Hello.I have found a bug in USB implementation in STM32CubeH7 (1.4.0 - 1.6.0). Steps to reproduce:1) Open the project from STM32H743I-EVAL\Applications\USB_Device\MSC_Standalone\MDK-ARM directory2) Apply HEAP fix from https://github.com/STMicroelectr...
I use stm32F746 & FreeRTOS & SDMMC & DMA.When I use f_open in somewhere it will return FR_NOT_ENABLED...But in my system have the other f_open & f_write is normal work(I am not remount).My English is not very good,if anything can't understand pl...
Hello,I am using fatfs library developed by http://elm-chan.org/ for reading/writing file system in usb mass storage using stm32f4.As I know, for improving speed throughput one should write data buffer in a multiple of sector size (512B). As stated i...
Hello:Problems with the USART1 receive call on this device. Or is it me? I hope not.I have a serial decode option on my scope. I can see what I send out, and what comes back, every byte. This is my call to receive:rxChar[50];HAL_UART_Receive_IT(&huar...
Hi, All!I am writing a driver to support a custom usb device (like CDC Class). I use example stm324xG-EVAL_USBH-HS (yes, HS). I have a recording made using a wireshark (linux - device):1) make the first request2) get a confirmation 3) asking for an a...
Hello,I'm working with the CAN Module from the STM32F446RE board which has the MCU mentioned in the title. I'm trying to transmit some data on the UART via Tera Term terminal and take this data and send it via Loopback mode and read it back. For star...
I am try to do the project with this controller as a usb mass storage device for a small application. what steps i will do for that, but i already tried the tutorial given by the st.com. but its discussed for f4 series but need f103 series. please he...
I am developing an application using an STUSB4500 and an external MCU STM32G031K8 that should be able to read USB PD Source capabilities and allow the user to dynamically set custom PDOs.I have based the majority of my code off of the example softwar...

From the function name of 'HAL_GetTickFreq()' function, I expect that it returns tick frequency in Hz.But I experienced that it returns tick period in milliseconds. If tick frequency is 1000 Hz, then it returns 1, that value comes from HAL_TICK_FREQ_...
