I 'm new in writing a bootloader for freescale 12xet256 microcontroller,I  get from the newer application note AN4258 Serial Bootloader for S12(X) Microcontrollers Based on 180 nm Technology



I meet two questions:


first:i use demo AN4258 ,but dont dowmload program via TBDML,the computer show "Error while writing to FD00..FF00" 

second  : i replace TBDML, use USB Multilink Universal FX ,unfortunately   codeworrior5.1 can't recognise the tool,

            show "undected Disconnect/connect USB cable. click Refresh list"



please help me,thank you!
