Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello,I have been testing modifications for STM32 default USB library stack that was modified to support dual CDC. The code is working fine on STM32H745 MCU. The idea was to now use this same library for F745 to communicate with Qt app on PC but ther...
Hi dear support people,floating CMOS inputs in general pose both serious hardware and software problems, as we all are quite aware of.Regardless, the D- line of the STM32H7 USB FS PHY (used as a USB device role) is floating, when the host USB cable i...
Hi,I'm trying to boot to the system memory so I could use ST bootloader (USB-DFU in mind), but unfortunately not succeeded.I have a custom board with a STM32G474RE and another similar version with a STM32G473RB. I cannot use the PB8/Boot0 pin, cause ...
The calls in particular are HAL_ETH_ReadPHYRegister and HAL_ETH_WritePHYRegister. In the HAL driver files, specifically stm32f7xx_hal_eth.c, these routines take 3 variables and not 4. For example, in the nx_stm32_phy_driver.c, the function for Read ...
When this function is called with the OSC configured, e.g. from bootloader, it checks if the PLLM/N/P/Q in RCC PLLCFGR reg are the same as requested. That check fails, even if the parameters in the second config request are the same.Problem is locate...
Hi,Sometimes (randomly) I encounter a problem in firmware, even though sometimes it works well for hours without any problem.The whole idea of the firmware is that it receives data over USB HS with DMA enabled and initiate a transfer over another int...
I need some help, I have found USART1 and USART2 however I can't understand where LPUART, USART3 and USART4 are. Also I don't understand what NC_UART0, RFT_UART1 and RFT_UART2 stand for. I know these last 3 are related to the modem type1sc. I also kn...
Hello,I am trying to create project with STM32F407/429 discovery and AzureRTOS and getting compile errors.Attached the cubemx project.The errors appear in KEIL, IAR and CubeIDE. (I tried same cubemx configuration for STM32H743ZI without any compile e...
I'm trying to program STM32G030 but I don't have a ST-LINK.I wonder is it possiable to program this chip through UART interface? There is a LED-BLINKING program programed by distributer in main flash memory. I have tried to pull BOOT0 to VCC and rese...
