stm32h7 with 32-bit sdram interface (256 MBit)
** NOTE! ** This routing is actually bad, mmkay... I made a big blooper pin swapping the data lines. They cross the byte lane boundary... I've made maybe actually working version of this and that should be public on the EasyEDA. https://youtu.be/BIjSuwN3AWM The mistake was that some data lines crossed over the byte lanes, with this there is ONLY 32-bit access, no byte or half word... :) stm32h7 pcb with 32-bit sdram interface (256 MBit)
