Code Read Protection Feature : Flash Security issue ?

2006-04-03 by croquettegnu

Hi all,

I would like to know what are the limitations of the CRP protection
because this kind of protection is controlled by the onchip bootloader
so by software and I think that it is perhaps less efficient than a
hardware code read protection feature ...

In fact, what are the solutions to access the flash code content even
if CRP is enabled ?

I have seen that ATMEL proposes a flash security bit which disables
the JTAG and prevents from flash access. This protection can not be
suppressed except by erasing the flash which is more secure to my mind
.. Am I worng ?

Thanks in advance
