[U-Boot-Users] U boot scripting / stand alone program capabilities

[Gerrit Van de Velde]

Dear U boot users,

I've read the DULG manual about the U boot scripting capabilities and
successfully run the hello_world.srec example, but now i want to replace
the hello world program with one of my own programs. How can I compile
my own program ? No info is available in the manuals I've read. I've
already tried with the Makefile that's included with the examples and
set ARCH to ppc and TOPDIR to ../u-boot/ (for config.mk) but that fails.

(I am using the MPC5200 Lite - Icecube)

Any pointers are welcome..

Note that these are two different issues.

Scripting (i. e. the capability to run canned command sequences)  has
nothing  to  do  with standalone programs like those in the examples/
direcotry.

The simple way: just place your code in the examples/  directory  and
add a new target to examples/Makefile; alternatively, you can add you
code  to your board specific directory and adjust the makefile there.
See  for  example  boards/trab  which  includes  some  extra  targets
(trab_fkt.srec, trab_fkt.bin) for standalone hardware test routines.


Best regards,
