topic Fixing EntryPoint in S12 / MagniV Microcontrollers https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Fixing-EntryPoint/m-p/139849#M2967 <HTML><HEAD></HEAD><BODY>Hi<BR />Does anybody know how to fix the _EntryPoint function generated by Codewarrior to a specific address. I have written a bootloader for the MC9S12NE64 and need to be able to fix the application startup point. At the moment I am using a #pragma and placing it in a block of code but am not convinced that every compilation will result in _EntryPoint being at the same address. Any suggestions??<BR />Thanks<BR />Morag</BODY></HTML> Wed, 13 Dec 2006 20:52:50 GMT morag 2006-12-13T20:52:50Z Fixing EntryPoint https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Fixing-EntryPoint/m-p/139849#M2967 <HTML><HEAD></HEAD><BODY>Hi<BR />Does anybody know how to fix the _EntryPoint function generated by Codewarrior to a specific address.
