DFU programming error

If I use the DFU programming over USB with STM32CubeProgrammer, the error occurred and the device doesn't start properly, but if I download the same program with ST-LINK everything runs ok. The MCU is STM32 G473.I can connect the MCU over the USB, an...

Will ST be kind enough to provide a simple and complete example of implementing CDC (simple implementation of USB to UART communication similar to CP2102 and others) on an MCU e.g., STM32F103 or STM32F401, including any caveats?

Help getting the en.STM32Cube_FW_F7_V1.15.0 (or later versions) package to run on anSTM32F7 Discovery kit with the STM32F746 uP

Hello, When I compile the files in the package and flash the board, all I get is a white screen. I have attempted to flash with other code packages as well and have not been able to get any to work. The only one I have had any luck with is rebuild...

About the Tx_CMSIS_Wrapper example

I am new to STM32, been looking at it just a week, have an L4R9 Disco board. I am familiar with the CMSIS RTOS2 api, and have used RTX previously. Was interested to see the Tx_CMSIS_Wrapper example, as it shows how an RTOS2 facade is added to Azure R...

32F417: How does USB CDC OUT (PC -> target) flow control work?

I have my board running well, and flow control works in the "IN" direction (board -> PC).But there are strange issues. I am testing with a loopback program which has variable size packets and at a point which is very close to 1024 bytes I see a lot o...

STM32G030xx driver - Macro __HAL_FLASH_CLEAR_FLAG might be wrong

Related to the STM32G030xx HAL driver.Many examples of the macro __HAL_FLASH_CLEAR_FLAG use multiple flag values ORed together. The comments on this macro seem to suggest that this is OK since the plural form is used on flagS ("Clear the FLASH pendin...

Is it possible to change the option bytes for STM32G030C6 using J-Link utility?

Use caseI'm planning to perform STM32 firmware update over I2C. For this I need to communicate with the STM32G030C6 system memory boot loader using some other host controller. In our system we'll be using the BOOT0 pin to decide the boot area at the ...

Ethernet MAC Filtering

Good morning friends,Now I receive multicast on STM32F437, it works. But I would like to add filtering. And I have a problem with that.IGMP and others, I have it enabled.Now my settings.macinit.MulticastFramesFilter = ETH_MULTICASTFRAMESFILTER_PERFEC...
