Lpc2000

Just a few thoughts:
I have a very nice programm and i know some people want to take a look
how it works. So i put it in my LPC2148 with bootloader > V1.61 and
put these special bytes at this special location (0x000001Fc =
0x87654321) and then it should be secure. ok. that's theory. So how
secure is it now? Is Jtag closed? Can i read flash via JTAG? Can i
still update the bootloader (it says that the flash will not be harmed
if i update the bootloader)? If there is still any way to update the
bootloader then ... i think i don't need to tell more... so if i write
this 0x87654321 to 0x1FC is updating of the bootloader still possible?
I only got a LPC2106 over here and this one has no code protection at
all. It would be nice to know before i start using this very very nice
LPC2148-processor. I really like it, but i need flash-security at a
very high level.
