You will know how large your program is and applications usually start at 0x00000000, therefore all space after it is free for other use - like saving parameters or for use as a file system.</P><P>&nbsp;</P><P>More information and all resources are available at <A href="http://www.utasker.com/kirin3.html" rel="nofollow" target="_self">http://www.utasker.com/kirin3.html</A> - see also <A href="http://www.utasker.com/docs/uTasker/uTaskerFileSystem_3.PDF" rel="nofollow" target="_self">http://www.utasker.com/docs/uTasker/uTaskerFileSystem_3.PDF</A></P><P>&nbsp;</P><P>Regards</P><P>&nbsp;</P><P>Mark</P></BODY></HTML> Mon, 03 May 2010 02:25:31 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Writing-and-reading-flash-on-52259/m-p/197149#M8812 mjbcswitzerland 2010-05-03T02:25:31Z Re: Writing and reading flash on 52259 https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Writing-and-reading-flash-on-52259/m-p/197150#M8813 <HTML><HEAD></HEAD><BODY><P>Thank you a lot, Marc!</P></BODY></HTML> Mon, 03 May 2010 07:09:45 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Writing-and-reading-flash-on-52259/m-p/197150#M8813 jejeje 2010-05-03T07:09:45Z
