AM3352: I2C error

newuser

Part Number: AM3352

I am getting the following error for I2C during bootup, any suggestion?

[ 0.208190] omap_i2c 44e0b000.i2c: could not find pctldev for node /ocp/l4_wkup@44c00000/scm@210000/pinmux@800/pinmux_i2c0_pins, deferring probe

Hi newuser,

This is actually not a critical issue. It usually indicates that the kernel will return to device (in your case i2c) pinmuxing later.

Just to be sure after your board boots, you can check with devmem2 the corresponding pinctrl registers.
Also another possibility is that these pins were already configured (i.e. in u-boot), so can you also check this?
