I am seeking to activate the DFU mode in the B-L072 Discovery Module using the Murata CMWX1ZZABZ-091 module. https://www.st.com/resource/en/user_manual/dm00329995.pdf
I have kept BOOT0 pin to HIGH and connected a USB cable to the CN11 USB connector. But STM32prog does not detect the DFU bootloader. Also the device manager does not detect the board. Tried using DFuse also, then uninstalled that and started using STM32prog and did all as asked under the STM32prog PDF UM2237. I also shorted the SB16 & SB15 points to enable the USB DP-DM connection.
Also, uploading code by USART is also not working. Connected an external USB-UART to PA9 & PA10. The USART also does not connect. 😞
What am i missing here? Any help would be deeply appreciated...
