      I have 2 LoPy modules. one is working fine I am able to connect and program it. It is making a wifi network with ssid lopy-wlan-beac. But second module dose not seems to work. However Pycom Firmware Update utility working on it ,( i probed the usart pins and some communication is happening while running it) and shows successful message on completion.
      But when connecting to pymakr from atom ide nothing happening (no communication on serial pins when probed). It is also not showing any wifi network to connect to it. only blue led is blinking one per 3-4 seconds.

        Hi @saurrabh2205,

        Are you using an expansion board to connect to your lopy modules?

        Thanks,

        Alex

            @saurrabh2205 Have you tried booting the lopy into safeboot mode? This will trigger the LED to flash orange and boot into a firmware safe state.

            https://docs.pycom.io/pycom_esp32/pycom_esp32/toolsandfeatures.html#safeboot

            Once you've managed to get the device into this state, I suggest running the following code from the REPL:

            import os
            os.mkfs('flash')
            

            This should clear anything that might prevent the device from starting correctly.

              Thank you @bucknall, it worked after booting into safeboot mode.
