Hi All, I'm trying to build u-boot with i2c support for a mba2440 board. U- boot version is mba2440-uboot1.1.1.
you use a very old version of u-boot, you should update to current version.
In mba2440.h config file i have selected the i2c commands :
I cannot find such a config file in mainline ...
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 Regards Yannick

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