Hello,
I found a solution:
In the LCD.C:
    static void LCD_7637_Controller( void )
        {
        extern void starting_delay ( long unsigned  );
        /** Apply hardware reset **/
        LCD_CtrlLinesWrite( GPIOx_CTRL_LCD, CtrlPin_RST, Bit_SET );    /* RST = 1  */
        LCD_CtrlLinesWrite( GPIOx_CTRL_LCD, CtrlPin_RST, Bit_RESET );  /* RST = 0  */
        starting_delay( 0x3000 ); // Changed from 0x500
        LCD_CtrlLinesWrite( GPIOx_CTRL_LCD, CtrlPin_RST, Bit_SET );    /* RST = 1  */
        starting_delay( 0x3000 ); // Changed from 0x500
Then it can run witout the delay in main:
    /* The LCD monitor is not always properly initialized:
    the starting delay allows to wait for a longer power up.                */
    #ifdef PRIMER2
    delayms(100);
    #else
    starting_delay( 100 ); // KJ - Changed from 0x10000
    #endif
Then my display in primer1 is not mirrored any more
