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?

Resolved! 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...
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...
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...
Resolved! Not working STM32U585 QUADSPI interface with external flash(NOR) in memory mapped mode
Hi folks,I am facing one issue for external flash in memory map mode, I am using stm32U585 . I am unable to write/read/access external flash(NOR) while in memory mode. but in Indirect memory mode all actions are working.but in manual they have give...
LPUART consumes extra 3mA while STOP2 mode
I'm using STM32WB55. The reference example is BLE_p2pServer with custom modifications. The power consumption of STOP2 mode ( by enabling CFG_LPM_SUPPORTED ) is around 6mA (board level), and it will be around 9mA after LPUART is enabled with RCC_LPUAR...
Resolved! I3C HAL_I3C_Ctrl_MultipleTransfer_IT read/write data
Hello, Currently I implement a I3C function of mass readback data from the target device. I use the HAL_I3C_Ctrl_MultipleTransfer_IT, the mass write data into target device that is worked. But readback data operation is not worked well. If it readba...
