I designed my own board with PN7462. It based on development kit OM27462CDK. My schematic is in attachment. I have som FW to EVB when board is login into windows as COM port. this same FW I flashed to my board. When I tried to turn on RF field i gave erro message that RF field cannot be turn on. But on oscilloscope I measured that field is on. In my schematic if i desoldered B4 than i dont have problem but of course when i tried measure field was off. </P></BODY></HTML> Wed, 31 Jul 2019 06:38:54 GMT https://community.nxp.com/t5/NFC/PN7462-RF-field-on-problem/m-p/932568#M5756 cepec 2019-07-31T06:38:54Z Re: PN7462 RF field on problem https://community.nxp.com/t5/NFC/PN7462-RF-field-on-problem/m-p/932569#M5757 <HTML><HEAD></HEAD><BODY><P>Hi Lukas,</P><P></P><P>Looks like the connection of TVDD_OUT is different from the EVB, Please refer to the following for details.</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_1.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/84575i4F1DC2D6C71CCD40/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_1.png" alt="pastedImage_1.png" /></span></P><P>Please try to remove B3 on your board.</P><P></P><P>Hope that helps,</P><P></P><P>Have a great day,<BR />Kan</P><P></P><P>-------------------------------------------------------------------------------<BR />Note:<BR />- If this post answers your question, please click the "Mark Correct" button.
