Hi,
Am trying to configure I2C2 on a custom board on AM5728. The device tree entries is as follows.
********************************************************************
i2c2_pins_default: i2c2_pins_default {
pinctrl-single,pins = <
0x408 (PIN_INPUT_PULLUP | MUX_MODE0) /* i2c2_sda BALLNUMBER:C25*/
0x40C (PIN_INPUT_PULLUP | MUX_MODE0) /* i2c2_scl BALLNUMBER:F17*/
>;
};
&i2c2 {
status = "okay";
clock-frequency = <400000>;
};
********************************************************************
After this, i see that i2c1 is shown in /dev whereas when i try to detect the i2c bus for any slave devices by i2cdetect -r 1, i see the error as below:
[ 37.867042] omap_i2c 48072000.i2c: controller timed out
-- [ 38.907038] omap_i2c 48072000.i2c: controller timed out
-- [ 39.947037] omap_i2c 48072000.i2c: controller timed out
-- [ 40.987036] omap_i2c 48072000.i2c: controller timed out
We have followed the similar configuration for i2c3 & 4 and it is working well.
Is there anything am missing out here?
Best Regards,
Sri
