Hi,
	I am using a PQ2FADS-ZU board with u-boot.I have an option to change
jumpers and DIP Switches for setting the local bus to PCI mode.However
U-boot refuses proceed after Initialising DRAM.I went through the source and
initialises the LSDRAM after reading the BCSR.

Any pointers from the experts here would be really helpful.

TIA,

Cheers,

.Bharath.

HI !

 I have a problem with device initialisation in the kernel (all up and
running
 in u-boot) , so I wanted to have u-boot load the kernel, decompress it but 
 then not actually start it -  reading the u-boot manual I found that one 
 should use autostart no. The sequence I used was:

   setenv ipaddr 192.168.1.250
   setenv serverip 192.168.1.34
   tftpboot 0x350000 vmlinux.PPCBoot
   setenv autostart no 
   bootm 0x350000 

 but that simply kicks up the kernel and ends up in a panic becaues the 
 network and serial port initialization don't work in the kernel which I'm 
 trying to debug that - but I can't seem to stop the kernel with a
breakpoint
 as the xilinx tools (XMD) simply does not set it, so I wanted u-boot to
stop
 at the kernel entry and step it from there - no luck though.

 So how can I get u-boot to just do the decompression but not pass control
to 
 the kernel ?

thx !
