Other Parts Discussed in Thread: TPS65988DK
I am debugging TPS65988DK EVM.
When I connect the EVM with laptop and monitor as the picture shows using portB.
1. But the HPD_LED will not turn on and the video signal transmission failed. Only MXCTL1 light will turn on.
I use the tool to analysis the negotiation. It could enter DP mode.
2. But Keep attention, and the HPD status keeps changing between 0 and 1.
It is the boot default settings. I also tried TPS65988D EVM, the same.
Can you help to analysis the potential reason?
3.Besides, in the TPS65988DK EVM, it seems the port A is disabled by software of hardware. Is it right? Because whenever I connect anything, it has no response.
