UART Bootloader

[Abijith]

I am trying to flash the memory of the STM32-L43KC (Nucleo-32) MCU with the UART Bootloader. 
I have connected the TX and RX pins of the board to FTDI USB-RS232 connecter. 

To boot from the system memory, I have also configured the option bytes accordingly:

nBOOT0(bit) = 0, nBOOT1(bit) = 1 and nSWBOOT0(bit) = 0

 

But I am unable to use the Flash Loader Demonstrator and I get an error message saying Boot Loader cannot be started.

 

FYI, the STM32-L432KC doesn't have BOOT0 or BOOT1 pins attached to the board to access unlike other STM MCUs.
