I Am facing another issue with this board.
Her is my USB setting
- USB_OTG_HS is Device Only
- NVIC Settings
- USB OTG EndPoint In/Out 1 INT checked
- GLobal Int checked
- USB Device
Then the init fails in USB_CoreReset with timeout.
I checked the HAL_PCD_MspInit and pins looks OKay.
static HAL_StatusTypeDef USB_CoreReset(USB_OTG_GlobalTypeDef *USBx)
{
__IO uint32_t count = 0U;
/* Wait for AHB master IDLE state. */
do
{
count++;
if (count > 200000U)
{
return HAL_TIMEOUT;
}
} while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_AHBIDL) == 0U);
/* Core Soft Reset */
count = 0U;
USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST;
do
{
count++;
if (count > 200000U)
{
return HAL_TIMEOUT; <<<<<<<<<<<<< FAILS
}
} while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST) == USB_OTG_GRSTCTL_CSRST);
return HAL_OK;
}
I just discovered that My USB config
/**USB_OTG_HS GPIO Configuration
PC0 ------> USB_OTG_HS_ULPI_STP
PC2_C ------> USB_OTG_HS_ULPI_DIR
PC3_C ------> USB_OTG_HS_ULPI_NXT
PA3 ------> USB_OTG_HS_ULPI_D0
PA5 ------> USB_OTG_HS_ULPI_CK
PB0 ------> USB_OTG_HS_ULPI_D1
PB1 ------> USB_OTG_HS_ULPI_D2
PB10 ------> USB_OTG_HS_ULPI_D3
PB11 ------> USB_OTG_HS_ULPI_D4
PB12 ------> USB_OTG_HS_ULPI_D5
PB13 ------> USB_OTG_HS_ULPI_D6
PA8 ------> USB_OTG_HS_SOF
PB5 ------> USB_OTG_HS_ULPI_D7
The PA5 USB_OTG_HS_ULPI_CK
as
GPIO_InitStruct.Pin = GPIO_PIN_3|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF10_OTG1_HS;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
[...]
__HAL_RCC_USB_OTG_HS_CLK_ENABLE();
__HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE();
I verified with the Ossciloscope and PA5 [USB_OTG_HS_ULPI_CK]
does not have a clock.
I tried on 2 boards, and I dont think both boards are deffective.
Any help would be appreciated.
