RPX Lite w MontaVista 1.2

Hi,

I have downloaded the MontaVista CDK 1.2 and installed everything for the
RPX lite. I followed the documentation and I can load the s record image
into an RPX Lite board (850SR) using tftp no problem - I did a memory dump
and the first few bytes match the srec file. When I type go 200000 to try to
start the kernel the board just goes off with the fairies. I enabled the bus
monitor and the board resets so I assume it's accessing memory outside of
what's configured. The RPX lite is running the PlanetCore Boot Loader v1.01.
Here are the keys for the RPX lite :

Baud                                   = 9600
Multiplier  (Clock multiplier)         = 6
Board                                  = LICC_E
Revision                               = BW
Processor                              = 850
Variant                                = SR
DRam        (MBytes on board dram)     = 16
Cols        (On board dram columns)    = 10
NVRam       (KBytes on board NV Ram)   = 0
Sttm        (Degrees C*10)             = 131
Twirl                                  = Y
ICache                                 = N
SYPCR                                  = FFFFF080
RAMtest                                = Y
RestoreCE   (Cannot go to ram if set)  = N
SerOut      (Serial output of loader)  = Always
RS232       (Enable rs232 drivers)     = Y
IP                                     = 192.168.0.122
Target                                 = 192.168.0.89
File                                   = zImage
ENET                                   = 0010EC000DB4
TftpRAM                                = High
Start                                  = 0
Format                                 = NetSrec
Autoboot                               = N

The memory map is
IMMR = 0xFA200000
    Address  Mask     Size WP Mach
CS0 FC000000 FC000000 Word N  GPCM
CS1 00000000 FF000000 Word N  UPMA
CS2 (not used)
CS3 FA400000 FF7F8000 Word N  GPCM
CS4 (not used)
CS5 (not used)
CS6 (not used)
CS7 (not used)

Any help would be appreciated.

Hmmm....I left some debug stuff in arch/ppc/mbxboot/embed_config.c....
Edit that file, remove the:

	{
		int i;
		cp = (u_char *)0xfa000000;

		.....
	}

piece of code that appears early in the function rpx_cfg().  If you
don't have a board with NVRAM, this will certainly fail.

Sorry about that, let me know how it goes.
