@robert-hh ah yes, exactly, in the 16 second time of startup i read some file: planning.txt for see if startup is needed for the device, wifi_name.txt for the device SSID etc... Not all for the code loading!
This issue is discussed on GitHub here
@pmst It's not yet possible through the firmware updater tool but if you have Python3 + PySerial on your PC you can update through serial. See https://github.com/pycom/pycom-libraries/tree/master/lib/sqnsupgrade for more details.
Let me know if you have any issues.
@xykon Works now with the new 1.14.2. Thank you!
That worked perfectly.
That is correct, the 1.17.0.b1 upgrade is for the LoPy. You do not need to
ever upgrade firmware for the expansion board 2
@robert-hh Hi Robert, You gave the point I was not using the reset button but powering off and on.
After using the reset button I had the ready to upload and now is upgrading.
I don't know of any alternative, but have you tried it on another computer?
