How to get the binary image
|
|
---------------------------
|
|
|
|
Configure with the default configuration::
|
|
|
|
make ARCH=arm a9m2440_defconfig
|
|
|
|
Build the binary image::
|
|
|
|
make ARCH=arm CROSS_COMPILE=armv4compiler
|
|
|
|
**NOTE:** replace the armv4compiler with your ARM v4 cross compiler.
