New firmware 0.9.6.b1 and Pymakr v1.0.0.b7 released + new complete docs

  • D

    Dear All,

    I'm pleased to announce the release of firmware version 0.9.6.b1. Get the new firmware here (under Firmware Updates).

    The change log is:

    • Enable SHA family functions to the hashlib module.
    • Force port #2 on lorawan_send().
    • If a socket is already connected, do the SSL handshake when wrapping.
    • Change LoRa sockopt exception to EOPNOTSUPP.
    • Correctly set LoRa socket options.
    • Remove stray character in UART output while re-configuring.
    • Correctly close SSL sockets.
    • Add the wlan.bssid() method.
    • Replace libraries with the ones built without log output.
    • Update the bootloader to match newest IDF changes. Also increase CPU frequency to 160MHz.
    • Update to the latest IDF from Espressif.
    • Correctly trace the certificates data with the GC.
    • Add the errno module.

    We also released a new version of Pymakr (1.0.0.b7), get it here.

    The change log is:

    • Fixed multiple bugs in serial and telnet communication
    • Added Light color theme
    • Fixed backspace-bug in 'pycom console'
    • Font type preference now working.
    • Fixed compatibility with git repositories in project folder
    • Fixed 7-day-update reminder on windows
    • Added options to send soft-reset on connect or when running code to preferences
    • Fixed 'QStackedWidget' popup exception

    The new docs are complete and have effectively replaced the old ones (both for LoPy and WiPy 2.0): https://docs.pycom.io/

    Cheers,
    Daniel

    Note: the initially released upgrader tools were affected by a bug. New installers are available and are identified as pycom_update_0.9.6.b1a.dmg, pycom_firmware_update_0.9.6.b1a.exe and pycom_update_0.9.6.b1a.tar.gz. The firmware version remains the same, and will be reported as 0.9.6.b1.

    @JF002 there is a new firmware, 0.9.7.b1. Can you test it and post your issue in case it keeps happening?

    I have the same issue as @rdixey : It crashed after w while (seconds) after a successful connection to my home wifi router.
    Here is what i do:

    >>> from network import WLAN
>>> wlan = WLAN(mode=WLAN.STA)
mode : sta(24:0a:c4:00:c0:52)
>>> wlan.connect('MY_SSID', auth=('WLAN.WPA2', '********************'))

I (25953) wifi: state: 3 -> 5 (10)
I (25970) wifi: connected with MY_SSID, channel 9

    ... Wait 10 seconds

    This a brand new Lopy, updated to the "new" 0.9.6.b1 firmware:

    Any idea?

    Additional info:
    I have a second new LoPy that i did not update and it connects to the WiFi network successfully using the code in the guide:

    uos.uname()
    (sysname='ESP32', nodename='ESP32', release='0.9.0b', version='8785822 on 2016-10-06', machine='LoPy with ESP32')

    import machine
    from network import WLAN
    wlan = WLAN(mode=WLAN.STA)
    mode : sta(24:0a:c4:00:b9:54)

    nets = wlan.scan()
    for net in nets:
    ... if net.ssid == 'DixeyLAN_WiFi':
    ... print('Network found!')
    ... wlan.connect(net.ssid, auth=(net.sec, 'cbcd062459'), timeout=5000)
    ... while not wlan.isconnected():
    ... machine.idle()
    ... print('WLAN connection succeeded!')
    ... break
    ...

    Hi Daniel,

    I received new LoPy yesterday. Using Ubuntu 16.04 / ttyUSB0 I was able to complete the update to firmware version 0.9.6.b1.

    uos.uname().release
    '0.9.6.b1'

    Then when attempting to connect my LoPy to my WiFi router it receives 'Guru Meditation Error of type InstrFetchProhibited occurred on core 0.' Does a dump and reboots.

    What is the cause of this?

    I have tried multiple times with the same results.

    I do not expect this to happen since I am following the guide exactly.

    import machine
    from network import WLAN
    wlan = WLAN(mode=WLAN.STA)
    nets = wlan.scan()
    for net in nets:
    ... if net.ssid == 'DixeyLAN_WiFi':
    ... print('Network found!')
    ... wlan.connect(net.ssid, auth=(net.sec, 'cbcd062459'), timeout=50)
    ... while not wlan.isconnected():
    ... machine.idle()
    ... print('WLAN connection succeeded!')
    ... break
    ...
    ...
    ...

    @PCA does it crash if you boot in safe mode? (https://docs.pycom.io/pycom_esp32/pycom_esp32/general.html?highlight=safe boot#boot-modes-and-safe-boot)

    What are your main.py and boot.py doing?

    Dear Pycom Team,
    update successful to 0.9.6.b1 on my LoPy.
    But crashes a few second after the end of the boot process....

    Hello Daniel, machine.freq() returned different values. But I have rebuild the code afain, and now it seems to match. I might have uploaded appimg.bin only in the first test with ftp, and not used "make flash" via USB.

    @robert-hh github is up to date with the latest release... what makes you think otherwise? Please also update the IDF (https://github.com/pycom/pycom-esp-idf) if you are having compilation errors...

    Cheers,
    Daniel

    Dear Pycom team,

    the 0.9.6.b1 update looks ok. But would you mind to keep the git repository in sync with that? I'm using a slightly modified configuration of the firmware.

    @Roosted, the Linux tool is meant to be run from the shell script, but thanks for the report, now is also fixed.

    The problem does also occur on Linux!
    Just not when using the 'update' shell script - but it does brick when installing with the Python gui...

    We confirm that the initially released upgrader tools were affected by a bug. New installers are available and are identified as pycom_update_0.9.6.b1a.dmg, pycom_firmware_update_0.9.6.b1a.exe and pycom_update_0.9.6.b1a.tar.gz. The firmware version remains the same, and will be reported as 0.9.6.b1.

    As I mentioned in a previous post, I can confirm that there is a bug in the 0.9.6.b1 firmware. In case you want to downgrade and don't have the installer anymore, the download link now points to the version 0.9.5.b1 until further notice. Sorry for the inconvenience and thank you all for the support.

    Edit: fixed, see note on initial post of this thread
