Other Parts Discussed in Thread: TUSB564
Hi,
I'm trying to enable 4k@60 over 4-lane DP on this EVM. My source and sink can work with 4k@60, if I use type C to HDMI converter. However, EVM can only output 4k@30 from the same source to the same sink. DP cable has been verified to support DP 1.4.
The GPIO (CTL0, CTL1) from TPS65986 to TUSB564 stayed at H and H, meaning it's one port USB 3 + 2Lane DP, and this status does not change.
The event mapped to GPIO 0 (USB 3 Event) and GPIO 1 (DP Mode selection) do not seem to respond accordingly.
Even by putting jumper on these two GPIO to force it into 4 Lane DP, only 4k@30 is the max resolution available.
THanks.
