The goal is for it to read the temperature from its sensor and expose it as a parameter in a URL, which will be published on the NFC tag.</P><P>I successfully uploaded the code using J-Link in MCUXpresso, and everything works perfectly. However, when I upload the code using the NHS31xx NFC Program Loader, the code uploads fine, but my phone no longer reads the tag unless the tag is externally powered.</P><P>What configuration do I need to enable the NFC tag to be powered through NFC after uploading the code via NFC Program Loader?</P><P>Any help would be greatly appreciated!</P> Thu, 03 Oct 2024 11:01:25 GMT https://community.nxp.com/t5/Wireless-MCU/One-time-NFC-program-downloader/m-p/1966346#M19018 gpol2003 2024-10-03T11:01:25Z https://community.nxp.com/t5/Wireless-MCU/One-time-NFC-program-downloader/m-p/1966626#M19020 <P lang="en-US">Hello, my name is Fabian, I've been assigned to support your case.</P> <P lang="en-US">Thank you for your interest in our products</P> <P lang="en-US">The NHS3100 has a VNFC which is a power input selector that is in charge of selecting the switch that fulfills the PMU requirements.</P> <P lang="en-US">For further information please take a look at section <A href="https://www.nxp.com/docs/en/data-sheet/NHS3100.pdf" target="_self">8.4.1 System power architecture</A> where the VNFC and NFC Power Switch (PSWNFC) are explained and shown in a diagram.</P> <P lang="en-US">Please also take a look at <STRONG>UM10876</STRONG> 5.4 System power architecture where the power configurations and, sequences are also described.</P> Thu, 03 Oct 2024 22:22:03 GMT https://community.nxp.com/t5/Wireless-MCU/One-time-NFC-program-downloader/m-p/1966626#M19020 Fabian_R 2024-10-03T22:22:03Z
