Hi NXP Team,
I just enable 'adc1' in our device tree, but the system reponse the calibration failed.
What could be the reason?
&adc1 {
vref-supply = <®_vref_1v8>;
status = "okay";
};
root@imx93afee320a1:/sys/bus/iio/devices# dmesg| grep adc

Which version BSP are you using? Are you using the NXP 93EVK BOARD?
