LPCXpresso_6.1.0_164 often gets into a state in which it keeps saying "Could not connect to core". Cycling power on LPC LINK2, MCU, restarting LPCXpresso, etc, sometimes helps, sometimes not.

What core is it trying to connect and why cannot it connect to it?

When LPCXpresso_6.1.0_164 is in that mode, crt_emu_cm_redlink from LPCXpresso_5.2.4_2122 still works just fine!

Below is the output from LPCXpresso_6.1.0_164's crt_emu_cm_redlink.
