ARM Cortex / Enable Code Read Protection via command-line
« on: October 12, 2016, 07:05:16 am »
I would like to enable the Code Read Protection feature via command-line on NXP NHS3100 ARM microcontrollers.

It looked like this would be possible via the SECURITY command, and the documentation (FlashMagic GUI and Command Line Manual, Rev 2.05) says "for the ARM devices, bit1 = code read protection".

However, all of the following failed:
SECURITY(1) -> Invalid parameters for SECURITY directive
SECURITY(1,0,0) -> Security bit programming failed: invalid command
SECURITY(1,1,1) -> Security bit programming failed: invalid command

Any idea how this could be done?
