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...
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...
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...
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...
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...
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...
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...
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...
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...
Hi,I'm using an STM32H7A3ZI MCU, with freeRTOS, fatFS & DMAI have set the SDMMC2 peripheral with 4 bit mode & DMA (by default in STM32H7 MX config). I have implemented the code from this example to test my SD card (microSDHC 32Gb, also test on 2Gb SD...
