Part Number:MSP430F5437A
Hello,
This is about MSP430F5437A security.
I have more questions related to https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/814820. There were answers about BSL password as follows:
- If JTAG is disabled, the only way to access the MCU memory is by providing the correct BSL password. If an incorrect BSL password is given, the FRAM memory is erased
Further questions are:
- After MCU fully erased by providing the wrong password, could the MCU be reprogrammed with new firmware and the new password?
- In the case the BSL password is leaked, the firmware in MCU could be readout and could be reprogrammed with the modified firmware, correct?
- Can BSL password be implemented as unique for each device/MCU?
Thanks, HJ
