JS110 Firmware update

Issues
1

Hello, I’m trying to update my JS110 firmware.
This is what the Python commands return:

PS C:\Users\romai\Desktop\pyjoulescope> set JOULESCOPE_BACKEND=0
PS C:\Users\romai\Desktop\pyjoulescope> python -m joulescope info
System information
    Python: 3.11.4 (tags/v3.11.4:d2340ef, Jun  7 2023, 05:45:37) [MSC v.1934 64 bit (AMD64)]
    Platform: Windows-10-10.0.22631-SP0 (win32)
    Processor: AMD64 Family 25 Model 33 Stepping 2, AuthenticAMD
    executable: c:\Users\romai\Desktop\pyjoulescope\.venv\Scripts\python.exe
    frozen: False

joulescope version: 1.1.15
Found 1 connected Joulescope:
    JS110-001428   ctl=                 sensor=

And running the update ends with a bootloader error:

PS C:\Users\romai\Desktop\pyjoulescope> python -m joulescope program upgrade "js110_1_3_4.img"

         ^^^^^^^^^^^^^^^^^^^^^^^

    b, _ = device.bootloader(progress_cbk=cbk)
           ^^^^^^^^^^^^^^^^^
AttributeError: 'DeviceJs110' object has no attribute 'bootloader'

Maybe there is something wrong with my Python installation, or the actual JS110 firmware is too old?

The commands you ran were for the older Windows Command Prompt. However, it looks like you are using PowerShell. Here are the equivalent commands for PowerShell:

PowerShell 7.4.5
PS C:\> $env:JOULESCOPE_BACKEND = "0"
PS C:\> python -m joulescope info

    Processor: Intel64 Family 6 Model 183 Stepping 1, GenuineIntel

Does this work for you?

Dumb me :man_facepalming: I was using the Terminal within VS Code.

The command does work and the update was successful!
