i386ex: hangups during initialization

[Jürgen Zeller]

hello everybody,

I'm doing my first steps with RTEMS 4.5 and I have big
problems building RTEMS for i386ex.
During the initialization my system hangs up, so I tried to
find out, what the reason is. I've inserted many 'printk's'
in the rtems_executive_early function to see, how much code
gets processed.
But after a while I found out that the error is not constant at the 
same time or function, it depends for example how much printk's I issue!
But in following illogical manner:
 so more printk's I use so more code I get processed!

I've checked my register settings, my linkcmds and my start.S often
but I can't find the error.


Has anybody an idea what could go wrong in my application?
Could it be a Hardware problem?
I use a bootloader for downloading, could this be the reason? And why?


I have no experience with RTEMS and I would be obliged for every tip I
get.




RAM	0x00000000 .. 0x0003ffff
Flash   0x00080000 .. 0x000fffff
