WebI have also come across this using an 8080-style interface to an LCD through the FMC on an STM32F7. I thought that it must have something to do with the internal pipeline. I am observing that unless I insert a DSB, instead of seeing the expected five strobes of the write line (4 byte payload, 1 byte command), I see two - one when for each phase ... http://www.hitechglobal.com/FMCModules/FMC+Loopback.htm
