https://devzone.nordicsemi.com/f/nordic-q-a/128178/unable-to-recover-nrf52840I&#39;m programming a batch of 100 NRF52840 devices (new ISP1807-LR modules), and I&#39;m unable to recover or program several of them. Most work fine, and I&#39;ve never seen this issue until this batch. Does this sound like there is an error with the chips?

This leads me to wonder if there is an issue with some of the modules or if they somehow have gotten damaged.</p><div style="clear:both;"></div>
