I have a nucleo-stm32f756zg board. I can't make lwIP stack working, which I tested with ping. I have read the relevant documentation (e.g. rm0385, um1974). I have read the official stm32 tutorial for stm32H7 (https://community.st.com/s/article/How-to...
I try to build system that communicate via ethernet and also wants to update software in the same way. The question is what is the best way to handle this kind of system?for example :1) my own bootloader + flash program x 2 ,bootloader will manage it...
I am using an stm32h23zg, FreeRTOS plus TCP stack to create a TCP client.I checked, I can bind the socket to many values (tried 1, 52 and 1000, all 3 worked) but I couldn't find any recommendation on which port to use.On computers it is usually recom...
Hello, I am experiencing a problem implementing a simple bootloader similar to the one showed by ST on youtube. I decided to use 32K of flash for the loader, while the remaining flash is available for the application. Linker file of the bootloader:ME...
I am writing a bare-metal USB CDC device stack on the STM32F411 discovery board which has a STM32F411VET6U controller. During enumeration I can see that the DAD field is not responding in the DCFG register. In other words when the stack tries to writ...
I'm debugging an issue where my application is using device mode USB with CDC-ACM and when I come to transmit a data packet on a bulk IN endpoint that is either 64 or 128 bytes in length, the data is not received by the host until either a different ...
In the OTG USB implementation, in USB_DevInit(), the PFIVL field of OTG_FS_DCFG is supposed to be written, eg. here, in the following way: USBx_DEVICE->DCFG |= DCFG_FRAME_INTERVAL_80;the DCFG_FRAME_INTERVAL_xx constants are defined in the respective ...
Hello I just found out that the HAL_Delay() delay actually takes 1ms longer than the desired value. Why?STM CUBE IDE 1.9.0STM32F072RBT6
Hi I'm using STM32F429ZI Nucleo board to work on integrating C270 Logitech camera through USB host. I'm not getting any interrupt in the USB IRQ handler when the device is connected. And it is said that LD8 LED will be ON when the USB is in device or...
