Thank you Pavel alot , it really helps alot ;
now I can see the TWO host in start mode
but I still have problem in File fatfs
It return a disck error when i work with the two usb ; but when i test one host seperattly with its disckio no problems .
maybe a mistake in my settings here ?
USBH_StatusTypeDef USBH_LL_Init(USBH_HandleTypeDef *phost)
{
/* Set the LL driver parameters */
if(phost== &hUSB_Host)
{
hhcd.Instance = USB_OTG_FS;
hhcd.Init.Host_channels = 11;
hhcd.Init.dma_enable = 0;
hhcd.Init.low_power_enable = 0;
hhcd.Init.phy_itface = HCD_PHY_EMBEDDED;
hhcd.Init.Sof_enable = 0;
hhcd.Init.speed = HCD_SPEED_FULL;
/* Link the driver to the stack */
hhcd.pData = phost;
phost->pData = &hhcd;
/*Initialize the LL Driver */
HAL_HCD_Init(&hhcd);
USBH_LL_SetTimer(phost, HAL_HCD_GetCurrentFrame(&hhcd));
return USBH_OK;
}
//---
if(phost== &hUSB_Host1)
{
/*Set LL Driver parameters */
hhcd1.Instance = USB_OTG_HS;
hhcd1.Init.Host_channels = 11;
hhcd1.Init.dma_enable = 1;
hhcd1.Init.low_power_enable = 0;
hhcd1.Init.phy_itface = HCD_PHY_EMBEDDED;
hhcd1.Init.Sof_enable = 0;
hhcd1.Init.speed = HCD_SPEED_HIGH;
hhcd1.Init.use_external_vbus = 1;
/* Link The driver to the stack */
hhcd1.pData = phost;
phost->pData = &hhcd1;
/*Initialize LL Driver */
if (HAL_HCD_Init(&hhcd1) != HAL_OK)
{
return USBH_FAIL;
}
USBH_LL_SetTimer (phost, HAL_HCD_GetCurrentFrame(&hhcd1));
return USBH_OK;
}
return USBH_OK;
}
should i use seperate channels ? both now 11 .
Thank you alot
