I2C3 bus verification on SMD design of i.MX53

Hi!  

We design a board based on i.MX53 SMD design.  In addition to the existing VGA connector wired to I2C3, we wired another LCM module with I2C bus to 5V VGA_I2C and then to the 3.3V I2C3 bus.  However, we are not sure the I2C3 bus works on SMD or not.  Could anyone share his/her experience on using I2C3 bus?  

 

Also, we know there is a I2C probe command within uboot.  Could anyone tell us how to use i2c related commands in uboot to test chips on I2C3 bus? 

 

Thanks!

 

Vincent
