自己代码写的有问题吧  你先关注下 LINE：1636
void LCD_FunConfig(void)
{

        //MainLCD = &LCD_func_OTM4001;
        PROF_driver_lcd_init();
        #ifdef DUAL_LCD
                //SubLCD = &LCD_func_HD66791;
        #endif
}
在看  PROF_driver_lcd_init();  在 LINE183

kal_uint16 PROF_driver_lcd_init(void)
{
        extern LCD_Funcs LCD_func_OTM4001;
        extern LCD_Funcs LCD_func_ILI9486;
          prog_check_lcd_id = PROF_LCD_CheckLcdID();
        if(prog_check_lcd_id == 0x5420)
        {
                MainLCD = &LCD_func_OTM4001;
        }
        else
        {
              MainLCD = &LCD_func_ILI9486;
        }       

}       

难道每次不是走的不是 void LCD_Init_OTM4001(kal_uint32 bkground, void **buf_addr)
{
        // Enhance LCD I/F driving current.
#if defined(MT6238)
        *((volatile unsigned short *) 0x80010700) |= 0xE0E0;
#endif

你的意思是ID读不对是不是？

ID都能读出来，但是一直走的是ILI9486

自己代码写的有问题吧  你先关注下 LINE：1636

此套兼容我在5310上是可以兼容的，现在现象是一直走的 ILI9486

你把lcd。obj 删除在编译下 试试

new了也不行

void LCD_FunConfig(void)
1.你打印一下这个函数跑了几次。
2.你在你自己加的函数里只读ID，返回后在LCD_FunConfig判断。
