nRF5340 - How to change clock freq of app core on the flyhttps://devzone.nordicsemi.com/f/nordic-q-a/59697/nrf5340---how-to-change-clock-freq-of-app-core-on-the-flyHi, What is the suggested way to switch between 64MHz and 128MHz on the application core? Normally I want to run at 64MHz, but sometimes boost it to 128MHz. Is there additional setup needed to properly propagate the clock change for example to, TWIMen-USTelligent Community 13Fri, 03 Apr 2020 01:00:40 GMTRE: nRF5340 - How to change clock freq of app core on the flyhttps://devzone.nordicsemi.com/thread/243281?ContentTypeID=1Fri, 03 Apr 2020 01:00:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a3ded4c-cf94-4450-b617-86d3a3369f36navigator<p>Thank you haakonsh!</p><div style="clear:both;"></div>RE: nRF5340 - How to change clock freq of app core on the flyhttps://devzone.nordicsemi.com/thread/243089?ContentTypeID=1Thu, 02 Apr 2020 07:16:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f40fc6a-353e-4201-87c1-07357123b637haakonsh<p>See&nbsp;<a href="https://infocenter.nordicsemi.com/topic/errata_nRF5340_EngA/ERR/nRF5340/EngineeringA/latest/anomaly_340_4.html?cp=3_0_1_0_1_1">[4] CLOCK: Changing application core frequency register HFCLKCTRL requires additional register initialization</a>.<br /><br />The peripheral clocks are fixed at their frequency regardless of HFCLKCTRL.</p><div style="clear:both;"></div>
