ST32F429 two usb host problem

[ASSAAD.ASSAAD]

Hello All and thank you in advanced

I have a pplication that we use two host usb connected to flash disks , one uses PORTA usb and other uses PORT B usb .

i have test every usb seperatlly with file system after modifie usb_diskio and all work with no problems

but when I use together and same time only one host work !

I have been debuging and testing for 4 days and no result , could you guide me to find the problem please .

if((FATFS_LinkDriver(&USBH_Driver, USBDISKPath) == 0) && (FATFS_LinkDriver(&USBH_Driver1, USBDISKPath_1) == 0))

 {

//  /*##-2- Init Host Library ################################################*/

//  USBH_Init(&hUSB_Host, USBH_UserProcess, 0);

//  

//  /*##-3- Add Supported Class ##############################################*/

//  USBH_RegisterClass(&hUSB_Host, USBH_MSC_CLASS);

//  

//  /*##-4- Start Host Process ###############################################*/

//  USBH_Start(&hUSB_Host);

/*##-2- Init Host Library ################################################*/

  USBH_Init(&hUSB_Host1, USBH_UserProcess, 0);

  

  /*##-3- Add Supported Class ##############################################*/

  USBH_RegisterClass(&hUSB_Host1, USBH_MSC_CLASS);

  

  /*##-4- Start Host Process ###############################################*/

  USBH_Start(&hUSB_Host1);

}

while(1)

{

 USBH_Process(&hUSB_Host1);

    USBH_Process(&hUSB_Host);

}

//-------------------------

only host hUSB_Host1 work and the hUSB_Host stile ideal state

what could be the problem here please ?

Thank you

I post here

static void USBH_UserProcess(USBH_HandleTypeDef *phost, uint8_t id)

{  

if(phost==&hUSB_Host)

{

 switch(id)

 { 

 case HOST_USER_SELECT_CONFIGURATION:

  break;

   

 case HOST_USER_DISCONNECTION:

  AppliState = APPLICATION_IDLE;

   

  // f_mount(NULL, (TCHAR const*)"", 0);    

  break;

   

 case HOST_USER_CLASS_ACTIVE:

  AppliState = APPLICATION_START;

  break;

   

 default:

  break;

 }

}

if(phost==&hUSB_Host1)

{

 switch(id)

 { 

 case HOST_USER_SELECT_CONFIGURATION:

  break;

   

 case HOST_USER_DISCONNECTION:

  AppliState1 = APPLICATION_IDLE;

   

  //f_mount(NULL, (TCHAR const*)"", 0);    

  break;

   

 case HOST_USER_CLASS_ACTIVE:

  AppliState1 = APPLICATION_START;

  break;

   

 default:

  break;

 }

}

}

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

Pavel thank you alot ; now the file sytem work

but I still have a small problem ; that host 2 some times still idle state ; i dont know why its happened.

what could be the channel?

[Pavel A.]

Then there are even more shared variables. Maybe, even a timer,,,
