Hello everyone, when I designed the board using the BCM43438, I started the WL_REG_ON this pin and thought that the chip should have worked properly and that the measurement of each voltage was correct. But when I measured the voltage at both ends of the crystal, I found that there was no voltage, what was the reason? I use what seems to be the official recommendation of 37.4MHz crystal and 12pF capacitor.
