STM32H7 Ethernet transmission comes to halt, eventually related to TX queue underflow interrupt?
Hi,I experience strange behaviour with the just reworked H7 ethernet driver in STM32H725 with LwIP + FreeRTOS environment. A continuous transmission of UDP frames (bursts of 3..4 frames every ~ 50 ms) comes to halt after just a few successful loops. ...
STM32F401RE multiple virtual com port issue?
HI,I am using a stm32f401RE chip on my board, a single virtual com port is working fine, but if it is possible to run twice virtual COMS? and what are the processing steps?Regards,Naren
Determine USB-cable connected/disconnected status and transmit-in-progress status without being dependent on interrupts?
I'm working with the Nucleo-64 development board with an STM32L476 microcontroller and I'm using the USB source code that STM32CubeMX has generated for me. In my project the peripheral interrupts have the same priority as OTG_FS_IRQHandler and hence,...
STM32L4 Won't Trigger USB Interrupt on One Project, But Will On Another
I have a custom board based around the STM32L496 that creates a USB HID device. I have two projects (built in IAR Embedded Workbench), both of which have this board and micro as their target. On the exact same board, one will enumerate USB at FS, one...
How to change DBANK for Provisioning using B-4S5I-IOT01?

Is there any USB using virtual com port example with the NUCLEO-U575ZI-Q?
Hi,I am trying to test the HSI48 clock for the USB (with the CRS SYNC USB). But I don't find any simple example for the NUCLEO-U575I-Q... Now that the USB-DEVICE is not supported in CubeMX for the U5 (only on github) I am really struggling with the U...
