USB OTG Bootloader for STM32F7 series

Hello, is there any example or information on how to implement a USB OTG bootloader (via a flash drive) for STM32F7 series?

Hello group. I'm working on a project with stm32-f412zg mcu board and having some trouble in configuring multiple timers using FreeRTOS for stm32-f412zg to control ws2812b led strips. I really need help in implementing it to complete the project. Any help

We are using WS2812b LEDs for output signals. We are able to configure multiple timers simultaneously but the colors are not what we trying to give signal to the WS2812b LEDs. With individual LEDs everything is fine and we are controlling it as we wa...

FatFs with SD 4Bit Bus & RTOS is not working (f_open) in LFN Mode

Hi I've configured FatFs for SD 4Bit Bus. I'm using FreeRTOS.When USE_LFN = 0 then all works well. Writing and reading to/from the SD card is working as it should.As soon as I enable USE_LFN = 3 (in CubeMX) f_open returns FR_NO_FILESYSTEM (13).check_...

Resolved! How to repeat USB enumeration with a maxpower of 100mA if a previous 500mA request was rejected by the hub

Hi,I want to design a combined USB<->RS485 converter cable based on the CDC profile with integrated charger detection. The MCU of my choice is the STM32F401CB. The release of battery charge is done by switching an overcurrent protection chip TCKE805N...

STM32G031 Interrupts not working after jump from IAP

Hi allI am working with STM32G031F4 on a custom board and using STM32CubeIDE.I have a small bootloader that jumps to the application after some time (based on HAL_GetTick()), but none of the interrupts seems to be running after the jump- namely UART ...

Can I use the STM32F4 PTP clock without an RMII clock?

I'd like to use the PTP clock peripheral in my STM32F427 for timekeeping - but without using the rest of the ethernet functionality, or dedicating any pins to it.I prefer the PTP clock to the RTC as it offers a 32-bit subsecond (rather than the 16 bi...

Resolved! Can the OTG_HS_DM and OTG_HS_DP pins be used for USB full speed operation?

On page 186 of the datasheet for the STMF407xx the diagram for using USB FS shows that the pairs PA11/PA12 (OTG_HS) or PB14/PB15 (OTG_FS) can be used to connect the USB DM and DP lines. However, the pinout table on pages 52 & 55 explicitly list the f...
