Hello,I'm debugging the following piece of code that is executed as part of the fault handler:currentExceptionData.data.CFSR = SCB->CFSR;currentExceptionData.data.HFSR = SCB->HFSR;currentExceptionData.data.DFSR = SCB->DFSR; //TODO: Not copied correct...
Hi guysI made a project with CubeMX for a STM32F334. This project built fine already multiplet times.Now, I get suddenly this error message:#error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"As I said, the p...
Hi,I am debugging an issue with infrequently occurring Ethernet RBU's in my own Stm32H723 application and decided to check the official Stm32 ethernet examples to see if they were having the same issue. I imported the Stm32H723 LwIP_HTTP_Server_Socke...
I have setup my STM32 MCU to be a USB Device with OTG FS and when I list the details of the device on my computer, I can see that the USB endpoint used for data transfer is of type Bulk. It works perfectly fine, when I use the function `CDC_Transmit_...
Hi all,We are currently using the stm32h5-hal-library in our project. Our preference is to use the LL drivers rather than the HAL and for the Octospi, we only see a HAL drive for it (stm32h5xx_hal_xspi.c). Is there a LL driver equivalent for this? I ...
I am using internal Temperature Sensor stm32h743zit6 , i notice that when i connect power some time after that it stable temperature approximately 46 degree or 47 degree, after i start streaming it came temperature also stable on this 46 degree o...
Hi, I am trying to use a Nucleo-H745ZIQ to implement the USB CDC HOST functionality over the USB OTG FS port. I succeeded to do it and make it work if the device connected to my board is another STM32 board which is configured as an usb device, and t...
Hi!when I run the HAL example code LwIP_HTTP_Server_Netconn_RTOS I get HAL_ETH_ErrorCallback() called on every packet, but the program seems to work fine.its this bit that gets called (so something hapenning with DMA)if((HAL_ETH_GetDMAError(heth) & E...
I am trying to implement MODBUS-TCP on a TouchGFX generated project. I have successfully enabled Ethernet by following this tutorial on this forum: How to create a project for STM32H7 with Ethernet and LwIP stack working and can ping my board.In the ...
I inherited an old STM32 project (STM32F373) that uses FreeRTOS and the old Standard Peripheral Library (apparently v1.0.0, dated Sept 20, 2012). Among other things, the project uses USART1 with interrupts to receive LIN messages, and also has a task...
