According to MSP432P4111 Launchpad User's guide (Revised Jan 2019: http://www.ti.com/lit/ug/slau747b/slau747b.pdf)
Page 22: "Your device is also supported by the Energia IDE"
However, I see no mention of the P4111 in the board manager 1.8.7.E21 (Win10) ...only the P401R and the E401Y.
Is this board actually supported? ...perhaps by selecting the P401???
OK. I'll see what I can do to help. I just bought one, so we'll see how it goes!
I see 5.25 has the P4111 as an unimplemented variant. Where can I find the source for the board files in github? I tried this location but its 5.6.1:
