I'm trying to program the UTest area of the MPC5748G MCU.
In particular I'm trying to enable password protection for the JTAG interface, so I'm trying to set the JTAG password field and the life cycle fields in the UTest flash area.
The trouble seems to be that only the JTAG password is written but the life cycle areas aren't - and since UTest is OTP I can only try once per board.
My Lauterbach script and the UTest memory dump are attached.
- any idea why the script doesn't work as expected?
- is there another way (that I missed) to enable password protection for the JTAG interface?
