NRFX Oscillator will never allow setting bypass for LFXO

Hi,

Indeed it doesnt look like it was included in the nrfx version that is included with NCS v2.7.0. But the fix has been added in nrfx 3.6.0, so you can pull that version of nrfx.

Hi Jared, I am wondering when this fix will be in the main branches of the nrfx repo? NCS 2.7.0 released and this bug still appears to be present.

Hi,

This is indeed a bug. Temporary fix would be to modify it to check the mask instead of the typedef like this:

#if defined(OSCILLATORS_XOSC32KI_BYPASS_BYPASS_Msk) || defined(__NRFX_DOXYGEN__)
/** @brief Symbol indicating whether LFXO bypass is present. */
#define NRF_OSCILLATORS_HAS_LFXO_BYPASS 1
#else
#define NRF_OSCILLATORS_HAS_LFXO_BYPASS 0

Modifying the register directly produces expected results. Glad the feedback is making its way through the channels. Thanks!

Hi there,

I think you're right, let me double check with the developers.

In meantime you can try to set the register directly instead.
