U-Boot hangs in relocate_code after sw reboot

U-Boot hangs in relocate_code after sw reboot

[Jaka Močnik]

hello!

I don't really know if this mailing list is the proper place to direct
questions regarding U-Boot, but I've seen some preceding posts about it,
so I thought I'd ask...

I've ported U-Boot over to a custom MPC8560 (PQ3) based board - it works
well, except that after a sw reboot (from linux kernel or u-boot
itself), it only gets to the part where it relocates itself to RAM and
then hangs - the last debug output is 

Relocating code to 07fd4000...

and the famous

Now running in RAM - U-Boot at: 07fd4000 never shows up.

has anyone experienced similar problems? any hints on what to look at?

regards,
	jaKa

Let's start with:  The U-Boot list is over at:
    u-boot-users <u-boot-users@lists.sourceforge.net>

Good...  So, what version did you start with?
And how custom is it?  We just might need a few more details here... :-)

There were some early releases of 8560 U-Boot code that
didn't do SW Reset right.  Let's make sure we are running
a modern U-Boot for the 85xx first.

There are some U-Boot FAQs down this line too.

Yes, this is the wrong list, you should use the u-boot list (see 
SourceForge u-boot page).
   http://sourceforge.net/projects/u-boot/

Your question is a FAQ.  Please read the DULG:
   http://www.denx.de/twiki/bin/view/DULG/Manual
especially the FAQ:

This is better posted to the u-boot-users list=20
(u-boot-users@lists.sourceforge.net)
