https://devzone.nordicsemi.com/f/nordic-q-a/121957/cannot-program-pcb---the-write-access-failed-but-no-cause-could-be-determinedHi there, I am currently trying to program a custom PCB equipped with the BMD-380 that has the nrf52480 inside. Sadly, I am now stuck for days with the same issue: It simply will not write anything to memory.

You were right! The reset pin was indeed active due to a faulty circuit. Thank you for you time!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/537817?ContentTypeID=1Tue, 03 Jun 2025 09:28:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb22213c-9f7e-456d-874f-5c446a231ac2Kenneth<p>Hello,</p> <p>I get the impression the programming or recovering might have worked one time.&nbsp;</p> <p>I am suspecting that the reset pin might be pulled low (internally or externally), this cause the chip to be in reset state. Can you try to force the pin high (e.g. connect it to VDD)?</p> <p>If that is not the case, try to run: &quot;nrfjprog --version&quot; just so I can take a look. Also, which pins have you connected between the nRF52840 and the SEGGER j-link in this case? How is the nRF52840 powered here? What SEGGER j-link do you have?&nbsp;</p> <p>Kenneth</p><div style="clear:both;"></div>
