Hi,
I am getting practice with your LPC & Kinetis lines, I have prepared the following kit for test -
Want to get HelloWorld up and running, on MCUXpresso v11.0.0 using Window 10. I have a selection of debug tools, how best to proceed?
As for the boards with OpenSDA circuit, you should check if you are affected by a Windows 10 issue (see for example https://mcuoneclipse.com/2018/04/10/recovering-opensda-boards-with-windows-10/ ) and if you need to upgrade the board firmware first.
As for the IDE, keep in mind that 11.4.0 is the current one, so probably best if you use the latest and greatest (you still can keep your 11.0.0, but if using latest SDKs it is better to use the 11.4.0).
I hope this helps,
Erich
