OVERVIEW
|
||
|
|
|
||
|
|
- This new lock adds a hardened mode and disables the 0x7f
|
||
|
|
interrupt.
|
||
|
|
|
||
|
|
|
||
|
|
DETAILS
|
||
|
|
|
||
|
|
An example in-field debug payload follows. Any payload is
|
||
|
|
allowed, because the unlock key must be passed to the new
|
||
|
|
interrupt with code 0x41, and this key is only stored in
|
||
|
|
secure memory.
