[ELDK] Need help compiling u-boot for Lite5200

[Detlev Zundel]

Hi Alexej,

Ah, 7 year old material ;)

Although we are currently transitioning to ELDK 5.x, this should still
work, yes.

> Then I just followed the manual:

> $ export CROSS_COMPILE=ppc_82xx-

This should really be ppc_6xx but as the one is a symlink to the
other, both should work.

Did you do an "export PATH"?

Ah, even older sources :)  Lite5200 is supported in current sources, so
you should use that[1] - even top of tree fresh from git should work.

Nope, this is a pilot error, the infrastructure is ok. Just setup PATH
and CROSS_COMPILE in the shell from which you call make and be sure to
export all of them.

Happy hacking!
