Compiler/LAUNCHXL-CC2640R2: Flash readback protection

Tool/software: TI C/C++ Compiler

Hi,

I was wondering if there are any examples or instructions on how to activate flash readback protection. That is, what mechanisms are available in the CC2640R2F to stop readback and decompilation of source code from compiled application images? I believe the CC26XX reference manual cites that the FLASH pages can be marked as execute-only - is there an example of how to do this? Thanks

Hello,

The available customer configuration (CCFG ) options are described in the Device Configuration chapter of the CC26xx TRM (SWCU117). You can disable JTAG (DAP/TAP) access as well as access via the ROM Bootloader via the CCFG to prevent external read/write access to internal memory.

For making these changes, see the ccfg_app_ble.c and the included ccfg.c file.

Best wishes
