I'm using Vivado 2018.3.
Now I've faced one question that the SMPTE UHD-SDI Transmitter Subsystem could not run properly at 12G mode after it was configured without axi-lite interface.
I configured the sdi_tx_ctrl[6:4] to 12G tx_mode. The wave from the TX_Bridge showed that it worked not right.
The sdi_ds_in_ds1 to sdi_ds_in_ds8 always stuck at 0 state.
If I set the sdi_tx_ctrl[6:4] to other value as 3'b000, 3'b001, 3'b010. It could work fine. But it could not work right when the sdi_tx_ctrl[6:4] value was set to 3'b100 or 3'b101.
Anybody know that how to configure the sdi_tx_ctrl port to let the IP run properly at 12G mode? May be it need some more point to set?
Thanks for your help.
