I went through all possible data sheets I could find did all the required things but my Nucleo still won’t be programmed with uart.

I have put boot0 on VDD pin next to it. For confirmation I also put PB2 (nboot1) on ground next to it.

I tried powering the nucleo through both the USB as well as an external supply (E5V) and switched to e5v.

I reset the controller to try programming.

I’m using an FTDI, connected the Rx, Tx to the USART1 (PA9, PA10) and Gnd from FTDI to the Gnd of Nucleo
I connected my Rx, Tx and Ground of my UART to usb (which I checked with the nucleo by programming a UART program through st link and it works)

I am using St flash which says there was no communication

and stm32 programmer says it timed out for the com port

i even checked that there was no read or write protection enabled and nboot1 option bits are correct by connecting to stm32 programmer through STlink

what am I missing?
