Bootloader USB MSD on MCF52254

Hi !

I am trying to use the Bootloader USB MSD v3_2 (USB Bootloader V2 Blinks LED1 project) on a custom board with a MCF52254.

I just changed three things :

- the LED pin (Port TC0 to Port TC2)

- the button or jumper pin (Port NQ5 to Port AN5)

- remove debug (no debug on MCF52254, Port DD doesn't exist)

I have the following problem :

If I use my debbuger (AxBDM CF -> a TLBCF : http://www.axman.com/node/303), everything works good !

If I program the MCF52254, nothing happens !

I am sure that it is a problem with the .lcf file.

I think when I program, the reset vector is false

If somebody can help me...

Thanks by advance !

Thomas
