New Beta Release v1.20.3.b3

  • P

    Dear Pycom community!

    We have a new Beta release available: v1.20.3.b3.

    This firmware contains major upgrades of the IDF and Micropython and a range of changes to Pycom specific features. The IDF and Micropython are foundational pieces of our firmware. The IDF is provided by Espressif, the makers of the ESP32. Compared to the latest v1.20.2 releases this new beta firmware brings the IDF from v3.3.1 to v4.1. The Micropython version is upgraded to version 1.13.

    This is a Beta release which means, we do not advise you install this on production devices. Some reports we have received describe stability improvements, while others point to some problems which still need investigation. Some known issues are listed at the bottom.

    We would love to hear your feedback! What works better for you? What has regressed compared to the regular v1.20.2 firmware?

    Changes:

    • IDF v4.1
    • Micropython v1.13
    • LoRaWAN 1.0.3 (Class A& C)
    • Support for new regions (CN779, RU864 and KR920)
    • BLE Mesh
    • Reworked Coap with DTLS support
    • ESP-NOW
    • WiPy2, SiPy, and LoPy1 and are not supported anymore since they only have 4MB flash.
    • WiPy3, LoPy4, FiPy, GPy, W01, L01, L04 and G01 are all supported
    • improved wear levelling on LittleFS (thank you @robert-hh!)
    • bugfixes

    This firmware also contains improvements to the OTA (over the air) update functionality:

    • the main firmware partition is larger than before
    • there is a small 'factory' firmware partition, just enough for OTA
    • support for compression and
    • support for differential updates

    The documentation and infrastructure (software server, installer, etc) for these OTA features will be released separately.

    Known issues:

    • Soft reset (Ctrl-D) causes core dumps
    • No OTA support from Pybytes yet
    • No ethernet support on Pygate yet
    • Pygate on Gpy and Lopy4 seems to run out of memory. On Wipy there is just enough memory - For testing with wifi one could flash the Wipy firmware.
    • Secure boot is not supported

    You can

    Hello all!

    This release doesn't appear to be changing the LoRaWAN mac version to 1.0.3, on a LoPy4. Update performed with Pycom firmware updater tool (not self built).

    >>> import os
>>> os.uname()
(sysname='LoPy4', nodename='LoPy4', release='1.20.3.b3', version='v1.11-92f2b22e on 2021-04-19', machine='LoPy4 with ESP32', lorawan='1.0.2', sigfox='1.0.1', pybytes='1.6.1', pygate='1.0.1')
>>>

    Could it be that the name was not updated, though the firmware still tries to support 1.0.3?

    If this feature requires me building a more recent beta version, would consider it. Could really do with this for testing.

    Thanks for any pointers.

    @peterp is this beta worth testing or has the code base moved on too far?

    Yes. At this moment, you might test three different options. It could be that either one has their own pros/cons:

    • stable FW based in IDF 3.3.1 - 1.20.2.rX for the latest X (right now 1.20.2.r4)
    • beta FW based on IDF 4.1 - 1.20.3.b3
    • alpha FW based on IDF 4.2.1 - 1.20.3.b4

    I need to integrate Ulab but the available 1.20.2 with ulab has LTE issues

    I haven't looked into this at all, but I find it surprising that there is a relation between ulab and lte.

    @Jean-Ferreira All I can tell you is that new MP and IDF versions are being worked on, but I can't give you an ETA

    @peterp can you please provide an update on this? I need updated IDF and MP to stay with this hardware platform but feedback and progress has been slim on the ground the last few months.

    There have been no release candidates or beta improvements.

    Hi @peterp,
    Any updates on this release?
    I see that there hasn't been that much activity lately, and I am eager to include uasyncio in my project : )

    @peterp
    You now implemented LoRaWAN 1.0.3 (Class A& C). Does that mean that the MAC command “DeviceTimeRequest” can now be used to synchronize the real time clock of an end device? (see https://lora-alliance.org/resource_hub/lorawan-specification-v1-0-3/) If yes, how? Or where can I find that information?

    I've tested new Beta Release (again thanks for the update)

    Regarding ULP question, sadly is not included here but check out my post ULP Testing (pycom firmware with ULP support) as I've managed to "copy" micropython ULP part and integrated more or less on pycom firmware.

    Regarding LoRa DeviceTimeReq, DeviceTimeAns not tested, but checking the code I think is not supported yet.

    Side note, the Beta release requires to flash entire memory: differential update doesn't work and it complains with wrong size.

    Regards

    @peterp said in New Beta Release v1.20.3.b3:

    Maybe some git submodule stuff?

    There are sometimes warnings when changing the branch, that directories cannot be removed because they are empty. In combination with the unneeded lib includes for -L$(ESP_IDF_COMP_PATH)/esp32/lib and -L$(ESP_IDF_COMP_PATH)/bt/libin Makefile line 182ff that could have cause the trouble for my old repository. But I do not understand why that happened too with the new cloned versions of esp-idf. Maybe some caching of paths.

    @peterp said in New Beta Release v1.20.3.b3:

    Soft reset (Ctrl-D) causes core dumps

    Commenting out 'uart_deinit_all();' on line 381 in mptask.c lets the code survive soft reset.
    So maybe the delay is to short for the 'MPY:soft reboot' message to get sent.
    Yup: Increasing the delay at line 379 to 50000 does the trick.

    Awesome @robert-hh I'll check that today!

    @robert-hh said in New Beta Release v1.20.3.b3:

    two additional lib directories in components/bt and components/esp32. But HOW did they get into the fresh cloned esp-idf? They are in the linker search directories, hmmm.

    Maybe some git submodule stuff? I recall some trouble when doing a git checkout that is "too far". E.g., git clone idf3.3.1 and then git checkout idf4.1 would lead to some messed up git submodules and it was just easier to make a fresh git clone from a branch that is just a few commits away from the IDF_HASH without any major changes to submodules and then you can git checkout IDF_HASH and have all the submodules correct.

    Did those two directories not show up with git status? I'm sure there is a " correct " way with git to do this checkout in any existing clone, but I couldn't figure it out and just settled on a new clone from a "close" branch as shown above.

    @peterp Building in a up-to-now rarely used mint linux virtual machine worked. So if have to tell now what is interfering with the other build process.
    Edit: copying back the pycom-esp-idf directory from the virtual machine to my primary machine worked too. So: Why did the esp-idf not install properly?
    Edit2: Found the culprit: two additional lib directories in components/bt and components/esp32. But HOW did they get into the fresh cloned esp-idf? They are in the linker search directories, hmmm.

    @robert-hh you must generate an SSH key in your machine:
    Generating SSH key

    Add the key to your SSH Agent
    Add to SSH Agent

    Once generated copy and paste it on your github settings:
    Add SSH key to Github Account

    Clone again the repository with --recursive option

    Best regards, hope this is useful to you!

    I had to add github SSH key from my machine to github to avoid submodules access error

    That could be the problem since all the missing links are related to wifi. How did you add the WIFi key?

    But this lib exists. Here is the list of submodules.
