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

For your reference, attached is the BSP porting guide. There is talk about porting I2C. Although it is for i.MX6, the porting is similar to i.MX53.
