usbh_stm32f40x.c __XYNERGY

Hi,

I am having problems getting USB host running.

Platform: STM32F407

I see in usbh_stm32f40x.c a conditional __XYNERGY. What is this conditional for?
If it is not defined, then PH5 is used for something (not sure what, not sure if it is even important for just a usb host application).
PH5 is a non-existing pin on my platform!

Should I define __XYNERGY or not?

Kind regards,
Ruud

I found some settings that work.

      GPIO_InitTypeDef GPIO_InitStructure;
      RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE); //Comment and check....

      /* Configure SOF VBUS ID DM DP Pins */
      GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9 | GPIO_Pin_11 | GPIO_Pin_12;
      GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
      GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
      GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
      GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
      GPIO_Init(GPIOA, &GPIO_InitStructure);
      //GPIO_PinAFConfig(GPIOA,GPIO_PinSource8,GPIO_AF_OTG1_FS) ;
      GPIO_PinAFConfig(GPIOA, GPIO_PinSource9, GPIO_AF_OTG1_FS);
      GPIO_PinAFConfig(GPIOA, GPIO_PinSource11, GPIO_AF_OTG1_FS);
      GPIO_PinAFConfig(GPIOA, GPIO_PinSource12, GPIO_AF_OTG1_FS);
      /* this for ID line debug */
      GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
      GPIO_InitStructure.GPIO_OType = GPIO_OType_OD;
      GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;
      GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
      GPIO_Init(GPIOA, &GPIO_InitStructure);
      GPIO_PinAFConfig(GPIOA, GPIO_PinSource10, GPIO_AF_OTG1_FS);
      RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
      RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_OTG_FS, ENABLE);

But now I have another problem (see my new thread)...
