Uboot compilation confusions

Uboot compilation puzzles-general Linux technology-Linux programming and kernel information. The following is a detailed description. Environment variable configuration during compilation

Modify the Makefile in the uboot directory and set

Ifeq ($ (ARCH), arm)

CROSS_COMPILE = arm-Linux-

Endif

Modify

Ifeq ($ (ARCH), arm)

CROSS_COMPILE =/usr/local/arm/2.95.3/bin/arm-linux-(2.95.3 installation directory)

Endif

As not mentioned in other articles, make nano2410_configt can pass

PATH modification is to modify the/etc/bashrc File

Export PATH = $ PATH:/usr/local/arm/2.95.3/bin/arm-linux-

But modify # vi ~ /. Bashrc (in the uboot directory)

Export PATH =/usr/local/arm/2.95.3/bin/arm-linux-: $ PATH

After modification, run the command # source. bashrc.

// View the PATH value: # echo $ PATH

Try it tonight.

Another problem is that

Make CROSS_COMPILE = arm-linux-

The arm-linux-gcc command is not found.

However, make directly does not know the difference.
