Hello,

On a Philips LPC2294, when i reset, the internal bootloader write 
FFFFFFFFh at adress 40000128h.

During a debug session with Keil environment, when i press "reset 
button"(which is a micro reset), and i watch memory at adress 
40000128h, memory at this location is changed to FFFFFFFFh.

I just press "reset" and i don't press "go".

I have no code in flash.

I tried to find information in database of this group but 
unsuccessfully.

Let me know if someone has the same problem.

Thanks

Could it be, that the ISP Command handler changed it?
The Documentation write, that the ISP use the memory location
0x40000120-0x400001FF.

Note, that the ISP runs a little bit code before you stop within 
your reset vector, especially if you don't have code in flash.
