i dont see any i2c bus driver loaded. you must load one yourself.

--- Sonic Zhang 2010-09-30 05:24:37

Can't replicate on 2010R1-RC1 kernel. May be you forgot to connect the LCD addon

to the PPI port?

--- angelia wu 2010-10-12 21:56:03

i remember i have connected the LCD on the board.

but now i test it again and found that the error disappear.

so i closed it.
