Hi ,

Does TMS570LS3137 has mechanism to Total Lock Flash Mechanism , so that no write or Erase operation can be performed on Flash .

Write or Erase should be possible only after performing specific unlock sequence using FLASH API F021 . 

Thanks,

    Hello,

    This device includes an advanced JTAG security module (AJSM). The AJSM provides security to the memory content of the device by letting users secure the device after programming. After locked, the JTAG won't be connected to the device without the unlock key.

    The flash itself has a register (FBPROT) to protect the flash bank and sectors from writing.
