STM32G0 STM32MX generated PD source application generate hardreset every 14s

Hi, We have an PD source application on our custom board with STM32G071GBU6N. We use STM32 MX to genereate a PD source application (PD Core 4.1, device 3.4.1) following steps on STM32StepByStep:Getting_started_with_USB-Power_Delivery_SourceAfter fil...

Difference between STM32CubeIDE and GDB

I'm a newbie to STM32 programming, but have 25+ years in desktop development.I've created a PCB with a STM32F042F6 mcu (based on a working design). I added pins for a SWD port and I have an LED connected to PortB1.I've used STM32CudeIDE to create a s...

Anyone else working with the Azure RTOS NetX related code for the B-L462 Cell dev board? I've got the MQTT code working and I am debugging, attempting to improve connectivity.

STM32F427 PTP Implementation

Posted on May 30, 2018 at 12:08Hi everyone,We are using the STM32F427.We have devices that need to work synchronously.So we decided to use PTP but we have no experience in this matter.I have reviewed the AN3411 document to learn how to use PTP.But I...

STM32F4 library issues fixed?

Several years ago we started a project using an F429 main and 8 F413 slaves, communicating over an SPI bus. In 2020 we stopped the project because of too many problems with ST-provided drivers/stacks, especially Ethernet/lwip and USB, and very poor F...

Using the B-L462E cellular board with Azure NetX MQTT code to connect to, publish and subscribe topics on my own mosquitto server. How can I reconnect to MQTT after the server restarts?

Code is attached. When the mosquitto server is shut down, the code loops, failing to connect via this call nxd_mqtt_client_login_set(&mqtt_client,MQTTNAME, STRLEN(MQTTNAME),MQTTPASS, STRLEN(MQTTPASS)). After failing, nxd_mqtt_client_disconnect(&mq...

Hard faults, but not really == impossible to debug

In a current PCB design, SWD debugging is very erratic. Stepping through the code line-by-line works fine, but executing multiple lines will sometimes result in an apparent crash with a call stack like0x08061300xfffffff9which doesn't make any sense f...

STM32H7 I2S DMA RX problem but not TX

HiI am stuck with STM32H743IIT I2S DMA RX ..The code is working perfect when uncommet HAL_I2S_Transmit_DMA (Line 29) but when uncomment line 31 HAL_I2S_Receive_DMA it feedback HAL_OK but do never go into the callbacks ..What can be the issue ?Best re...

What is the status of Ethernet driver of STM32F107 work with Zephyr 3.3.0 distribution with MII phy?

There are some comments in STM HAL driver code: stm32f1xx_hal_eth.c "The PTP protocol and the DMA descriptors ring mode are not supported in this driver". Can this driver work with zpehyr RTOS and the Ethernet Rx works in interrupt mode?Also, inside ...

Using NVIC to measure frecuency of a multiple pulse signal in StopMode2 is a good option?

I am trying to create a frequency meter in a STM32U575ZI microcontroller that works with ThreadX and low power consumption using the low power timers LPTIM3 and LPTIM4, as well as an interrupt using EXTI 14. In summary, I use LPTIM4 to count input p...
