1.2 Locking

The F021 Flash API supports programming the customer OTP of which the first 128 bits and their associated ECC are the AJSM Visible Unlock Code at address 0xF0000000. TI and third party tools support programming this location either integrated into the application or standalone. Standalone programming of the AJSM is recommended for production flows that need to perform system level testing.

Once a device is locked, the ICEPICK and AJSM will be the only visible tap (Test Access Port); the scan chain will still be available and discoverable as a length of 6 to allow for easy identification that the device is functional. When the AJSM is locked, the typical emulator response will be no communication. To differentiate JTAG communication issue from a locked AJSM, perform a scan chain check or read the JTAG ID.
