Resolved! Which software to be used when using Nucleo board as a debugger to an external board as SWD?

I want the Nucleo board 303RE to act as a debugger for my external board. Two boards have an individual 3.3V supply so the ground has been made common. Other Hardware connections are below. Since CUBE IDE doesn't allow to flash Bin files using ST-LI...

I have a question regarding the STM32L083CZT6 microcontroller. I have designed a custom board using this microcontroller, but it's not working!! Do you have any tips?

I have tested the microcontroller with different boards and all have the same problem. I have noticed that the voltage across the NRST is 0V, which I think means that the microcontroller is damaged (There is no short circuit in the system). I have co...

Resolved! LSE clock is off by 5% on Nucleo-L4R5ZI

Hi, I made a minimum CubeIDE project for a Nucleo-L4R5ZI. It clocks the RTC from LSE using the X2 quartz (NX3215SA-32.768kHz-EXS00A-MU00525) and outputs a 512Hz calibration signal on PC13. The output frequency is only ~492Hz which is a deviation of ~...
