3 Enabling JTAGLOCK

Enabling the JTAGLOCK feature is a two step process:

  1. Program a 128-bit JTAG password (Z1OTP_JTAGPSWDHx/Z1OTP_JTAGPSWDLx).
  2. Enable the JTAGLOCK module (JLM) by programming Z1OTP_JLM_ENABLE.

NOTE

When you want to change the Z1OTP_JTAGPSWDLx value, select a new Zone Select Block by changing the Z1OTP_LINKPOINTERx value and programming a new value for Z1OTP_JTAGPSWDLx.

Just like the programming of any other security configuration, the JTAGLOCK settings can be programmed by the CCS flash plug-in GUI or by incorporating these values in the .out file itself.
