Resolved! STM32L433CCT6 Datasheet DS11449 Rev 6 (page 21) - Concerning power up/power down phases in hardware design
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...
Why brand new Discovery boards give me "Error: failed to erase memory" when I am just loading up the ST provided demo hex
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...
How to Program STM32G031F6P* TSSOP20 package with ST-Link V2
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...
Resolved! L475E is not recognized by my PC using STLINK [SOLVED]
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 ...
STM32H743 goes to hard fault during accessing of internal flash
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...
STM32F7508 - Problem with VBUS and ST-Link (UART1)
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 ...
Unable to connect and flash program to STM32F407(custom board)
1)is crystal is required to be used for program flashing 2) boot0 to be low or HighNote: I'm using ST-LINK V2
