sep 6 17:49 usr [root @ localhost busybox-1.00-rc3] # ls _install / bin / busybox -l -rwxr-xr-x 1 root root 931272 Sep 6 17:49 _install / bin / busybox Note: If BusyBox is compiled into binary files to shared library links, you need to put the desired shared library in the file. System / lib directory. If you put the shared library in other locations, the system is could not run busybox by could not find a shared library. Since Busybox cannot run, the system's shell cannot load, so you cannot set the ld_library_path variable by using Export or Stenv. The solution is to set this variable in the COMMAND_LINE of the kernel. For example, shared libraries are placed in the / usr / local / arm / lib directory, add ld_library_path = / usr / local / arm / lib to Command_LINE.
4) Compile TinyLogin: In addition to setting the cross-compilation tool chain, modify several parameters in makefile, let TinyLogin use the own Passwd and Shadow library (if you do not use the Tinylogin's own library, Tinylogin Will use the system's function library, but also install the NSS link library in the file system of the development board, more troubles): [Root @ localhost /] # CD $ tinylogindir [root @ localhost tinylogin-1.4] # vi makefile --- > modify DOSTATIC = false to DOSTATIC = true (TinyLogin will be compiled into static binaries) ---> modify USE_SYSTEM_PWD_GRP = true to USE_SYSTEM_PWD_GRP = false (use passwd TinyLogin own library) ---> modify USE_SYSTEM_SHADOW = true to USE_SYSTEM_SHADOW = false (using TinyLogin comes with shadow function library) ---> Modify Cross = CROSS = / usr / local / arm / bin / arm-linux- (set the position of the cross-compilation toolchain) Compile the installation Tinylogin binarily Put in the TinyLogin-1.4 / _Install directory: [Root @ localhost tinylogin-1.4] # make [root @ localhost tinylogin-1.4] # make install [root @ localhost tinylogin-1.4] # ls _install -l Total 12 DrwxR-XR- x 2 root root 4096 Sep 6 19:24 bin drwxr-xr-x 2 root root 4096 Sep 6 19:24 sbin drwxr-xr-x 3 root root 4096 Sep 6 19:24 usr [root @ localhost tinylogin-1.4] # LS _INSTALL / BIN / TINYLOGIN -L -RWSR-XR-X 1 root root 40036 Sep 6 19:24 _install / bin / tinylogin 4.
