Resolved! RTC time greater than 24 hours
Hello everyone, I am using an internal RTC on STM32L431. After running for 23:59:59 seconds, the time changes to 24:00:00 instead of 00:00:00, and the week day has not been incremented. Why is this?

STM32 USBD MIC AND STREAMING AUDIO
I am configuring USBD to turn the STM32F4 Discovery into a headphone, meaning it can play music through USB and transmit data from the PDM microphone to the computer. I have completed the music playback part, but I am now working on the recording par...
Azure RTOS threadX stack checking stuck in loop
I have an application where I have enabled TX_ENABLE_STACK_CHECKING. The application gets stuck in a do loop in the tx_thread_stack_analyze.c between lines 114 and 135. (H7.3.1.0) It is clear in the debugger that the loop will never complete. The...
STM32 TIM CC IRQ and USART RXNE IRQ
Hi everyone,I’m working on an STM32C0 setup where TIM1 CH1 (Pin A) and UART RX (Pin B) are physically shorted together, and I’ve encountered some unexpected interrupt behavior. Specifically, the UART RXNE interrupt always triggers before the TIM1 Cap...
Filex writing performance
Hello everyone, I am using a custom board with STM32H750 and I am trying to develop a file system with FILEX. The file system' s media is a uSD card with 10 MB/s baudrate which is communicating with the micro thanks to the SDMMC peripheral. The SDMMC...
Resolved! FATFS Failure with FreeRTOS
I am using the STM32H7B3I-DK for my project. I am trying to integrate uSD card usage with a touchgfx program. I have gotten a simple write to a file working on a non rtos project; however, when I use it in my project with RTOS I keep getting a hard f...
Resolved! SDMMC FATFS mount Hardfault
I have followed How to create a file system on a SD card using STM32CubeIDE the best I can using the STM32H7B3I-DK. With this board I do not see the DMA tab under SDMMC1, so I have skipped that. I am failing the f_mount(). I am using a touchGFX proje...
STM32H743 SPI DMA delay
Hello.I have a TIM3 configured to generate a PWM signal with frequency 1 MHz and duration 200 ns using CC1 channel. TIM3 also generates a DMA request on CC1.DMA1 is configured to transfer value 0xFFFF from AXI SRAM to SPI2_TXDR register, triggering t...
Resolved! Nx_TCP_Echo_Client Example Hard Fault if cable is unplugged while test running (STM32H573I-DK)
Hi,i am developing an embedded software based on the TCP Client example for CubeMX. During tests with large number of packets I have got an hard fault error. It seems that it happens on a re-transmit. The hard fault can be easy reproduced with origin...
