https://devzone.nordicsemi.com/f/nordic-q-a/32777/the-chipset-bmd-300-is-not-being-detected-in-nrfgo-studioHi All, the I/O mapping is correct as per the Ref Eval schematics. We are using a J-Link programmer to program it. The IC is not being detected in NRFgo studio. Can anybody help me out with this? Thanks.en-USTelligent Community 13Wed, 18 Apr 2018 11:17:13 GMThttps://devzone.nordicsemi.com/thread/128780?ContentTypeID=1Wed, 18 Apr 2018 11:17:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75128b86-15a1-48d5-a4c7-db6b9b2b78bcMani<p>We are using j-tag segger for programming, supply voltage on board is 3.3V and we are able to read the same in jlink.exe also.</p> <p>But still, the device is not detected in nRFgo studio.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/126125?ContentTypeID=1Tue, 27 Mar 2018 13:06:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:242ff79a-6466-46c6-8ef8-7857a6c7980fVidar Berg<p>Hi,</p> <p>Just to confirm, did you select the nRFx Programming entry, and is this the message you got?:</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-423f57f0dcbb4d40a9cf753cb454f393/Capture.PNG" alt=" " /></p> <p>Follow up questions:</p> <ul> <li>Which Jlink programmer are you using?</li> <li>What is the supply voltage on the board?</li> <li>Does the programmer detect the correct target voltage?
