analogSetAttenuation(ADC_11db); bricked my ESP32-WRover-B

Was trying to fix an issue with read analogue getting ghost values even with pulldown resistors, so made a quick sketch.
Tried adding analogSetAttenuation to the test sketch to fix it, now the moduel is dead, ntoeven being seen on the com port.

Code: Select all
const int
C1 = 25,
C2 = 33,
C3 = 32;
int read1,read2,read3;
void setup() {
Serial.begin(115000);
// put your setup code here, to run once:
pinMode(C1, INPUT);
pinMode(C2, INPUT);
pinMode(C3, INPUT);
analogSetAttenuation(ADC_11db); <adding this bricked the module
}
void loop() {
// put your main code here, to run repeatedly:
read1 = analogRead(C1);
read2 = analogRead(C2);
read3 = analogRead(C3);
Serial.println((String)read1+":"+(String)read2+":"+(String)read3);
delay(100);
}
