Overview of the Diagram

  • DDR4 routing: Fly-by topology with termination resistors (22Ω) placed just before the CPU. All lanes are length-matched within 5 mils – visible in the board diagram trace callouts.
  • eMMC interface: 8-bit data bus connected directly to the SDHC2 controller. No level shifting needed (1.8V signaling).
  • Debug port: A 10-pin Tag-Connect footprint (not populated) keyed as JTAG. The diagram labels pins: TCK, TMS, TDI, TDO, SRST, and 3.3V.
