How to config the IO pin in Zephyr?

[RTang.1]

I am trying to porting Zephyr to my own board which is designed on stm32f429i_disc1.

So I copy the folder zephyr\boards\arm\stm32f429i_disc1 for my porting.

​

A problem comes up when I am configuring the IO pin for I2C2.

​

In stm32f429i_disc1.dts, the i2c2 is configured as following.

&i2c2 {

pinctrl-0 = <&i2c2_scl_pb10 &i2c2_sda_pb11>;

status = "okay";

clock-frequency = <I2C_BITRATE_FAST>;

};

​

But my board uses PH4 and PH5 for I2C2, so I change the config as following.

&i2c2 {

pinctrl-0 = <&i2c2_scl_ph4 &i2c2_sda_ph5>;

status = "okay";

clock-frequency = <I2C_BITRATE_FAST>;

};

when I build it, an error comes up to tell "i2c2_scl_ph4/i2c2_sda_ph5" are not defined.

I did some search but cannot solve the problem, could you please give me a hand?

Sorry for late feedback. Please have a new try after running "west update".

Also, if you need support on Zephyr, don't hesitate to join Zephyr Slack channel (you can find the links here: https://zephyrproject.org/contact-us/)

There's a dedicated #stm32 channel where you'll find an active community to provide feedback on zephyr specifics.
