HiI would like to store the call stack when the STM32H7 crashes. I implemented unwind.hThe code works on a bare metal simple est code but not with FreeRTOS is runningAny idea as to why? The code static uint16_t CallStackAddr;CALLSTACK_DATA uint3...

Hi I have used STMCubeIDE 1.11.0 (Cube 1.6.1) to generate the code for USB CDC interface for STM32G0B1.The code is as CubeMX would generate. I have not modified the code at all.When I plug the device into a PC I get "USB device not recognized" I have...

I have an application using STM32H743 we wish to use the LPUART using the interrupt. We have a bootloader that is located 0x08000000 until 0x08020200. According to system_stm32h7xx.c we should move the vector table in steps of 0x200 this works for al...

I have a project using both RTOS and LWIP. I updated my IDE today and the project will not compile I get the following error below that errno is declare multiple times. errno is only declared once in the project. Even if I create a project with RTOS ...

Hi.It is now working. I used a STM32G474 example code to figure out what is wrong.There was 3 errors in the auto generate code.The 48MHz clock was not started. Missing USBD_Clock_Config(); in void MX_USB_Device_Init(void))The USB interrupt was not en...

Hi As you can see the internal 48MHz clock is by default linked to the USB. So that's not the issue I think. I have even tried setting Pclk to be 48MHz still did not work.David

HiThanks for the replies. I now know why it did not work. I have changed my code to use vector table aligned to 0x400.

That was not the solution the SPI is configured as full Master so when you can HAL_SPI_Receive it then calls HAL_SPI_TransmitReceive. I found out by testing the HAL function is not Thread safe. I changed the code to use HAL_SPI_TransmitReceive_IT. It...

STM32H743 jumping to wrong interrupt when I move the vector table when using LPUART

Issue with IDE 1.9.0 and 1.10.0 with STMH7 RTOS + LWIP

I am using STM32H7 SPI4 with RTOS. when I call errorcode = HAL_SPI_Receive(&hspi4, pbRecv,ulLen,100); I occasionally returns an error The error is OVR and time out. How can you get OVR when polling SPI?
