USB HS CDC stop working if Internal IP DMA is enabled on STM32H750

Project created by the latest version of CubeMX with the latest HAL libraries with almost no user code yet, only USB HS with external phy and USB CDC middleware enabled. Heap size and stack size are all set to 0x0800.There is a USB3300 and an externa...

When I plug in 64 and 128 gb usb, it says the library is constantly connected and disconnceted. But 16gb usb works clearly.

Hello,I use USB MSC modules codes which provided by ST ( HAL Library USB )Actually I can use correctly my application with 16GB ,8GB ,4GB USB.But When I plug in 64GB USB or 128GB, it is not working.it is periodically transmit "USB Device disconnecte...

Hi,First I'm new to the STM environment.I'm setting up the Board to test some stuff, with raw LwIP. I'm having a weird issue, where the board freezes when i plug in a connected ethernet cable. I made no other changes (exept one, look below point 3)Co...

I am using STM32H7A3 board. I am trying to integrate SD Card using SPI. I am getting FR_DISK_ERR when I try to do f_mount. Attached source code.

When i tried to give Pull ups for SPI pins except SPI1_SCK, i am getting FR_NOT_READY error.I am completely stuck in this issue. Please have a look into this and provide a solution for me.Thanks in advance.Jestina

Hi, I am using a STM32L496. On the board is a buzzer. If the buzzer works, an USB connection lost the transmit functionality. Receive is still ok. The supply voltage is stable regards Josef

Integration of a position dependent library (binary) in a threadx module ( position independent )

Hi, I am working on threadx. So to set the context, Module manager will host modules.All the modules are compiled as position independent. Module manager however is not position independent.Scenario : a third party library (binary) has to be used in ...

How to stream out data via USB HS with CDC Interface

Hi,I want to achieve following:I want to read out an ADC (16-bit at 1MSPS) via SPI and stream those data to a Host PC with the Nucleo-F722ze and the USB_CDC_Interface.The amount of data per second is to high (16Mbit/s) for USB_FS so I am using USB-HS...
