Best Practices for Debugging Intermittent MCU Freezes on STM32
Hi everyone,I am working on an STM32-based project and occasionally facing an issue where the MCU freezes during normal operation. There’s no hard fault or obvious error, and the issue doesn’t happen consistently, which makes it harder to trace.So fa...
Stm32 SPI Slave Incorrect Data Receive or SPI going out of Sync from Master
Hello Community,I have Several Query Related to STM32F439 Microcontroller SPI 6 Slave DMA Mode,Let me Explain the Scenario , we have Custom Board Build Around STm32F439 micro-Controller and using HAL Stm32V27 Library Version.so we are Communicating w...
Accessing Wrong Flash Address and Got the Hard fault error after hour of Continuous Run.
Hello Community,I got one Stranger Problem, as i was Debugging one Hang Issue there i Got in user Application we are Storing Application Checksum in Flash Address 0x0801FF0 and Accessing and Reading Back from 0x081FFF00.So in CBIT Test I get Result P...
STM32H755 user button interrupt in both MCUs
Hello everyone, I would like to ask if it is possible (and if so, how) to make both m4 and m7 get an interrupt made by the user button in in the nucleo board, since the only Pin Context Assignment options on CubeMX is either m4 or m7. Do I have to do...
STM32H725 internal tamper detection
Hello,I am trying to figure out how to configure internal voltage monitoring use the internal tamper detection to clear the RTC when an undervoltage condition occurs. My understanding is that you have to enable the backup regulator and enable monitor...
USB-PD attention callback never get's triggered?
Problem When i call * USBPD_PE_SVDM_RequestAttentionI get a OK message response but the callback never gets called. * USBPD_VDM_SendAttention Curious to know if there's any good way to debug this? Current debugging stepsI have a STM32G0-Disco board...
ST-Link/V2-1 is not getting detected
Hi,i am working on STM32cubeIDE for STM32G071RB nucleo-64 dev board with windows 11.i have a ST-LINK/V2-1 programming and debugging tool is integrated into the Nucleo as shown below image.To power the board, I connect the STM32 Nucleo-64 board to m...
Resolved! UART & DMA overrun error
Hi all.I'm working on a project where my MCU (STM32H755) communicate with a device via UART at 921600 Bauds.Here some details about the environment:The device sends constantly, each second, a log at 921600 Bauds. The MCU sends at same speed some comm...
re YouTube tutorials a good way to really learn STM32, or do they create bad habits?
Hi everyone,I’ve been working with STM32 for a while now (mostly CubeIDE + HAL), and like many others, I’ve watched a lot of YouTube tutorials to get started and solve specific problems. Some channels explain things very clearly and are great for qui...
