How to get barebox for 'KARO's Starterkit 5'
|
|
--------------------------------------------
|
|
|
|
Using the default configuration::
|
|
|
|
make ARCH=arm tx28stk5_defconfig
|
|
|
|
Build the binary image::
|
|
|
|
make ARCH=arm CROSS_COMPILE=armv5compiler
|
|
|
|
**NOTE:** replace the armv5compiler with your ARM v5 cross compiler.
|
|
|
|
**NOTE:** to use the result, you also need the following resources from Freescale:
|
|
|
|
* the 'bootlets' archive
|
|
* the 'elftosb2' encryption tool
|
|
* in the case you want to start barebox from an attached SD card
|
|
the 'sdimage' tool from Freescale's 'uuc' archive.
