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...
I am using STM32L082KZT6 and want to use bootloader with USB. I have read instruction and in my perspective I thought that just by connecting boot0 pint to high then usb bootloader mode would start. But it didn't. I putted the schematic picture belo...
Following the recent and exciting announcement that ST and Microsoft are teaming up to ensure the integration of Azure RTOS in the STM32Cube environment, we feel like it is time to share more details directly with our community of developers.While ST...
How does the FIFO created in MX_USB_Device_Init() match the endpoint?In the USBX document of Azure, the descriptor is directly made into an array, while the sample program uses a lot of functions to implement it. What are the benefits of this? Not ea...
Hi!I'm using FatFS R0.11 with STM32F373 and sometimes it works to use FATFS and sometimes not.These are the issues I got and I don't know why. Can it be something with NVIC interrupts that causing issues with the FatFS library?Mount SD card: Mount SD...
Hi,We are currently using H745 in our design and we noticed this little excerpt in the bootloader manual (AN2606):" Additional reset needed after power off/on to enable connection to the BL interfaces "It seems that not all resets are equal and the r...
Using STM32CubeMX to make a DFU bootloader, I want to light a LED whenever USB packets are exchanged, to indicate that a DFU binary is being transferred....but I can't find the right callback to place my HAL_GPIO_WritePin (which makes the LED light u...
I am using STM32CubeIDE and have used the linker to change settings, so have a pretty good grasp.I have read on custom bootloaders but not found how they deal with the following issue, as it seems ignored in the demo code. The custom bootloaders show...
i am integrating STL XCUBE class-B V2.2.0 Packages with STM32L433 controller here issue RAM startup self test, if (STL_FullRamMarchC(RAM_START, RAM_END, BCKGRND) != SRAMTEST_SUCCESS) failed, when i run debug its jumping to hard fault , what could be...
i have integrated STL XCUBE class-B 2.2.0 Packages with STM32L433 controller here i am facing Startup RAM test issue The RAM-test procedure STL_FullRamMarchC(RAM_START, RAM_END, BCKGRND) != SUCCESS) of the IEC 60335 SelfTest library ends with a HardF...
Function "PWM Generation CH2N" can not work, channel CH2N don't output PWM signal. But after I changed "tmpccer &= ~TIM_CCER_CC2NE;" to "tmpccer |= TIM_CCER_CC2NE;" (in file stm32h7xx_hal_tim.c), it works well.Hoping developers of HAL library will fi...
