[U-Boot-Users] A problem with u-boot on smdk2410 used nand flash(smart media card)
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.
or How can i find make such definition for nand flash? and where should i add such definition?
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).

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!!
