Hi,

 

I would like on a mx53 QSB the i2c1 on pin :

 

IMX53_PAD_EIM_D21_I2C1_SCL,

IMX53_PAD_EIM_D28_I2C1_SDA,

 

I've added this two line in mx53_loco_pads[] in arch/arm/mach-mx5/board-mx53_loco.h (in linux 2.6.38 from freescale). And remove this line :

 

MX53_PAD_EIM_D21__IPU_DISPB0_SER_CLK,

 

When the linux boot /dev/i2c-0 is created but I've no signal on scl or sda pin.

 

What is missing in my modification?

 

Cordially,

Cyril crocquesel
