New firmware release v1.14.0.b1 (Dual core support and CAN bus)

[daniel]

Hello,

We have just released firmware v1.14.0.b1. These are the release notes:

• esp32: Make sure that static mutexes are allocated from internal memory only and never from pSRAM.
• esp32: Fix bug with LoRaWAN downlinks on the LoPy4.
• esp32: Add CAN bus class. Heavily based on to Thomas Barth's implementation: https://github.com/ThomasBarth/ESP32-CAN-Driver. See docs here: https://docs.pycom.io/chapter/firmwareapi/pycom/machine/CAN.html
• esp32: Enable dual core support. WiFi, BLE and TCP/IP run on core 0. MicroPython, LoRa and Sigfox run on core 1.
• esp32: Update application to the latest IDF. Fixes several I2C problems.
• esp32: Add queue module. Based on: https://docs.python.org/3/library/queue.html
• esp32: Correct LoPy4 flashing scripts and fix os.uname() crash.

Cheers,
Daniel

@robert-hh
Yes, i have seen it before. Great work :)
But it require to store somewhere font in particular size.
This is simple alternative.

[robert-hh]

@livius That's nice. You may however also have a look at the work of Peter https://github.com/peterhinch/micropython-font-to-py
It deals a lot with fonts, and it is well suited to large & nice fonts and use it with the framebuffer module.

[livius]

if someone is interested i have added simple font size scaling to framebuf
https://github.com/pycom/pycom-micropython-sigfox/pull/131
result on small oled

[livius]

When framebuf will be updated to support all formats?
now it cover MVLSB, RGB565, GS4_HMSB
but official micropython cover MVLSB, RGB565, GS2_HMSB, GS4_HMSB, GS8, MHLSB, MHMSB

Any plans to update documentation on using the CLI version of the updater tool?

I will provide documentation for the CLI tool with the next release as I'm currently re-designing the command line parameters.

If you want to flash your board after building it from source please use make flash instead.

release v1.14.0.b1 is crashing during boot process on one of my LoPy4 (no software loaded). At least two other LoPy4 are working with new release v1.14.0.b2.
With v1.9.2.b2 (original hardware on delivery) the failed LoPy4 is working.

@colateral said in New firmware release v1.14.0.b1 (Dual core support and CAN bus):

self.serial = serial.Serial(port, baudrate=115200, bytesize=serial.FIVEBITS, timeout=0.25)

Can you please try to replace above line in tools/pypic.py with:

self.serial = serial.Serial(port, baudrate=115200, bytesize=serial.FIVEBITS, timeout=0.25 exclusive=True)

P.S. I made a small edit after I posted this originally.

For lopower consideration, to run only on one core, what we have to configure in the build ?

[brotherdust]

Any plans to update documentation on using the CLI version of the updater tool? Maybe I'm just using it wrong:

.\pycom-fwtool-cli.exe -f "C:\Users\xxxx\Code\Pycom\pycom-microp
ython-sigfox\esp32\build\LOPY_915\release\appimg.bin" -p COM3 --pypic flash
Connecting.....

Changing baud rate to 115200
Changed.
Exception: Timed out waiting for packet content, on line 204

Thanks!

Updated a LoPy (1.0) that was running a simple rainbow animation of a set of 8 WS2812b neopixels. On previous versions, the animation tended to be choppy at times. After upgrading to v1.14.0.b1 with dual processor support, the animation is SMOOTH! Nice!

@rskoniec
We sent customised APN LTE firmware to partners (inc Hologram) but testing didn't went as well as we hoped, we're working on it

Thank you.

[crumble]

@daniel does this mean, that we cannot use multi core from user level or do we only have to wait until it is documented?

[livius]

@robert-hh
Yes, this is really awaited improvement.
If i look ok into sources it is pinned to 1

@daniel said in New firmware release v1.14.0.b1 (Dual core support and CAN bus):

esp32: Enable dual core support. WiFi, BLE and TCP/IP run on core 0. MicroPython, LoRa and Sigfox run on core 1.

Hi Daniel, this is a great improvement. Is the LTE support running on Core 0 as well?

Just a few notes in case you missed the previous release...

We recently released a new firmware update tool 1.1.6.b0. With this version the installer for Windows and MacOS will consist of only two executables, one which provides the GUI version called pycom-fwtool and another CLI version called pycom-fwtool-cli which replaces the functionality of the previous bin/updater.py file

It is highly recommended that MacOS users remove the old application completely before installing this new version (or re-installing it if you have it already installed it). This will make sure all the old frameworks are removed which should save a considerable amount of disk space.

During internal testing I discovered a bug where, when you try to update/register more than one Sigfox device for the first time using the restart button, the download seems to take forever when updating the second device. I will upload a bugfix for this as soon as possible.

A bugfix for this is now available as a beta release for [LINK NO LONGER AVAILABLE]. I will upload this new version as a general release later today.

What about Set Cellular Access Point Name (APN) ?
