https://devzone.nordicsemi.com/f/nordic-q-a/112205/nrf5340-hardware-boot-problemsRegarding the design issues with the nRF5340, I have adopted the nrf5340_qkaa_config3 design scheme from the hardware design package. However, after testing, I found that while it allows programming when I supply 3.3V to the VDD_nRF network, there isen-USTelligent Community 13Wed, 19 Jun 2024 11:48:39 GMThttps://devzone.nordicsemi.com/thread/489495?ContentTypeID=1Wed, 19 Jun 2024 11:48:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e04f1f07-8eba-462f-9105-4807c1d0e9a9helsing<p>Hello cweib,</p> <p>Is the optional 32kHz crystal mounted?
