• Exact steps to cause this issue
  1. First I registered to pybytes : https://pycom.io/products/software/pybytes-3/
  2. Then, as requested I updatedwith "ONLINE FIRWARE UPDATER"
• What you expected on Windows 10, using ATOM 1.54 and Pymakr 2.2.0
  • was to connect properly to my LoPy4
• What happened instead
  • I got : "Connecting to COM5... " on ATOM/Pymakr
  • Led 'LED' is 50% ON the color is Orange
  • led 'USB' is ON the color is Green

Thank you for your help

Got the same issue with FiPy + exp board 3.1. I have connected several units with pybytes before but now it is impossible. Downgrading firmware on the pycom board does not work.

Have you tried pushing the safe boot button when resetting the device? Are you able to use the erase_all option with the CLI firmware updater?

[Ztubben]

Yes I have. Unfortunately none of those methods work.

[Inzemon]

Agree, same for me.

I guess if I was able to (re)install the previous version, it'll be fine. But The version I got (LoPy4-1.20.3.b3.tar.gz) is not that easy to install. Do you have some "How-To" you can share?

I have also send a request (including the log file) to Pycom and 7 days later no reply but a confirmation request.

After reviewing the documentation, I missed up the update firmware for the expansion board. I did it successfully, then updated again the Device "Lopy4", to finally got the same issue on Atom with Pymark : "...Connecting to COM5..." Safe boot -> no effect Reset got same log as previous The Main LED is blinking BLUE The USB LED is Green The "LED" LED is 50% bright orange.

So no access to my USB port even after these updates. I'm stuck, as I can't enter python scripts.
