Resolved! STM32H755 LwIP FreeRTOS StackOverflowHook - Wrong configuration?
Hi everyone,I try to impement the LwIP Stack on my NUCLEO-H755ZI-Q Evaluation Board. I want to use the M4 core for the ethernet communication.Unfortunately it results always in a StackOverflowHook if I connet with "Hercules" TCP Client and send a str...
Can I operate a DSMPS when writing to FLASH from the MCU?
In my custom board, the STM32G4 is regulating the voltages on two converters, a buck, and an inverting buck. The peak current mode control used generates an interrupt every 5us for some processing, including current limit detection.Currently, the MC...
Resolved! stm32 C Global Variables do not have their initialized values
Was working on an EVAL board stm32G474RE which has FLASH of 512K and RAM of 128K. Everything was working fine on the EVAL board. Now we received the actual hardware which is a stm32g474CBU. Very similar to the EVAL board but the FLASH 128K and RAM of...
Problem with the ADC measurement with DMA and RTC
HII have a problem. I want to measure 4 channels of the ADC every 20 seconds (this is more time but for now it is like this for testing) through an RTC interrupt, then print by the serial terminal.What happens is that it shows me the reading every 20...
Datasheet and CubeMX not matching with pin alternate functions
Hi,I have a project involving an STM32F030C8T6 MCU. The datasheet says that pin PF0-OSC_IN and PF1-OSC_OUT have I2C1_SDA and I2C1_SCL as their Alternate Functions. When I go CubeMX to select them as such, it doesn't give me an option to do so, even t...
Nucleo L476RG at 1.8V
I want to run a Nucleo L476RG at 1.8V at first glance it looks possible with a few caveats.according to the schematic (C03)https://www.st.com/en/evaluation-tools/nucleo-l476rg.html#cad-resourcesThere are two regulators I need to be concerned withU4 w...
ST marking name
Hello. I bought a STM32G474MET6 chip on Alibaba and the supplier claims that the chip is original but I have some doubts. Here are the attached images he sent to me. Can you please check that and confirm if it’s genuine please ?
CoreDebug->DEMCR default value
Hi,MCU - STM32H7I have noticed that the CoreDebug_DEMCR_TRCENA bit in the DEMCR register is set by default if a debugger is connected. But, I need to enable it explicitly (as shown below) if the debugger is not connected. CoreDebug->DEMCR |= CoreD...
EEPROM emulator corrupts STM32G431KBU6 program
Hi all,We deployed a lot of devices that have a STM32G431KBU6 controller.It basically has a foot switch to turn on/off a 12v DC motor and a rotary switch to control the speed.We use EEPROM emulator to save the speed setting.If speed setting is differ...
