8.1.11 Security

The devices support high levels of security to protect the user firmware from being reverse-engineered. The security features a 128-bit password (hardcoded for 16 wait states), which the user programs into the flash. One code security module (CSM) is used to protect the flash/OTP and the L0/L1 SARAM blocks. The security feature prevents unauthorized users from examining the memory contents through the JTAG port, or trying to boot-load some undesirable software that would export the secure memory contents. To enable access to the secure blocks, the user must write the correct 128-bit KEY value that matches the value stored in the password locations within the Flash.

In addition to the CSM, the debug code security logic (ECSL) has been implemented to prevent unauthorized users from stepping through secure code. Any code or data access to CSM secure memory while the debug probe is connected will trip the ECSL and break the debug probe connection. To allow debug of secure code, while maintaining the CSM protection against secure memory reads, the user must write the correct value into the lower 64 bits of the KEY register (KEY0 – KEY3), which matches the value stored in the lower 64 bits of the password locations within the flash. Dummy reads of all 128 bits of the password in the flash must still be performed. If the lower 64 bits of the password locations (PWL0 – PWL3) are all ones (unprogrammed), then the KEY value does not need to match. During debug of secure code, operations like single-stepping is possible. However, the actual contents of the secure memory cannot be seen in the CCS window.

When power is applied to a secure device that is connected to a JTAG debug probe, the CPU will start executing and may execute an instruction that performs an access to a protected area. If this happens, the ECSL will trip and cause the JTAG circuitry to be deactivated. Under this condition, a host (such as a computer running CCS or flash programming software) would not be able to establish connection with the device.

The solution is to use the Wait boot option. In this mode, the device loops around a software breakpoint to allow a debug probe to be connected without tripping security. These devices do not support a hardware wait-in-reset mode.

Note:
  • When the code-security passwords are programmed, all addresses from 0x3F 7F80 to 0x3F 7FF5 cannot be used as program code or data. These locations must be programmed to 0x0000.
  • If reprogramming of a secure device via JTAG may be needed in future, it is important to design the board in such a way that the device could be put in Wait boot mode upon power-up (when reprogramming is warranted). Otherwise, ECSL may deactivate the JTAG circuitry and prevent connection to the device, as mentioned earlier. If reconfiguring the device for Wait boot mode in the field is not practical, some mechanism must be implemented in the firmware to detect when a firmware update is warranted. Code could then branch to the desired bootloader in the bootROM. It could also branch to the Wait bootmode, at which point the JTAG debug probe could be connected, device unsecured and programming accomplished through JTAG itself.
  • If the code security feature is not used, addresses 0x3F 7F80 to 0x3F 7FEF may be used for code or data. Addresses 0x3F 7FF0 to 0x3F 7FF5 are reserved for data and should not contain program code.
  • The 128-bit password (at 0x3F 7FF8 to 0x3F 7FFF) must not be programmed to zeros. Doing so would permanently lock the device.
