      Hello,

      I'm having problems setting up my Atom Lite. I'm new to M5 hardware but I have some experience as developer. Following the M5 documentation, I tried to flash the new firmware UIFlow v1.5.3 but I get the following error:

      0_1591340699120_Screenshot 2020-06-05 at 09.04.31.png

      I found some related topics of other users having a similar issue in the past, however, none of their solutions worked for me.

      I noticed that the esptool.py (2.5) bundled in the M5Burner electron app was the root of my issue, so I tried a newer version 2.8. Using this new version I had no issues importing the module named serial.tools.list_ports.

      As the M5Burner wraps the esptool I tried to flash my Atom Lite with the latest esptool version (2.8) reusing the command shown on the above screenshot.

      Based on the above output I think that the flashing was ok, but still, I can't connect my Atom Lite to the UIFlow IDE (Online/Desktop)

      I get this error in both cases:
      Upload code failed, maybe your device is offline check it and retry

      After I reset the device I got the following output from the M5Burner COM Monitor

      Right now the atom's led is always RED

      Any suggestions on how to solve this problem?

      Thanks in advanced,
      Humberto

        you could pip install a pyserial module to solve it.

        we will fix this bug in next version. thank you feedback

        the LED always RED? which program are you use? if you want to use UIFlow . you could refer this tutorial :

          Hi @m5stack

          you could pip install a pyserial module to solve it.

          I tried that but the problem persists. As a quick fix, I just flashed it using a window virtual machine.

          the LED always RED? which program are you use?

          Yes, but after I flashed the new firmware everything is behaving well.

          which program are you use?

          It turned RED, after I tried to flash it with the newer esptool (2.8) as I showed in my initial topic

          we will fix this bug in next version.

          🤞🏻

          Have a nice day
