I just received 2 STM32L053 Discovery evaluation boards. Is there a demo preloaded on the board? What is it supposed to do? After I plugged power into USB ST-LINK, the first board cleared the display while the second did not. Then the boards do nothi...
We are using STM32F427VGT6TR, in our project. We found the MCU went to "Level1- read protection" while performing a hardware debugging. We are not able to disable level-1 and put the MCU into the Level-0. We are able to connect the MCU using STLink a...
Hello there,I have a STM32F303 chip and use ST-Link V2 to update the FW of the chip on my board.If I uses STM32 ST-LINK Utility(V4.6.0.0) to update the FW of the chip, then it's working fine:after updating FW and after power cycle, the chip on my boa...
I am trying to flash a STM32L053 Nucleo using UART pins and so far, I pull boot 0 high by adding a jumper across boot 0 and VDDI power the controller with E5V optin and connecting an external poer supply to the E5v and GNDIf I connect the USB to the ...
I'm using the Nucleo-32 on another project and have found the schematics in UM1956 helpful in certain debugging scenarios, as well as a kind of reference design to help me get started on my own board design.
i'm using the stm32u5 iot eval board BU585IIO2A and want to use USART3 on Arduino connector CN14i successfully got the PWM working on PIN7 of CN14 but i fail to get anything sent / received on UASRT3 (Pins 1 and 2 of CN14)are there any hints / sampl...
I have PCB made for STM32F103C8F46 with the attached schematic. At first I use ST-LINKV2 debugger to connect to the target. It connects successfully and able to flash the code as well. and it works well. But after some-time (like 5-10minutes) of keep...
Hello, in my current project, MCU is using STM32F446ZET6 and emulator is using ST-LINK/V2-ISOL. I am trying to connect with JTAG, but when I debug with CUBEIDE, Target no device found appears. I checked the Vcc (1pin) of the connector, but before con...
Hi,I have three STM32H7B3IDKThey all have different serial numbers.I am running two boards OK one on the old STMStudio gathering data the other connected to CubeIDE.I can connect the third and can scan for it in CubeIDE and CubeProgrammer, but when I...
Hello, My company recently rolled 20 boards with STM32G030's. We have a lot of experience working with the G070 but not the G030 MCU. We're having a tremendous amount of trouble programming these. The MCU will not connect with either CubeProgrammer o...
