You can use it from script or batch files are intergrate it into your build.</P><P></P><P>I hope this helps,</P><P>Erich</P></BODY></HTML> Mon, 19 Aug 2019 16:48:29 GMT https://community.nxp.com/t5/CodeWarrior-for-MCU/HCS12-checksum-calculation/m-p/940607#M15168 BlackNight 2019-08-19T16:48:29Z Re: HCS12 checksum calculation https://community.nxp.com/t5/CodeWarrior-for-MCU/HCS12-checksum-calculation/m-p/940608#M15169 <HTML><HEAD></HEAD><BODY><P>Many thanks, I'll try!&nbsp;</P></BODY></HTML> Tue, 20 Aug 2019 06:52:14 GMT https://community.nxp.com/t5/CodeWarrior-for-MCU/HCS12-checksum-calculation/m-p/940608#M15169 fabio_antonucci 2019-08-20T06:52:14Z
