I am trying to set up SMPS power Regulator for low power operation. I am using Nucleo-U575ZI-Q board. I set the bit in CR3 register but bit in SVMSR is not being set. Do anyone have idea what can be wrong? Is there something that I am missing?
By mistake, I ended up setting PA14 (SWCLK) as an input GPIO. Didn't catch the mistake until after the MCU had already been flashed. So, after that I can't connect to it anymore using ST-Link.Since I'm using a STM32G030F6 (TSSOP-20) chip, for this ch...
Hello, I recently purchased the EVSPIN32F0601S3 board and tried debugging via onboard ST-link, debugger could not connect with the main IC. I then connected the AC supply to the board, on turning on the supply the board just blew up. Kindly help me t...
There is no dedicated VDDUSBXX power pins on STM32H743VIT6, and I am quite sure with VDD=1.8V ,the internal USB FS PHY will not work properly. But what about the ULPI port? Will it works fine with VDD=1.8V? I use USB33010c as the external usb hs phy...
Hello, I have found out that connection from transceiver pins CAN_RX and CAN_TX are connected to CAN_TX and CAN_RX.I mean :from CAN transceiver to stm32f105CAN_RX -----------------------------> CAN_TXCAN_TX------------------------------...
Hello,I have stm32h757i-eval board here. I've used stm32cubeprogrammer to edit OB where I've unselected M7 core from booting and left just M4 selected. This was done in intention to boot just M4 core and leave M7 core halted.When I modified OB this w...
Hello, Im trying to power this board and sensor with 30mA power consumption @ 5V with 5V output of the board. What im noticing is the board is not capable of mantaining the voltage with this light consumptions. It starts at 4.7-4.8v with nealy 0mA co...
Hi allI tried to flash the code stm32f469i board i am getting this error please check below,IDE i am system workbench stm32.
I have a device that needs I2C and several GPIO from the discovery board, I found all the signals on P2 (STMod+) connector on my discovery board. The connector itself is designed to connect STMod or an other custom board to the discovery board. In my...
