IMX8X ADC_IN0 Configuration Problem

jack_huang1 — Sun, 23 Apr 2023 07:31:39 GMT

Dear：

In IMX8QX scheme, ADC_IN0 needs to be multiplexed as GPIO. When configured as output, no matter the output is 0 or 1, the voltage on the pin does not change. The configuration is as follows:

SC_P_ADC_IN0_LSIO_GPIO1_IO10 0x0600006C /*phy1_reset*/

SC_P_ADC_IN0_LSIO_GPIO1_IO10 0x0600004C /*phy1_reset*/

Please confirm whether there is a problem when ADC_IN0 is reused as gpio. Because other pins we normally configure for gpio multiplexing have no problem, but now this ADC_IN0 after multiplexing control has no reaction?

Thank you!

Best Regards!
