Bootloader selection. How is DFU boot detected? In AN2606 there is a Figure 68 that has an if-statement (USB cable detected). How is this done? What does it look for. I have connected PA11 (USB DM line) and PA12 (USB DP line) to other functions. I ...
I am trying to get a custom board with the stm32H745xi microcontroller to work as an USB MSC device. The board is designed by an eletronics expert and according to him the board should work. This is also confirmed when the device is put in boot mode ...
Dear Sir/Madam,I am quite new to the world of STM32 ,although I explore new things about them everyday.I have to use (internal) DMA of SDMMC of a MCU,to transfer large capacity of bytes from a SD Card to the internal RAM of the micro .For doing this,...
HiI am trying to create two TCP threads for my application.these packets are intended to control two VFDs which has two IP addresses(192.168.10.4 and 192.168.10.5) but same port number(502- modbus TCP).I am able to send packets to both the servers si...
Hi everyonei'm trying to get ethernet working on a custom stm32h750vbt6 board using lwip.i use a dp83848 interface module as physiccal in rmii mode. after some self try and error by myself and getting failed i found below subject on st and using it ...
Hi, I'm using STM32L072KZT6 microcontroller, and I'm trying to make USB DFU Standalone bootloader. I've done many bootloader standalone firmwares for STM32 MCUs, for F0, F1, F3, F4 series, and had never encountered this kind of a problem. It's not d...
I am developing an X-CUBE-USB-PD system that works with the STM32G070CB and FUSB307B.It is based on an example project for the FUSB307BGEVB, which behaves as a DRP.The library I'm using for it is M0_PD3_FULL.It works fine in most cases, but there is ...
Dear ST-community,in my project I am trying to sample with 4 timer-triggered ADCs simultaneously, what works quite well. Afterwards I am transmitting the data via USB to the PC. As long as I store the data in a buffer and transmit it after the measur...
HI All,I am using STM32F303 board and receiving data from UART3 in interrupt mode.but in my code UART only working in debugging mode when i use break points.at that time everything working fine but when I wan to use with out break points it will not...
