[U-Boot-Users] uboot and Pci in Pq2fads-ZU

[Bharath]

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 !

Which interface do you use pci or local bus?
If you use pci, you will add the pci stuff (see board: pm828) in your board file and undef the local bus sdram settings . 
Good luck

If you want to use PCI, try the 8266ADS board port instead (it should be
the same as the PQ2FADS board)
Your boot hangs because it is trying to initialize the local bus SDRAM,
and uou are trying to se it as PCI.

[U-Boot-Users] uboot and Pci in Pq2fads-ZU

[Bharath]

Hi Marco/Rune,

		Thank you very much for the inputs. I tried undef'ing the
Local bus , still dosent seem to work, infact that was the first thing i
did. I have been successful in bringing up u-boot on my target board which
also has a PCI Interface on the local bus (it dosent have a LSDRAM there).
Am i missing something here ? Any BCSR's or PCI registers to be configured
for PQ2? 

Yeah sure will try adding the PCI stuff to this board and see if it works.

I was also wondering if anyone has got PCI working on PQ2FADS-ZU board with
u-boot ?

Thanks once again for the help,

Cheers,

.Bharath.

Local bus initialisation is under #ifdef CFG_LSDRAM_BASE so if this is
not defined, the local bus initialisation code won't even be compiled in.

You have to select PCI or Local bus using jumper JP9. The jumper's
setting is reflected in BCSR3 and used by the code to set some
registers. If JP9 selects Local bus but you try to initialise PCI it
should fail.
