Hi
I'm not sure what broke but neither lpc40xx_ea_ram
nor lpc40xx_ea_rom build.
I cannot reproduce this problem. Which error do you get?
Hmmm... I neglected to mention that I am using gcc master also. Sorry.
One of the configure conftest.c probes is failing with an object
architecture
variant mismatch.

With gcc 8.0 trying to head to a freeze, I wonder if you could take a

ARM changed the floating point machine options in GCC 8. I guess we have
to change all machine flags once we start to use GCC 8.
