New firmware release 0.9.3.b2

[MainSheet]

Hi,

I just updated 2 LoPy's to 0.9.3.b2. After updating I have not been able to communicate with either using telnet, ftp or PyMakr .
I tried all 3 safe boot modes on both devices, no luck. Every once and a while I will get a >>> prompt but within seconds I get a connection error.

Otherwise, they seem to be working, both a updateable, heart beat led is working and when in safe boot mode they both come up as APs, and I can get a connection to them when they are in AP mode.

@MainSheet Can you post the output you get on the serial port?

[MainSheet]

@Xykon most of the time I get this, :

Connecting to a Pycom device...
Error while communicating with the Pycom device! (click to attempt to reconnect)
Connecting to a Pycom device...
Error while communicating with the Pycom device! (click to attempt to reconnect)
Connecting to a Pycom device...
Error while communicating with the Pycom device! (click to attempt to reconnect)

Occasionally there will be a normal connection in between but it only stays up for a few seconds.

few other details
Tried PyMakr in Windows10 and Ubuntu .
can't connect with Putty or Filezilla.
PyMakr is 1.0.0.b6

Thanks for the help
Steve

@MainSheet Can you check with putty in serial mode? Set connection type to Serial, adjust the Serial line COM port number and set a speed of 115200. Make sure PyMakr is closed and click Open

Then press the reset button on the WiPy2/LoPy and post the output you get.

When you post the output please surround it with ``` before and after the output.

@MainSheet For Unit1 it seems either your boot.py is missing the code for the serial REPL or it contains an error which prevents it from being executed. You should however be able to connect to it through Wifi and telnet / ftp to 192.168.4.1. You should check that your Wifi settings are correct when connecting to the module via Wifi. Can you try to ping 192.168.4.1 to check if your network connection to the module is working? You should at least be able to use putty in telnet mode to connect to 192.168.4.1. You can then run execfile('boot.py') to see if there are any errors in your boot.py.

For Unit2 this seems to be able to connect to your Wifi AP. Check this one also with ping 192.168.0.118 to make sure it is reachable over the network. You should then be able to telnet & ftp to 192.168.0.118. Make sure that your Filezilla settings are correct as described here. In putty make sure you choose telnet protocol and not the default ssh.

@Xykon , First, thanks for all your help, I have both units working now.
Both units had zero byte files in the /flash folder. I believe this was a result of using the PyMakr sync project button, as that was the last tool I used to upload files.

I still can not get the PyCom console in PyMAkr to load the REPL prompt. PyMakr is configured on COM4, the same port I used successfully for putty (serialmode).

Connecting to a Pycom device...
Error while communicating with the Pycom device! (click to attempt to reconnect)
Connecting to a Pycom device...
Error while communicating with the Pycom device! (click to attempt to reconnect)

I also configured PyMakr for 192.168.0.118, still could not load the REPL prompt.

Hi,
I am on macOS Sierra and when I downloaded the newest version of the updater, I was not able to launch it.

I debbuged it by launching it on the terminal and it says the file lopy.py did not find the folder 'firmware'.

I took a look into the code and in the function __establishFirmwareVersion, line 426, I had to change bins = os.listdir('/firmware')by bins = os.listdir(HERE_PATH+'/firmware').
Now it works correctly.

[Xykon]

@MainSheet I only used PyMakr very briefly (it keeps turning the awfully bright LED on and it's very annoying having to turn it off manually all the time) but it was working with the LoPy and the latest firmware.

The only reasons I can think of why PyMakr can't connect to the serial port is that something else is blocking the COM port or there is something in your boot.py/main.py that's causing PyMakr to fail. You could try import os; import machine; os.mkfs('/flash'); machine.reset() to restore your flash memory to firmware defaults, it will re-create a boot.py with nothing but the code for serial REPL along with empty main.py and sys, cert, lib directories.

As for not being able to connect via the network, did you try ping 192.168.0.118 from the command line? Did you try putty in telnet mode and FileZilla with correct settings?

@matamune said in New firmware release 0.9.3.b2:

bins = os.listdir(HERE_PATH+'/firmware')

Yes! This makes the firmware updater working on the MacOs. I'm on El Capitain.

To be a bit more specific, one need to apply the fix in here:
/Applications/Pycom Firmware Update.app/Contents/Resources/src/lopyupdate.py

Thanks guys that worked.

Dale.

[MainSheet]

@Xykon I think I will put PyMakr to the side for a while, between FileZilla and putty I can do whatever I need. Your input has helped me get up to speed quickly. Thanks

[abilio]

@matamune, thanks for your observation. There is a new version of the script that takes into account your findings. It should start now :) It's available in the usual place, and the file is named pycom_update_0.9.3.b2a.dmg

[scratchrobot]

FTP still not working for me after upgrading to pycom_update_0.9.3.b2.dmg

[livius]

I do not have mac but did you checked real version it it was upgraded?

import os
os.uname()

This topic is "pinned" and is as a first on the list - but newer firmware topic exists

@liviusm, thanks for the pinned observation :)
