Guys! The schematic is open and 100% valid! Problems begin when you start modifying the default design. What's the point to ask about the original design if you intend to add/remove things in it? If you route ddr3 wrong then your device will not even start and you'll come to this forum and begin blaming Gerald or other guys who say "it's OK". Stay on the original Gerber files and clone bbb (why would you need it??) without issues 27 Окт 2014 г. 19:35 пользователь "CEinTX" <[email protected]> написал:
