3.2 Debugging the EVM

The following checks can help resolve issues when connecting the TPS65987DDKEVM to another EVM or USB Type-C device and no status LEDs are on:

  • Make sure that a firmware image is loaded on the TPS65987DDKEVM, using the TPS6598x configuration tool (GUI).
  • Make sure the CC lines are toggling for dual-role port functionality.
  • Make sure the following system supplies:
    • P3V3 = 3.3V
    • P5V0 = 5V
    • Barrel jack / SYS_PWR = 20V (when plugged in).
    • VAR_DCDC = 5V (when barrel jack is plugged in without a USB Type-C attached cable or device).
    • VBUS = 5V, 9V, 15V, or 20V (when USB Type-C port is attached to another EVM or device).
