[U-Boot-Users] PROBLEM ABOUT PORTING U-BOOT-1.1.4 TO INTEL PXA255 BOARD

[Paradise]

hi,u-boot-users

	I am trying to port u-boot-1.1.4 to my board,But i meet some problems.

Main resources of the board:
		CPU : INTEL PXA255 400MHZ
	  FLASH : INTEL TE28F128J3C150 32M
	  SDRAM : SAMSUNG 64M

Problem description :	
	According to the Lubbock developing board and the manual of my board , i have modified some files of uboot and compiled correctly(u-boot.bin is about 108K).
	Because i have no any hardware emulator, so i write a simple program to trace the uboot running, i find it stop in board_init() function(/u-boot-1.1.4/board/xhyper255/xhyper255.c).

int board_init (void)
{
	DECLARE_GLOBAL_DATA_PTR;

	/* memory and cpu-speed are setup before relocation */
	/* so we do _nothing_ here */

	/* arch number of cerf PXA Board */
	gd->bd->bi_arch_number = MACH_TYPE_XHYPER255;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~It stops here!!!!  
			
	/* adress of boot parameters */
	gd->bd->bi_boot_params = 0xa0000100;

	return(0);
}

The simple program writes as follows:
asm("mov r11,#0x08300000;\
	mov r0,#0x0F;\
	strh r0,[r11];\
        \
	ldr r1,=0x40A00010;\
	ldr r2,=0x40A0000C;\
	mov r0,#0x0;\
	str r0,[r1];\
	nop;\
	nop;\
	nop;\
	nop;\
	nop;\
	nop;\
	nop;\
     	mov r0,#0x780000;\
	str r0,[r2];\
        \
      	ldr r1,=0x40A0001C;\
	mov r0,#0x8;\
	str r0,[r1];\
	\
delay1:;\
	ldr r10,=0x40A00014;\
	ldr r0,[r10];\
	tst r0,#0x8;\
	beq delay1;\     	ldr r11,=0x40A0001C;\
	ldr r4,[r11];\
	and r4,r4,#0x07;\
	str r4,[r11];\ 
        \
	str r0,[r10];\
        \
	ldr r1,=0x40A00010;\
	ldr r2,=0x40A0000C;\
	mov r0,#0x0;\
	str r0,[r1];\
	nop;\
	nop;\
	nop;\
	nop;\
	nop;\
	nop;\
	nop;\
 	mov r0,#0x780000;\
	str r0,[r2];\
        \
      	ldr r1,=0x40A0001C;\
	mov r0,#0x8;\
	str r0,[r1];\
	\
delay2:;\
	ldr r10,=0x40A00014;\
	ldr r0,[r10];\
	tst r0,#0x8;\
	beq delay2;\
        \
     	ldr r11,=0x40A0001C;\
	ldr r4,[r11];\
	and r4,r4,#0x07;\
	str r4,[r11];\
        \
	str r0,[r10]");

Appreciate any help.

when executing "gd->bd->bi_arch_number=MACH_TYPE_XHYPER255;" or other similiar sentences("gd->bd->**=**"), the progress was terminated. But when executing other sentences such as "gd->env_addr  = (ulong)&default_environment[0];gd->env_valid = 0;"(these sentences are in function env_init(),common/env_flash.c),the progress can do them well.

Does anyone meet this problem,or give some useful debug methods without any hardware emulator? Appreciate for any help.

Hi Scut Paradise,

If you think you're going to get more help the more times you resend you
message, you are probably wrong.

The fact that the "DECLARE_GLOBAL_DATA_PTR" is defined inside board_init
indicates that you are not using top of the tree U-Boot. Please switch
to current sourcen first of all. The DECLARE_GLOBAL_DATA_PTR statement
needs to be defined globally due to gcc misbehaviour.

Use the newest version of U-Boot from the git repository. The version
you are using is old.
