dear all,
I know this might be an old question for u guys,
but I really met some troubles within it.

My platform is:
CPU : Xscale pxa255
OS : Windows CE .Net 4.2
Flash : 32MB
SDRAM : 128MB (32MBX4)


Now I want to set the configuration of 128M SDRAM.
following some suggestions,I modified the some files below,
but it does not work..
now,I list my main modification:
//////////////////////////////////////
config.bib
//////////////////////////////////////
MEMORY

/////////////////////////////////

DCD 0x00000000, 0x00000000, 0


then,I changed xsc1.h,xsc1.inc,xsc1bd.h,xsc1bd.inc to
be in sync with config.bib and OEMAddressTable,
and I checked a lot ,there's no problem with them.
///////////////////////////////////////////////////////////////////////
and in memdefs.h, I was a little confused about the codes below:
and I modified the two values which I marked to sync.
///////////////////////////////////////////////
#ifndef SABINAL
//
// Cotulla-32 Defs
//


#define MEM_BASE_PHYSICAL 0xA3CB8000
#define MEM_BASE_C_VIRTUAL 0x87CB8000 //modifed
#define EDBG_PHYSICAL_MEMORY_START 0x87F8D000 //modifed
#else
//
// Sabinal Defs
//this seems not used,so I do not modify the value
#define MEM_BASE_PHYSICAL 0xA1CB8000
#define MEM_BASE_C_VIRTUAL 0x81CB8000
#define EDBG_PHYSICAL_MEMORY_START 0x81F8D000
#endif


///////////////////////////////////////////
I also changed the value in xsc1bd.inc
MDCNFG_VAL EQU 0x19C319C3
; Setup default MDCNFG value for 128MB SDRAM
///////////////////////////////////////////
in the end,according to K.S.huang's advice,i modified file fwxsc1.s
; enable sdram bank 0 if installed (must do for any populated bank)
orr r3, r3, #MDCNFG_DE0
;4.28 add
orr r3, r3, #MDCNFG_DE1
;add above


and also changed some uart address in platform.reg
such as:
;-------------------------------------------------------------
; Serial1 : FFUART
;-------------------------------------------------------------
; @CESYSGEN IF CE_MODULES_SERIAL
IF BSP_NOSERIAL !
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial]
"Dll"="xsc1bd_serial.Dll"
; "IoBase"=dword:a6300000 ;FFUART_BASE_U_VIRTUAL
"IoBase"=dword:a8300000 ;FFUART_BASE_U_VIRTUAL
.................
///////////////////////////////////////////////
when all of them had done,I download the NK.bin,
and the debug information shows:


rom_offset=0x0.
Found pTOC signature.
ROMHDR at Address 800B8044h
RomHdr.ulRAMStart=81C50000h RomHdr.physfirst=800B8000h.

OEMInitDebugSerial using UART2
Windows CE Kernel for ARM Built on Mar 13 2003 at 22:54:19
ProcessorType=02d0 Revision=6
sp_abt=ffff5000 sp_irq=ffff2800 sp_undef=ffffc800 OEMAddressTable =
800b9ef4


as u see,my system hung at last,
if normal,sp=ffffc7cc should be printed behind
OEMAddressTable = 800b9ef4
but now,system hung there....
and Platform builder printed the word"Kernel debugger is waiting to
connect with target."


Anybody has experience ?
could u give me some advice?
I so appreciate it, thank u a lot.
