Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
How I understand from this schematics: PC8 and PD2 have pull-up resistors connected to them while the rest of them don't, this means that the rest should get Pull-up resistor in the settings of the GPIO and this will enable the pull-up resistor from ...
Hi,we have a PHY with several bootstraps. Some of them are shared with the RMII from a STM32H753 (see image below, controller is on the left).A FreeRTOS+TCP network stack is used, which, when rebooted, first does some low level inits with HAL_ETH_Ini...
Hello,We working on custom board. We using this controller STM32745IIkx. In JTAG we connect the USART1 port, but there is pin mapping issue, so I am unable to use USART1.So instead of UASART1 can I use USART2.I am sharing its schematic THE VCP_TX and...
Starting server with the following options: Persistent Mode : Disabled Logging Level : 1 Listen Port Number : 61234 Status Refresh Delay : 15s Verbose Mode : Disabled SWD Debug : Enabled InitWhile...
Hello, Could anybody please look at the circuit, and if it is correct.I am not sure if C5 is necessary to be there.Thank you.
I fired up CubeIDE again after a while, it updated from v1.4 or so to 1.8 now.When I was about to debug, it offered to update the firmware of my ST-Link V3 SET.It claimed that was successful.When I then wanted to debug, it claims there is no target.I...
Hello,For a project, I created a PCB with an STM32F411 using a 10pin JTAG port for SWD programming.I tried to connect my card using the ST LINK V2 box and the ST Link utility software but I get the following error:The st link works because I can prog...
Maybe is a hardware problem since the microcontroller is on a custom board I designed. The problem is the following: The microcontroller only runs the program the moment I load the code, if I reset it or power up the board after a power-off it does n...
I'm trying to understand the benefits/tradeoffs of the "Direct SMPS supply" and "SMPS supplies LDO" options for the STM327H (red and blue options in the attached figure). Since the LDO adds an extra source of power loss, and the SMPS can supply all d...
