USB bootloader AN10759

Frank de Jonge

I'm trying to run the USB secondary bootloader(NXP-AN10759) on an MCB2300 (v3) using the evaluation version of Keil (MDK-Lite v 4.70)
It doesn't work. writing a simple piece of code and compiling it does...so, what am I missing.
Is it possible to compile the code from this application note on the Lite version at all?
Maybe someone can provide me with a verified .hex file for this board, so I can exclude some parts of the process.(unfortunately I have no Jtag debugger that fits Keil)

Thanks

    I can only try..

    Since this code was written for the MCB2300, I assume it should be able to work on this board.
    I can program the board with the "memory.hex" file generated by MDK-Lite v 4.70, but nothing seems to run. I also tried to bypass some initial code by always jumping to the isp code. No response there.
    So my question is:
    Can I use the evaluation version to compile this code at all?
    (code also seems faily big(>0x4000bytes) since the bootloader should only occupy the first 2 sections of the internal Flash)

    If so, anything I should check to get me going?
