I have some problems with the CP free run function.
First I executed the "5.3a HDMI In (CP ENABLED)YPrPb_Out_Audio 48Khz PCM I2S audio (up to 225Mhz only)" after reset. If there's a valid input signal on HDMI port A, and I forced the free run (CP_FORCE_FREERUN), the blue screen appeared on the output. The other settings were:
- HDMI_FRUN_MODE = 0
- HDMI_FRUN_EN = 1
- CP_DEF_COL_MAN_VAL = 0
- DIS_AUTO_PARAM_BUFF = 1
- All autographic registers were filled 0
The changing of the output format with the VID_STD and PRIM_MODE parameters also worked correctly. If I turned down the input signal, the output free run signal disappeared and I couldn't get it back by any operation.
How can I output a free run screen if there isn't any input signal?
