STM32 MCUs Embedded software

Trying to build freeRtos project with stm32u575zi (nucleo-u575zi-q), the freeRtos option not showing in the IOC file, I tried to download it and link to the project without success.... In the exemple project they use virtual file so i cant take it.

What needed to add freeRtos to the project ?

How to operate a SD card with two partition using FILEX?

I modified my project from filex demo in package STM32H7 AZURE, when i insert a SD card which has only one partiton, filex can read/write files on SD card. Then i format the SD card and create two partition, now filex cannot mount SD card. the error ...

I just wanna know is it possible to have multiple transmitting CAN ID from a IC? Is it possible to do it using HAL library? like change the TxHeader.StdId address before call the HAL_CAN_AddTxMessage().

STM32F745 dual CDC problems

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...

Internal USB FS PHY data lines sometimes are floating inputs. - Solution?

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...

STM32G474 jump to ST Bootloader without Boot0 pin

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 ...

RTOS ThreadX with NetXDuo in CubeMX uses a lan8742 driver file called nx_stm32_phy_driver.c wherein the HAL calls have too many variables. Has this been reported?

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 ...

I found a bug in HAL_RCC_OscConfig for stm32f2xx (file stm32f2xx_hal_rcc.c).

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...
