Hello ST community. I'm using STM32F401RDT6 microcontroller which is powered during the day by a solar panel (power regulators converts the panel's voltage to 3V3). The MCU uses its internal RTC for logs and the issue is to keep the RTC running fro...
Debug project with external loader Hi all,I have a project with an external loader and I didn't succeed to enter to debug and download the hex (sometimes is and sometimes it is not it didn't consistencyi didn't understand if it's the st programmer or...
Hi, can someone refer to the above MCU reference. This is my first time using the STM32 MCU chip on my embedded system. My question regarding the power up/down phases concerning specifically on STM32L433CCT6 IC ... Is it a must and critical to use so...
I have 4 Discovery boards:STM32F769I-DISCO, STM32F469I-DISCO, STML4R9I-DISCO, and a STM32H747I-DISCO boards. The H7 and L4 boards came pre-loaded with the demo firmware. So I downloaded the ST provided demo hex files for both the F4 and F7 boards. Us...
Hi Engineers,I am kinda new to the STM32 MCUs. I have a custom PCB powered with STM32G031F6P* TSSOP20 MCU. so on the PCB, I have a PIN "SWCLK", "SWDIO", GND, and VCC for programming. NRST is pulled HIGH. the strange thing is that BOOT-0 is on the sam...
HelloI have recently acquired a B-L475E-IOT01A2 IoT node, which has an integrated SMT32L475VGT6 MCU microprocessor.I have installed the STLINK V2 driver and tried to connect to it via a microUSB type B cable to the USB_STLINK port (CN7), with jumper ...
Hi,We are using STM32H743 microcontroller in our project. We are getting the hard fault exception during accessing of internal flash memory.We verified the memory location in ST link utility and STM32CubeIDE.In ST Link utility it is showing "10:50:08...
I would like to use the otg_fs_vbus interface of the STM32F7508 Discovery to plug in a USB stick. When I activate VBUS in CubeMX, the board no longer boots up. The reason for this is that pin PA9 is used for the ST link (UART1) and the vbus. Both at ...
