The code space is located at E00000... for the eval boards from Freescale.<BR /><BR />Code Flasher allows you to select the 5485evb(boot), which defaults to FF800000 or the code space default is E0000000.<BR /><BR />I suggest you try both FF800000 or FFE00000. Also look at your boot rom hw cfg pins.</BODY></HTML> Sun, 11 Feb 2007 16:26:02 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Flash-programming-with-coldfire/m-p/144998#M3027 Marreshe 2007-02-11T16:26:02Z
