[U-Boot-Users] A problem with u-boot on smdk2410 used nand flash(smart media card)

[Ada Wu]

Hi all,
I have a problem with u-boot on smdk2410, i used a nand flash(smart media card).
I had make an "u-boot.bin " image, and download with jtag to the nand
flash. But, that was no any out put signal on the screen.
I just used the "make smdk2410_config", but I didn't change any file.

After that method failed. Then i thought, how can I enable the nand flash?
So I added some things in "smdk2410.h", which are 
CONFIG_COMMANDS \
               (CONFIG_CMD_DFL	 | \
                CFG_CMD_CACHE	 | \
	CFG_CMD_NAND	 | \
	CFG_CMD_REGINFO  | \
	CFG_CMD_DATE	 | \
	CFG_CMD_ELF)

Is that a correct direction to boot on nand flash?
I assume that is a correct direction, but that is some error with compiling.
Such constants or marcos are not defined:
#define SECTORSIZE 512
#define ADDR_COLUMN 1
#define ADDR_PAGE 2
#define ADDR_COLUMN_PAGE 3
#define NAND_ChipID_UNKNOWN 0x00
#define NAND_MAX_FLOORS 1
#define NAND_MAX_CHIPS 1
#define NAND_WAIT_READY(nand)
#define WRITE_NAND_COMMAND(d, adr)
#define READ_NAND(adr)
..............................etc....

Where can I find the header file for smdk2410 with nand flash?
or How can i find make such definition for nand flash? and where
should i add such definition?
Thanks!!

What makes you think that this should work?

Create one.

Have a look at what other boards with NAND support are doing, try  to
understand this, and then copy and adapt these settings.

For a start, I recommend to RTFM (see doc/README.nand).

Best regards,

Thanks for you suggestion. 
I created a new header file for some definitions of nand flash.
That might work, but there is a compile error that i don't know how to solve it.
When compiled(make) to the last "u-boot" binary file, then that can
not find `__readwrite_bug'.


The error message is :

/usr/local/arm/2.95.3/lib/gcc-lib/arm-linux/2.95.3 -lgcc --end-group \
                -Map u-boot.map -o u-boot
common/libcommon.a(cmd_nand.o): In function `nand_write_page':
/home/music/u-boot/u-boot-1.1.1/common/cmd_nand.c:1066: undefined
reference to `__readwrite_bug'
/home/music/u-boot/u-boot-1.1.1/common/cmd_nand.c:1080: undefined
reference to `__readwrite_bug'
make: *** [u-boot] Error 1

I think that problem comes from /asm-arm/io.h
And I can not find any function about "__readwrite_bug()". so I can't slove it.
My u-boot version is 1.1.1.
What can I do for this error?
Thanks!!
