1.1 AJSM Key Generation

The AJSM key is stored in memory that only allows changing 1s to 0s. TI ships the devices programmed with the 128-bit visible unlock code at address 0xF00000000 and your ECC.

TI Visible Unlock Code (TMS570 [Big Endian] ECC) 0xF00000000: 0xEFFDFFFF 0xFFFFFFFF 0xFFFDFFFE 0xFFEFFFFF ECC: 0xFFFF

This code is mainly 1s to allow for a custom key effective to 123 bits. The ECC is calculated based on the device's endianness. Hercules TMS570 devices are big endian, their visible unlock code ECC has been designed to be all 1s so any key can be selected. Hercules RM devices are little endian, their visible unlock code ECC will be 0xEDCO. Because the ECC is not all 1s, some custom unlock code values will not be possible. Read the value at 0xF000000 for your devices specific AJSM unlock code and 0xF0040000 for the ECC.
