Part Number: TMS570LS1227
I cannot find any information how to protect the flash memory from reading through the jtag interface to prevent third parties to make illegal copies of the electronics. Is there additional documentation outside the user manual available? Also how do you enable this protection with CCS?
TMS570LS1227 includes Advanced JTAG Security Module (AJSM). which provides maximum security to the device’s memory content by allowing users to secure the device after programming.
Refer to Section 6.21.6 Advanced JTAG Security Module in Datasheet.

In reply to Miro:
thank you, I was looking for AJSM but in the user manual not in the data sheet :-)
Would you know if there is a way of writing and unlocking this register in CCS? Or are there any command line programming tools available (preferred option)?
