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).
