STM32 MCUs Embedded software

Seeing an issue with USB interrupts on STM32H742 only on Endpoint 1 USB Enumeration works fine. I am seeing HAL_PCD_DataOutStageCallback for endpoint 0 but not HAL_PCD_DataOutStageCallback for endpoint 1. Any ideas what I might be missing?

Initialization sequence:hpcd_USB_OTG_FS.Instance = USB_OTG_FS; hpcd_USB_OTG_FS.Init.dev_endpoints = 9; hpcd_USB_OTG_FS.Init.speed = PCD_SPEED_FULL; hpcd_USB_OTG_FS.Init.dma_enable = DISABLE; hpcd_USB_OTG_FS.Init.phy_itface = PCD_PHY_EMBEDDED;...

Hiii there, Recently , I am working on STM32 Nucleo-H745zi-q and i am not able to configure the ethernet protocol in same. Whenever i try to ping it , it not acknowledge at all. Please help me with same. Thank You

STM32F4 Ethernet interrupt not triggering for up to 1500 ms after random period of time.

Hey,After debugging for a long time I still haven't been able to find the cause of ethernet interrupt not triggering for up to 1500 ms.What I'm doing is opening a socket on my STM32F4 + LAN8742A. I am running a script that sends an "heartbeat" every ...

NUCLEO-STM32F767ZI and STM32 CUBE IDE

Good day,I have a NUCLEO-STM32F767ZI and a problem with the STM32 CUBE IDE. When I create a project in version 1.5.1 with ETH, FreeRTOS and LWIP everything works fine. When I create the same thing in the latest version, the generated code falls into ...

How to combine HAL_I2SEx_TransmitReceive_DMA with arm_biquad_cascade_df1_f32? Due to data Receive as uint16_t but the arm filter input is float32_t.

Why is remapping necessary for jumping to bootloader?

When jumping to bootloader from software for devices such as the stm32l4, why is it necessary to remap system memory to address 0x0000 0000 in address space by calling __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH? On the contrary, the stm32H7 doesn't require...

Example on MOOC about RTOS tickles doesn't works.

I am following an the example from MOOC;https://www.youtube.com/watch?v=nSLN_WM2TOc&list=PLnMKNibPkDnExrAsDpjjF1PsvtoAIBquX&index=59&t=889sI can't make it work, apparently LPTIM trigger interrupts continuously.I create a fresh project to reproduce pr...

Hello again,Here's what I want to do:1) wait for the UART_FLAG_RXNE to be set2) receive one character3) switch based on that character (character is saved for further processing)4) receive the proper number of following characters based on the comman...

Where does Bootloader for STM32G0B1M1 look for a USB cable? My previous question was how to detect a USB cable, but the answer was just use VBUS and an EXTI to detect. Which interrupt does the bootloader monitor for a cable?

My previous question was how to detect a cable and they said to use a EXTI to receive a VBUS detection. The customer wants to use USB to program a blank device (so nothing configured) and EXTI is a block of interrupts and could be multiple pins. Ple...
