Hi @AbdNxp,

Each application core is equipped with its own Memory Protection Unit (MPU), enabling control over memory access permissions at the core level.

At the system level, memory and peripheral access control is managed by the Extended Resource Domain Controller (XRDC).

The XRDC can be configured using the Resource Management (RM) module provided in the RTD MCAL package.

Additionally, there are RTD example projects available that demonstrate how to configure and use XRDC.

BR, Daniel

Hello Daniel,

I want Code read protection; Suppose I connect the J-link and tried reading the code from the Code flash then the debugger shall not be able to read the application.

will the solution you mentioned in the 1st reply fulfill this requirement?

No, that is something different.

Refer to this thread:

There are links to other documents.
