Flash content protection for LPC824

In this article, I would like to discuss about evaluation of LPC824 low cost 32-bit ARM Cortex-M0 microcontroller using OM13071 LPCXpresso824-MAX Development board. LPC824M201JHI33 is used in the board. Its size is only 5 x 5 x 0.85 mm in HVQFN package.

In order to evaluate it, MCUXpresso Integrated Development Environment (IDE) is downloaded and installed. Other tools for it can be found at this link . After launching MCUXpresso and assigning a workspace folder, example projects can be imported by clicking Quick Start Panel (near bottom left corner) -> Import projects from file system ... -> Browse LPC open resources as shown in the following figure.

Protecting Flash Memory of a Fujitsu MCU

I had a requirement to protect flash memory of Fujitsu MB95F128JB MCU but I could not find any satisfactory hardware/software tool to protect it. Later, I conceived an idea to hack its .mhx file. After adding the following line before the last line of the .mhx file, it had been protected.
