Hey,After debugging for a long time I still haven't been able to find the cause of ethernet interrupt not triggering for up to 1500 ms.What I'm doing is opening a socket on my STM32F4 + LAN8742A. I am running a script that sends an "heartbeat" every ...
Good day,I have a NUCLEO-STM32F767ZI and a problem with the STM32 CUBE IDE. When I create a project in version 1.5.1 with ETH, FreeRTOS and LWIP everything works fine. When I create the same thing in the latest version, the generated code falls into ...
When jumping to bootloader from software for devices such as the stm32l4, why is it necessary to remap system memory to address 0x0000 0000 in address space by calling __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH? On the contrary, the stm32H7 doesn't require...
I am following an the example from MOOC;https://www.youtube.com/watch?v=nSLN_WM2TOc&list=PLnMKNibPkDnExrAsDpjjF1PsvtoAIBquX&index=59&t=889sI can't make it work, apparently LPTIM trigger interrupts continuously.I create a fresh project to reproduce pr...
Hello again,Here's what I want to do:1) wait for the UART_FLAG_RXNE to be set2) receive one character3) switch based on that character (character is saved for further processing)4) receive the proper number of following characters based on the comman...
My previous question was how to detect a cable and they said to use a EXTI to receive a VBUS detection. The customer wants to use USB to program a blank device (so nothing configured) and EXTI is a block of interrupts and could be multiple pins. Ple...
I downloaded Azure-IOT example for STM32U5 which works on IAR. I am trying to add a c file to secure application. I am able to compile and even see that function is hit while I debug.After this function call, the board is getting rebooted with below ...
I'm wondering if i'm missing something here.I've hooked up BOOT0 to the 5V pin on CN2. I have nBOOT1 set to 1, and i'm connected to the device via the ST-LINK as the other usb port doesn't seem to be active. I've also installed the udev rules, and ju...
