Hi All,
I'm trying to build u-boot with i2c support for a mba2440 board. U-boot version is mba2440-uboot1.1.1.
In mba2440.h config file i have selected the i2c commands :
#define CONFIG_COMMANDS \
(CONFIG_CMD_DFL | \
CFG_CMD_CACHE | \
CFG_CMD_NAND | \
CFG_CMD_PING | \
/*CFG_CMD_EEPROM |*/ \
CFG_CMD_I2C | \
/*CFG_CMD_USB |*/ \
CFG_CMD_REGINFO | \
CFG_CMD_DATE | \
CFG_CMD_FAT | \
CFG_CMD_MMC | \
CFG_CMD_NET | \
CFG_CMD_ELF)
I get the following error when trying to build:

I'm new to u-boot programing, am i missing something in the config file?
Thanks

you use a very old version of u-boot, you should update to current
version.

As the error message says, some symbols are missing ... if you want to
use i2c, you must enable through a CONFIG option, which i2c driver you
want to use on your hardware. I cannot help you more here, because I
do not know anything about your board.

Yep!

Actually i got that u-boot version from our vendor. They ported u-boot
to make it work with the mba2440 board(s3c2440 processor) they are
selling, but they didn't submit it as patch, i guess that's why i
have all files for that board and you don't in mainline.
I've downloaded u-boot-2011-12 and tried porting it to the mba 2440
hardware by adding configuration options and files but i had errors
when compiling with arm-linux-gcc cross compiler. I think i'll just
try to fix the missing symbols problem using the old u-boot version

Yannick
