Potential race conditions in H7 Ethernet example(s)

I am sorry if the question was already asked, but I cannot find something similar.I have created LwIP_UDP_Echo_Server example for STM32H735G-DK, and after some efforts it works. So far so good. Now I am porting the code to my actual project. I am stu...

Access FDCAN Bootloader from Application

I am working on a STM32H725IGT microcontroller. I need to update the application code running on it over FDCAN, I have read through the AN5405 document, and set my application's FDCAN1 settings to be similar to those mentioned in AN5405. I need to sw...

Problem with USB: usbd_customhid.c file from the stm32cubeh7 in USBD_CUSTOM_HID_DataOut rutin I get a Hard Fault exception interrupt. on this line ((USBD_CUSTOM_HID_ItfTypeDef *)pdev->pUserData)->OutEvent(hhid->Report_buf[0], hhid->Report_buf[1]);

Azure RTOS with NUCLEO-H745ZI-Q Board.

I am testing Azure RTOS with NUCLEO-H745ZI-Q Board.I made a simple project through CubeMX and then downloaded it.By the way, it doesn't go beyond MX_ThreadX_Init().It looks like an infinite wait on __tx_ts_wait .Are there any additional settings miss...
