Finally after a long struggle, I was able to get into the system memory by changing to CP2102 ttl wire. Now I have another problem. Any solution to fix this? The PCROP_PDP bit is unchecked also.

May I know where is the PH3/BOOT0 pin on the STM32L432KC board? I don't see any GPIO pin for that. It is connected to the F103 chip onboard but how do I use that?

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 accordi...

This is regarding the UART1 and UART2. 1. I am trying to learn how UART works by communicating between STM32 and ESP32. I am able to send data from STM32 to ESP32 and it works. However, when I do the same from ESP32 to STM32, for some reason I cannot...
