Hello,I have a Nucleo H743ZI2 on which I am communicating with the micro AB USB port through USB OTG. Up until now I always had the main USB (STlink) plugged in to power the board. Eventually I want to power the nucleo board with an external 3.3 powe...
Hi,I'm a french embedded developer.At my office, i use a STM32F767GTx custom board with a N25Q128A QSPI Flash memory, and my software works fine.Recently, i add a WebServer using LWIP and HTTPD.I have some CSV files on my flash memory, generated by t...
I'm trying bootloader of nucleo STM32G474RE and faced several issues : It seems only 8bytes alignment is working for flash writing while AN2606 table.7 says it requires 4bytes alignment.In an2606 table.141, valid RAM area is from 0x20000000 to 0x2000...
Hi, I have an example that correctly responds to ping 192.168.0.100 on the NUCLO-H743ZI demo board and where the core works at 64Mhz.If I bring the core to 400Mhz, (only this change), the program no longer works. Why ?Thank youAlberto.PS.I attach com...
Hello, I'm testing RTOS Message queue on STM32F7, When I try to create an message queue to send an message from Thread 1 to another thread, my data I receive in target Thread is unstable.For example, I'm trying to send uint16_t 317, but in target Thr...
Dear everyone,Here is my problem about the usbhost+MSC+Fatfs function with stm32cubemx in MCU stm32F407 and stm32L475, with a very strange issue:There is a bug about the f_write or f_f_sync, the operation and result is as followed:First test:1. ...
I tested the example in STM32Cube_FW_H7_V1.7.0/Projects/NUCLEO-H745ZI-Q/Templates_LL. It works perfectly on my Nucleo board.However, when I want to test my STM32H755 with the same code. The CM7 main blocked at while((LL_RCC_D2CK_IsReady() != 0) && ...
Our team has noticed that with a stock STM32F722RE, and 0.4V applied to the VDD pins (which is occuring in our case due to a 3.3v CAN transceiver), when 3.3V is finally applied to the chip (ie voltage goes from 0.4->3.3V), bootloader entry via USB co...
For PTP implementation in STM32F427 we have decided to use PTPd stack but I am not able to understand what is the use of Ethernet PTP target time high and low registers in achieving time synchronization.
We' re planning to implement ST-Link (USB to SWDIO) HW design using STM32F103CBT6 microcontroller. This HW design is similar to any STM32 Nucleo board's ST-link HW design. What I understood is STM32 controller will be having default UART bootloader ...
