Hello @Gvinity ,
Thanks for considering our products.
Can I use NXP development tools under Linux?
---> Yes. I recommend that you use MCUXpresso. It is compatible with Linux.

The SDK for LPC11U6 is in LPCOpen and it can be used in MCUXpresso. For the specific method, please refer to the link below.
