Compilation of blob of cainiao

Cainiao's blob compilation-general Linux technology-Linux programming and kernel information. The following is a detailed description. System Configuration: fedora 7 + arm-linux-tools-20061213 + blob-for3000 + uClinux-dist-20041215

Compilation steps:

First, rewrite the blob program based on the hardware of the target system.

Compile uClinux-dist (obtain the Kernel configuration source file)

Then:

Configure the cross-compilation environment

# Tar zxvf arm-linux-tools-20061213.tar.gz

# Ls

Usr

# Cp usr/usr

/* This step is required. Instead of this step, the unzipped usr folder is directly written into the PATH, and the results can be correctly displayed using which, arm-linux-gcc-v, and so on, but it cannot be used to compile hello. the reason is that usr/local/arm-linux/lib/libm. so.6 is a link file. The link address is located in/usr/loacl in the system directory, rather than in usr/local */

########## Compile the blob-for3000 ###########

# Vi build-s3c44b0/* here is mainly to modify "-- with-prefix-linux = (kernel source file location )"*/

#./Build-s3c44b0

/* If the compiled Kernel File is in the blob-for3000/src/blob, download it to the target system */

####### Compile the blob-2.05-pre2 ###########

#./Configure -- with-board = target board model -- with-linux-prefix = kernel source file location

# Make

/* If the compiled Kernel File is in the blob-2.05-pre2/src/blob, download it to the target system */
