Hi, I need to create a system for which it is possible to update the firmware remotely.My system communicates with a serial port (RS422) with a PC, and through this serial I would also like to update the firmware. Obviously without moving the BOOT0 p...
Hello, I'm building a communication between two devices an Arduino Mega 2560 and STM3210E-EVAL. For the communication I need to use RS232. In between the two devices I use the MAX232. I got it working one way where the STM32 sends 1 byte to the Ardui...
I am using STM32L496ZG to interface ISSI IS29GL064-70TLET nor flash by using HAL library. I used CUBE MX to generate the code and running code on Keil compiler. I am able to detect device ID, write and read block. But unable to erase data. I have use...
Hello.I may be on a fools errand here. I have a STM32U5A9J-DK kit obtained by work, for work. I work for a medical devices company and I get to decide what hardware is used in one of our main medical telestration products. I have endless hardware exp...

When using the STM32F103 series, it is occasionally found that the content of some flash addresses will be automatically written as 0xFF when powering on.and sometimes it's written as 0x00.I want to know why does this happen? or under what circumstan...
Hi,i Pin PC8 is configured as GPIO, but unfortuately, after execute following codesHAL_GPIO_WritePin(GPIOC, GPIO_PIN_8, GPIO_PIN_SET) andHAL_GPIO_WritePin(GPIOC, GPIO_PIN_8, GPIO_PIN_RESET) , the pin status didn't change, always keeps in High status...
Hi All,I'm starting to get familiar with the STM32 Series of Microprocessors and I'm completing some exercises using a mixture of direct writting to peripherals and low level ST libraries using the CUBEMX to get familiar with the chips. I'm using the...
Hi, I'm using STM32G474RET6 for development.When I debug code by SWD, the download verified successfully.But it will be suspended at HAL_Init() and show an error is Break at address "0x1fff5048" with no debug information available, or outside of prog...
Hi,I am an absolute beginner in STM32 ecosystem. This is my first time programing an STM32. My MCU is STM32F756VGH6 in TFBGA100 package. I wrote a simple led blink program and encountered a problem while trying to flash the MCU (got some kind of erro...
