We would like to build the TF-A image with a different muxer setting
for i2c4. The usual setting is:
i2c4_pins_a: i2c4-0 {
pins {
pinmux = <STM32_PINMUX('Z', 4, AF6)>, /* I2C4_SCL */
<STM32_PINMUX('Z', 5, AF6)>; /* I2C4_SDA */
bias-disable;
drive-open-drain;
slew-rate = <0>;
};
};
our setup:
i2c4_pins_a: i2c4-0 {
pins {
pinmux = <STM32_PINMUX('H', 11, AF6)>, /* I2C4_SCL */
<STM32_PINMUX('H', 12, AF6)>; /* I2C4_SDA */
bias-disable;
drive-open-drain;
slew-rate = <0>;
};
};
If we use the changed pin muxing we get no signal output on those pins.
My question, is it possible to change the pin muxing
or is the muxing for I2C4 fixed for the TF-A build ?
