Hello,
I'm debugging Sitara Linux SDKv8 for my custom board based on AM335x Starter Kit. My board uses I2C1 instead of I2C0. So I need to change pin configuration for I2C to connect TPS65910 and something. I modified dts file below and saw attached bootlog file from SD boot by same pin configuration for MMC0. The log is stopped at the bottom. Please give me some advice.
< am335x-evmsk.dts >
i2c1_pins: pinmux_i2c1_pins {
pinctrl-single,pins = <
0x180 (PIN_INPUT_PULLUP | MUX_MODE3) /* i2c1_sda.i2c1_sda */
0x184 (PIN_INPUT_PULLUP | MUX_MODE3) /* i2c1_scl.i2c1_scl */
>;
};
&i2c1 {
pinctrl-names = "default";
pinctrl-0 = <&i2c1_pins>;
status = "okay";
clock-frequency = <400000>;
tps: tps@2d {
reg = <0x2d>;
};
};
Regards,
Kazu
