Sorry for my mistake,

Actually the stop and start work fine with the Scaler Core. My problem is with others registers. This is how I use my function :

# define ALT_VIP_SCALER_II_OUTPUT_WIDTH_REG 3

ALT_VIP_SCALER_II_WRDATA (ALT_VIP_CL_SCL_LCD_DF_BASE , ALT_VIP_SCALER_II_OUTPUT_WIDTH_REG , 600 );

Output Width register is a readable and writable register.

Anyway, thank you for your help, I'll follow your advice by opening a ticket.

If you have others suggestion, don't hesitate ;)
