NRF52820 Custom board is found by J-Link but seems to hang when starting CPU.https://devzone.nordicsemi.com/f/nordic-q-a/91833/nrf52820-custom-board-is-found-by-j-link-but-seems-to-hang-when-starting-cpuHello, I&#39;ve recently created a custom board based on the NRF52820 which is configured based on the datasheet. I&#39;m using an NRF52833 DK OB J-Link to program the device. The J-LINK does detect the NRF52820 as well as read the NRF52820 memory whichen-USTelligent Community 13Mon, 12 Sep 2022 07:49:23 GMTRE: NRF52820 Custom board is found by J-Link but seems to hang when starting CPU.https://devzone.nordicsemi.com/thread/385639?ContentTypeID=1Mon, 12 Sep 2022 07:49:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd65f00c-03c5-4fa5-89c9-3e7c908819bcBendik Heiskel<p>Hi,</p> <p>The blinky example code uses a external 32.768kHz crystal connected to P0.00 and P0.01 as the default LFCLK source. The system will wait until the crystal is started before continuing. Since you are not using a external crystal you will have to switch the source for the LFCLK to the internal RC oscillator.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
