5.3 Secure
platform
limitation
The STMicroelectronics platform provides the following code protection means.
RDP
: ReadOut Protection
Prevents Flash Memory access through the JTAG for ALL Flash memory.
PcROP
: Proprietary Code ReadOut Protection
Prevents read access of configurable Flash memory areas performed by the CPU execution
of malicious third-party code (Trojan Horse).
WRP
: Prevents accidental or malicious write/erase operations.
For further details please refer to the reference manual or section
Training L4

STMicroelectronics website
The next sections provide additional details on the expected behavior of the secure
applications.
5.3.1 RDP
•
Level 0: No Protection.
This is the factory default mode allowing all accesses.
•
Level 1: Read Protection.
Any access to Flash or protection extension region generates a system hard-fault
which blocks all code execution until the next power-on reset. A simple reset does re-
enable code execution; power must be switched off and on so that power-on reset
enables code execution. The restriction depends on the STM32 Series as described in
.
