Set defines in .h file or initialization. Also you can change codes for your own.

The main program start is $8005000.<br /> For the F2/F4 CPUs the 16KB flash pages are at $8008000 and $800C000, main program start at $80010000. </p> http://forums.leaflabs.com/topic.php?id=196&page=2#post-7928 Sat, 28 Jan 2012 12:50:27 +0000 x893 7928@http://forums.leaflabs.com/ <p>May be offline somtimes </p> http://forums.leaflabs.com/topic.php?id=196&page=2#post-7926 Sat, 28 Jan 2012 09:11:29 +0000 djk 7926@http://forums.leaflabs.com/ <p><a href="http://akb77.com/g/stm32/maple-eeprom-emulation-library/" rel="nofollow">http://akb77.com/g/stm32/maple-eeprom-emulation-library/</a><br /> appears to be a dead link now?<br /> any help is appreciated...also i'd love to find a memory map definition such that i can be sure i'm not writing over my codespace/bootspace.
