The chip model we use is STM32L496VG. Our customer reported that the machine became unresponsive (bricked) and couldn't power on after an OTA upgrade. After receiving the machine, we used STM32 Programmer to read the flash, which prompted chip protec...
Hello,I am using the STM32H745I-DISCO board for my project, which requires both TouchGFX and CAN FD functionality. However, I am encountering an issue with the clock configuration.I need to synchronize the Nominal Baud Rate to 500 kbps and the Data B...
dear ST and/or Users, we’re using STM32H743I with a requirement now to store several bytes of data in non-volatile memory. We have known-working code for the existing application, and need to be assured it is not affected when eeprom emulation code...
I'm a beginner and I don't understand the datasheet very well. Can I externally power my STM32 F446RE from the VDD pin (the one opposite E5V in the pinout)?Sorry for the banality, but I only found info for generic GPIOs.Dar
Hi everyone,I’m working with an STM32L476 and need to parse its 96-bit Unique Device ID (UID).According to RM0351, the UID starts at address 0x1FFF 7590.Reading that region with STM32CubeProgrammer gives:• 0x1FFF 7590 : 0x004A0029• 0x1FFF 7594 : 0x58...
I have a problem with an STM32H7A3 which remains stuck in SystemClock_Config. I use Keil. Any ideas please? it just remain stucked here: if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_Os...
I'm trying to learn how to use the LCD display on the STM32H745I-DISCO board.(I'm a beginner at coding, so please go easy on me!) Right now, I'm just trying to display basic text on the screen, but nothing shows up, it's either all white or all black...
I'm trying to implement a serial bit-stream input (PCM-style) on an STM32U575. I have set up an EXTI channel to capture the incoming clock signal and then I'm using the following code in the ISR to capture the data bits:__attribute__ ((section(".RamF...
Hello everyone,I'm currently working with an STM32F746 microcontroller as an SPI slave using DMA for data reception.The SPI master sends fixed-size packets of 512 bytes, and everything works fine most of the time. However, occasionally, a few bytes (...
Hi Team,We are currently working on a design using the STM32U5A5QJI6Q microcontroller in a BGA package, implemented on a 4-layer PCB. During the hardware development phase, we inadvertently omitted the external pull-up resistors on the I2C lines, spe...
