I see no reference to the PEMicro Cyclone programming tools supporting this but it is possible if the tools are give the capability - you should contact PEMicro to ask specifically.</P><P></P><P>Regards</P><P></P><P>Mark</P></BODY></HTML> Wed, 29 May 2019 00:11:18 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Can-I-write-to-Program-Once-IFR-with-an-external-device/m-p/911765#M53438 mjbcswitzerland 2019-05-29T00:11:18Z Re: Can I write to Program Once IFR with an external device? https://community.nxp.com/t5/Kinetis-Microcontrollers/Can-I-write-to-Program-Once-IFR-with-an-external-device/m-p/911766#M53439 <HTML><HEAD></HEAD><BODY><P>Hi&nbsp;Atilla,</P><P></P><P>Which Kinetis microcontroller are you working with?</P><P></P><P>Regards,<BR />Johnny</P><P>PEMicro Support</P></BODY></HTML> Fri, 14 Jun 2019 20:48:03 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Can-I-write-to-Program-Once-IFR-with-an-external-device/m-p/911766#M53439 johnny_pe 2019-06-14T20:48:03Z Re: Can I write to Program Once IFR with an external device? https://community.nxp.com/t5/Kinetis-Microcontrollers/Can-I-write-to-Program-Once-IFR-with-an-external-device/m-p/911767#M53440 <HTML><HEAD></HEAD><BODY><P>I am using MK64FX512VLL12.
