Resolved! VCAP in hardware design
I have got a custom PCB using STM32F4. I don't have any capacitor connected to the VCAP Pin and I wonder if this is necessary or not. Which is the use of VCAP and do I need to add it to my design? What can I do to solve my problem of no having one if...
Resolved! Regression of ST-Link_gdbserver 1.10 compared to previous version ?
For a long time I have been using the following setup:two STM32H7 eval boardsone gdbserver session for each STM32, with a different portremote debugging on the two STM32I just switched from STM32CubeIDE 1.0 to 1.10.1 and now I have this weird behavio...
LVDS devices
I have two devices I am looking to integrate with STM32 MCPUs. One is a Honeywell HG1125 IMU and the other is an WFF93 Encoder.Both devices use LVDS signalling. I don't know much about that signaling at this point, but I am taking a broad stroke fi...
Hi, I would like to ask if it is possible to use NUCLEO-F042K6 to program another STM32 MCU via embedded ST-LINK? Thank you. Best regards, Ondrej
I see from the schematics in datasheet UM1956 that there is a reserved CN2 connector with SWDIO and SWCLK, NRST can be found on CN3. But I do not see any jumpers to switch whether ST-LINK is used to program on-board Nucleo MCU or an external MCU like...
STlinkV3 usability of the STM32G4 Nucleo-32 board (MB1430)
HelloI may have misunderstood:By cutting some SBs offand soldering on CN2 the embedded STLinkv3 can be used externally ? meaning on other targets/boards ?
Resolved! I'm trying to connect to a custom PCB made using an STM32L552ZET6Q using SWD and Cube Programmer, but I keep getting the "No STM32 target found!" error.
I've gone over the hardware with a multimeter and all the pins have the right continuity, I've checked the design against the Nucleo-144 L552ZET6Q schematic and it checks out so far, and I've also checked the connections to the ST-LINK/V3 pins I'm us...
HyperBus (OctoSPI) length matching
I'm doing PCB layout and I'm trying to assign pins for the HyperRAM (HyperBus) that will give me the simplest layout.The app note for the RAM IC has extremely strict length matching requirements. For example, matching between the data lines all have ...
STM32F4 Hardware for external clock
I want to develop my own PCB using STM32F4. I want to use one external clock (16 MHz). I wonder where I have to connect the clock: OSCIN32-OSCOUT32 (pins 3 and 4) or OSCIN-OSCOUT (HSE) (pins 5 and 6 in STM32F446RET).I can see in the development board...
Resolved! How to connect VBAT on STM32H7 when not using a battery?
Section 6.4.4 of RM0433 is the only place I could find that says what to do with VBAT rail when not using a battery. It says the following:If no external battery is used in the application, it is recommended to connect VBAT externally to VDD through ...
