Posted on November 06, 2014 at 09:23i'm using f407zg and try to use USB HS host with internal PHY but found the program never entry interrupt function
my program is modify form host_device_libV2.10-USB_host_example which i tried on eval board successfully
i already defined USE_EMBEDDED_PHY marco and there are init code:
USBH_Init(&USB_OTG_Host,
USB_OTG_HS_CORE_ID,
&USB_Host,
&USBH_MSC_cb,
&USR_Callbacks);
void USB_OTG_BSP_Init(USB_OTG_CORE_HANDLE *pdev)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_GPIOB , ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_15 |
GPIO_Pin_14;
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(GPIOB, &GPIO_InitStructure);
GPIO_PinAFConfig(GPIOB,GPIO_PinSource15,GPIO_AF_OTG2_FS) ;
GPIO_PinAFConfig(GPIOB,GPIO_PinSource14,GPIO_AF_OTG2_FS) ;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_OTG_HS, ENABLE) ;
}
so any advice?
