Hii,
I am working with stm32f100 series microcontroller, where I am having issue with NRST pin, I have connected a capacitor of 0.1uF(also tried 10uF) between NRST pin and ground. Microcontroller has an internal pullup. and it is showing 3.3V at the terminal which is correct. but after connecting the programmer, when I am trying to load my program, there is a sudden fall in voltage at NRST(checked with oscilloscope) for just a millisecond. and this is disconnecting my board with the programmer. I am using STM32CubeProgrammer. how to resolve this.
I have not connected the WDG circuit to NRST.
The error I am getting , I have attached below.
