Hi ! Regarding the issue of the addresses put into the HEX files for the config word for the 10F's... FWIW, I just built my "beta" of my 10F application using MPLAB 6.60, relocatable code using the builtin 10F202.LKR file as-supplied, and using Olins data directive instead of __CONFIG. Now, I'm no expert in reading HEX files (they are just "temp" files for me :-) ), so could anyone see if the adresses in the HEX file below are correct ? And, Olin, are you sying that the following entry in the 10F202.LKR file is incorrect ? CODEPAGE NAME=.config START=0xFFF END=0xFFF PROTECTED That is, it should be "START=0x3FF END=0x3FF" !? All four LKR files (200/202/204/206) have "0xFFF" at that line. Best Regards, and thanks, Jan-Erik. My HEX file : :020000040000FA :100000002500000B010C280008022A000B060A0A32 :1000100006040B0A0605020C2509EA020B0A09026E :100020002A000B06150A0605160A0604020C250905 :10003000EA02160AA802E902040A0B06210A0604CB :10004000220A0605000800000008210061020102E2 :060050004307270A000827 :040056000008000896 :100200000E0C0600C20C02006C0C29000B05020942 :1002100023096C0C29000B0402096C0C29000B0546 :10022000020923096C0C29000B0402096C0C29003B :100230000B05020923096C0C29000B040209040BAD :02024000200B91 :021FFE00EB0FE7 :00000001FF _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
