I have annoying problem with a MC9S08AW60 microcontroller. When I try to store some variables (11 bytes) in a flash reserved zone (reserved zone 0x1860 through 0x1A5F but no more than 0x186A used), I observe a malfunctioning program, sometime freezes etc.<BR />I think that's code corruption problem, Can anyone help me? <BR />I'm not sure If my prm file is correctly configured (berore read&nbsp; AN3730 and AN2616 but they not detailled information about PRM file configuration), after take a look into MAP file I state that tehres no code in reserved zone, but the program still fails... I'm bit desesperate.<BR />flash.c, prm file and map file included here</P><P style="min- padding: 0px;">&nbsp;</P><P>Thanks in advance. </P><P><STRONG>Original Attachment has been moved to: <A _jive_internal="true" href="https://community.nxp.com/docs/DOC-337716">Project.prm.zip</A></STRONG></P><P><STRONG>Original Attachment has been moved to: <A _jive_internal="true" href="https://community.nxp.com/docs/DOC-337716">flash.c.zip</A></STRONG></P><P><STRONG>Original Attachment has been moved to: <A _jive_internal="true" href="https://community.nxp.com/docs/DOC-337716">Project.map.zip</A></STRONG></P></BODY></HTML> Mon, 07 Oct 2013 16:24:48 GMT raulalvarez 2013-10-07T16:24:48Z MC9S08AW60 Code execution corruption after Writing in Flash / EEPROM routine https://community.nxp.com/t5/8-bit-Microcontrollers/MC9S08AW60-Code-execution-corruption-after-Writing-in-Flash/m-p/266925#M20058 <HTML><HEAD></HEAD><BODY><P>Hi to all,.</P><P style="min- padding: 0px;">&nbsp;</P><P>Im new on this forum.
