Hi,

We are developing products with ADV7627.

The OSD (with internal flash memory) is generated by Blimp 3.9 SP2.

 

Have you seen the following phenomenon when switching between Freerun "ON" and Freerun "OFF" is repeated?

It occurs when we repeat about 500 to 5000 times.

 

Once this phenomenon occurred, it was not drawn correctly unless it was reset by OSD_RST (IO: 0xfe [4]) or MAIN_RST (IO: 0xff [7]).

 

Could you tell me how to solve it?

 

1st. FreerunON (VIC=16 : 1920x1080@60Hz)....Good

 

2nd. FreerunOFF (3840x2160@30Hz)...Good

 

3rd. FreerunON (VIC=16 : 1920x1080@60Hz)....Good

           :

about 600th. FreerunON (VIC=16 : 1920x1080@60Hz)....No Good!!

 

about 601th. FreerunOFF (3840x2160@30Hz)...No Good!!

 

In other cases, the icon disappeared or the message disappeared.

 

FreerunOFF (3840x2160@30Hz)...No Good!!

FreerunOFF (3840x2160@30Hz)...No Good!!

 

When the phenomenon occurs, when the switching between Freerun ON and Freerun OFF is repeated, the drawing state becomes more and more worse.

 

Best regards,
