DFU Mode with L152 / L082

I am developing a project for the L082 (as we have stock of these) but am currently using the L152 discovery board to get things started. This is going well but I thought that I would try the DFU mode to allow easier field software updates. I tried...

Needing help customizing the USB setup on STM32H750 to connect as a "Generic Bulk Device" under the "Universal Serial Bus devices" in the Device Manager.

Switched from another processor to the STM32H750 on updated boards, and trying to keep the PC communication the same so it is seamless (or as seamless as can be) for the user experience. Previous boards connected up to Windows as a Generic Bulk Devic...

STM32H743 system bootloader does not work by USART2

I would like to download code from Raspberry Pi to NUCLEO-H743ZI2 board. On RPi, I use STM32flash app and 2 GPIOs for NUCLEO's NRST & BOOT0. STM32flash generates the signals properly (I see that current STM32 application does not start) and I acquire...

STM32F4 HAL V1.26.2 USB 2.0 host mode MSC over ULPI phy not stable, some functions must be back-ported to 1.25.2

We have found out two stability issues inside the current version of STM32F4 HAL driver.Chip used:STM32F429ZI, External ULPI: USB3300, Vbus control using STMPS2151STR, ESD protection, EMI protection.(see scheme appended)Compiler: GCC / GNU Arm Embedd...

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]);
