MCUXpresso IDE V11.2.1

I have started the semester and labs using the MCUXpresso IDE V11.2.0 which has been available from July this year. The past week I received the notification that the update V11.2.1 is available: time to check it out….

The version number change from V11.2.0 to V11.2.1 indicates a minor update and bug fix. As before it is possible to run multiple IDEs in parallel by default, so I can keep using the previous versions and don’t have to make a switch for older projects.

I tried the new version with a bunch of new projects, and this worked fine. On a side note: it is still compatible with Processor Expert projects which is great!

The release notes of the update shows that it includes mainly support for new devices and bug fixes. The compiler/build tools are the same as in 10.2.0 too:

arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]

The dark theme support received several visual updates, improving the readability of several plugins.

Update: for the Dark theme, make sure you set your host (Windows) to ‘Dark’ too:

That way Eclipse follows the theme for things like scrollbars too.

What are new and updated are the P&E and SEGGER debug libraries, featuring the latest versions. As a new feature there is the ability to auto-debug multicore slave projects for LinkServer connections. This feature can be disabled in the preferences:

Disable Auto-debug slave projects for multicore projects


All in all: the new version comes with a series of smaller updates. I do not see a critical need for an update, but it shows a continuous improvement. For users of the ‘dark theme’, the upgrade is for sure very welcome. Very welcome is that the P&E and SEGGER debug probe support has been updated. Talking about debug probe support: the IDE supports a new MCU-Link debug probe for LPC, Kinetis and i.MX RT. More on this later when I find out more …

Happy Xpressing 🙂
