https://devzone.nordicsemi.com/f/nordic-q-a/92373/cannot-flash-nrf52811-sometimesHello, I have a problem regarding production flashing a nRF52811 device. We are using a Segger Flasher Compact, but I also tried a Segger J-Link Compact. To flash we are using a ubuntu PC with nrfjprog with the following version: Sometimes, but noten-USTelligent Community 13Wed, 28 Sep 2022 13:06:14 GMThttps://devzone.nordicsemi.com/thread/388360?ContentTypeID=1Wed, 28 Sep 2022 13:06:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:36dbcee3-5b1d-4040-89d3-a4b999a2e240H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>Q1: Does this issue occur on one device, or with&nbsp;all devices?</p> <p>Q2: If it works when using a slower clock speed, it can indicate that there&#39;s an issue electrically (long wires, high capacitance on the lines, or similar). In your design, is the SWD pins directly routed to the programming header? Ie. is there any capacitors or resistors on these lines?</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
