If you're doing a bootloader image, following the instructions on App Note 2757, then you should put it at the bottom of flash (0x0000), and boot low. From reading the App Note, it looks like that's what it assumes.<BR /><BR />Also, make sure you put it at 0x0000, not 0x0100. The image created already has the boot offset built in (same thing if you're putting it high, if you're creating an image that can boot high).<BR /><DIV></DIV></BODY></HTML> Fri, 14 Mar 2008 21:47:57 GMT https://community.nxp.com/t5/Other-NXP-Products/My-MPC5200-board-is-crazy/m-p/201720#M2025 fslaficionado 2008-03-14T21:47:57Z
