Serious Bug in USB - Keyboard - Stm32f722ze nucleo board

MMARI.1 · ‎2024-04-26

hi, i am trying to connect USB keyboard with STM32F722ze nucleo board but nothing worked out .

Not getting any output .

Before a year i have tested STM32f401ccu6 with USB keyboard and it's works fine .

looks like software package issue .

any solution on this ? .

Hi @MMARI.1 ,

Go on the GitHub - STMicroelectronics/stm32_mw_usb_host: Provides the USB Host library part of the STM32Cube MCU Component "middleware" for all STM32xx series and download as zip.

Unzip the files and copy all folders to \Repository\STM32Cube_FW_F7_V1.17.1\Middlewares\ST\STM32_USB_Host_Library by replacing the old files.

Then, open your HID_Standalone project in Repository\STM32Cube_FW_F7_V1.17.1\Projects\STM32F722ZE-Nucleo\Applications\USB_Host\HID_Standalone and Run.

I hope this help you.

Thank you.

As always... Have you started from a ready example for this Nucleo?

Projects/STM32F722ZE-Nucleo/Applications/USB_Host\HID_Standalone/core folder : usbh_conf_template.h file & usbh_conf_template.c file not found in CUBE IDE core folder

should i need to manually include the usbh_conf_template.h file & usbh_conf_template.c file into cube ide core folder ? .

Projects/STM32F722ZE-Nucleo/Applications/USB_Host\HID_Standalone usbh_conf.c file

hhcd.Init.Host_channels = 11;

vs

Cube ide / project/ USB Host / Target / usbh.conf.c

hhcd_USB_OTG_FS.Init.Host_channels = 12;
hhcd_USB_OTG_FS.Init.speed = USB_OTG_SPEED_FULL;

can you confirm which is right ?

Strange, files with "template" in filenames should never be copied from the repository to the user's project and be included into build. They are used as templates for actual project files.

Btw - there's no "core" subfolder in this example and no "template" files. Check that you have good sources.

hi, Again re-tested keyboard with stm32f401ccu6 it's working fine .

1. stm32f401:

from USB_HOST folder -> usbh.conf.c ->

USBH_StatusTypeDef USBH_LL_Init(USBH_HandleTypeDef *phost)
{
  /* Init USB_IP */
  if (phost->id == HOST_FS) {
  /* Link the driver to the stack. */
  hhcd_USB_OTG_FS.pData = phost;
  phost->pData = &hhcd_USB_OTG_FS;

  hhcd_USB_OTG_FS.Instance = USB_OTG_FS;
  hhcd_USB_OTG_FS.Init.Host_channels = 8;
  hhcd_USB_OTG_FS.Init.speed = HCD_SPEED_FULL;
  hhcd_USB_OTG_FS.Init.dma_enable = DISABLE;
  hhcd_USB_OTG_FS.Init.phy_itface = HCD_PHY_EMBEDDED;
  hhcd_USB_OTG_FS.Init.Sof_enable = DISABLE;
  if (HAL_HCD_Init(&hhcd_USB_OTG_FS) != HAL_OK)
  {
    Error_Handler( );
  }

  USBH_LL_SetTimer(phost, HAL_HCD_GetCurrentFrame(&hhcd_USB_OTG_FS));
  }
  return USBH_OK;
}

Tested with keyboard not working & not sucess

2. stm32f722ze:

from USB_HOST folder -> usbh.conf.c ->

USBH_StatusTypeDef USBH_LL_Init(USBH_HandleTypeDef *phost)
{
  /* Init USB_IP */
  if (phost->id == HOST_FS) {
  /* Link the driver to the stack. */
  hhcd_USB_OTG_FS.pData = phost;
  phost->pData = &hhcd_USB_OTG_FS;

  hhcd_USB_OTG_FS.Instance = USB_OTG_FS;
  hhcd_USB_OTG_FS.Init.Host_channels = 12;
  hhcd_USB_OTG_FS.Init.speed = USB_OTG_SPEED_FULL;
  hhcd_USB_OTG_FS.Init.dma_enable = DISABLE;
  hhcd_USB_OTG_FS.Init.phy_itface = HCD_PHY_EMBEDDED;

community member was success in usb using stm32f746

from USB_HOST folder -> usbh.conf.c ->

USBH_StatusTypeDef USBH_LL_Init(USBH_HandleTypeDef *phost)
{
  /* Init USB_IP */
  if (phost->id == HOST_FS) {
  /* Link the driver to the stack. */
  hhcd_USB_OTG_FS.pData = phost;
  phost->pData = &hhcd_USB_OTG_FS;

  hhcd_USB_OTG_FS.Instance = USB_OTG_FS;
  hhcd_USB_OTG_FS.Init.Host_channels = 8;

    Error_Handler( );
  }

  USBH_LL_SetTimer(phost, HAL_HCD_GetCurrentFrame(&hhcd_USB_OTG_FS));
  }
  return USBH_OK;
}

if compare three of usbh.conf.c file

1.stm32f401ccu6 - > speed = HCD_SPEED_FULL; Host_channels = 8;

HCD_SPEED_FULL-> Open Declaration -> stmf4xx_hal_hcd.h file getting opened .

2.stm32f722ze -> speed = USB_OTG_SPEED_FULL ; Host_channels = 12;

USB_OTG_SPEED_FULL-> Open Declaration -> stmf7xx_II_usb.h file getting opened .

3.stm32f746 -> speed = HCD_SPEED_FULL; Host_channels = 8;

HCD_SPEED_FULL-> Open Declaration -> stmf47xx_hal_hcd.h file getting opened .

usb working controller stm32f401ccu6 & stm32f746 are calling proper Heder file .

usb not working controller stm32f722ze is calling improper Header file .

i believe stm32f722ze having USB software bug . please help me to use this board stm32f722ze .

Just modifying USB_OTG_SPEED_FULL to HCD_SPEED_FULL will not work looks USB file having lot of link which is out of my limit .

hi @KDJEM.1 @Pavel A.

i couldn't find any middleware update option menu in ioc or in the project file.

can you please tell me small procedure .

hi, after USB middleware update keyboard started working with USB_FS via PA12 & PA 11.

then i disabled USB_FS (pin PA12 & PA 11) and enabled Internal_Phy_Fs via PB15&PB14 found keyboard not working .

i need 2 USB_FS line for different purpose
