Ds80249 P Rev 12 Schematic
: Trace the 3.3V rail powering the SPI Flash storage chip and check the clock line (CLK).
If a major rail is shorted to ground, do not plug in the 12V adapter. Instead, use a laboratory bench power supply to inject the exact nominal voltage of that rail (e.g., inject 3.3V into a shorted 3.3V rail) with a current limit set to 1A or 2A. Apply isopropyl alcohol or use a thermal camera to identify which component instantly boils off the alcohol or glows hot. It is almost always a shorted multi-layer ceramic capacitor (MLCC).

If the DS80249 board is part of a larger system (e.g., a radar display, an industrial CNC machine, or a medical imaging device), contact the , not the PCB vendor. Request the "Engineering Drawing Package" for the specific end-item. Reference the "P Rev 12" specifically.
