I write a simple blinking project on STM32F4 Discovery board.It calls HAL_Delay() function for blinking effect on one LED.But the code hanging when reach HAL_Delay().When I debug, the HAL_Delay() stuck at while() loop in there.Here my code :#include ...
Dear STM support,I'm trying work on waking up from stop mode with magic packet.In debugging mode, I caught a breakpoint in method ETH_WKUP_IRQHandler() and succeeded in the device waking up.But not in debugging mode, the device was not waken up. (I...
Hi,I'm novice with the STM32 microcontrollers and this community.I'm trying to write to the flash memory of STM32L4R5 in 'FLASH_TYPEPROGRAM_FAST' mode of the HAL_FLASH_Program().The flash of the MCU is configured as Single Bank.Writing to the flash o...
Hello, I need to understand if it's possible to use both USB HID keyboard and mouse in a project powered by a STM32F469. I have thought about plug a mini HUB and connect both keyboard and mouse. Is there something I can start from? I have searched a ...
I have a self powered STM32F446 with 24 MHz oscillator, not crystal. When trying to activate the bootloader mode, I get variable results. Sometimes it shows up properly, sometimes it shows up but in a corrupted type of state, and sometimes it doesn't...
I am using the blocking calls and the master_receive most times does not behave. The master_receive very often fails to ACK data from the slave and continuously holds SDA low. The master sends the slave address with the read bit set, the slave sends ...
I have made my own PCB board with F411 MCU.The USART2 does not work well if I use LL driver.This is the init code generated by CubeIDE.static void MX_USART2_UART_Init(void) { /* USER CODE BEGIN USART2_Init 0 */ /* USER CODE END USART2_Init 0 ...
I am prototyping a new board upgrade to USB-C by connecting an X-Nucleo-SNK1M1 board containing the TCPP01-M12 to our existing USB device board that uses a STM32L476. The device is battery powered and will only need default 5V power. All that works...

Hello,I am trying to interact with the FDCAN bootloader of the STM32L5.I had no issue with the CAN bootloader of the STM32L4 (AN3154), but with the STM32L5 I am unable to even get an ACK from the target. 1) According to AN2606 Rev 47, the bit-rate s...
