Can't build for CC3220 with latest mos, mongoose-os, and mos-libs

I've been busy with other projects for a while. Today I thought I'd try to build my mongoose-os project again (for the CC3220SF).

I have pulled the latest mongoose-os repo and also the mos-libs.
I think I have the latest version of the mos utility. Here's the answer I get when issuing the command mos help
The Mongoose OS command line tool, v. 2.4.2+???~brew.
I use the same command line when trying to build my project (that has not been changed).
mos build --platform cc3220 --local --libs-dir ./mos-libs --repo ../mongoose-os --clean --verbose

Now I get the following error message:
Error: can't build for the platform cc3220; only those platforms are supported: [cc3200 esp32 esp8266]

    Can you try issue the command "mos update latest".

    I am trying to build the 'demo-c' example apps
    when I update the mos utility with "mos update release" - the build end up in errors
    but after updating with "mos update latest" - the build is OK.

    I'm using mos on macOS and installed it via homebrew. Don't know if it is possible to do a mos update latest without getting into some other problems.

  • @ulso , I think just make sure the mos executable is in your path, which homebrew should have taken cared of for you and ran it.

    I'm happy to report that it now works fine to build for CC3220 again. Thanks to @rojer

    Hi I'm having the same problem now with the latest MOS tool on windows.
    The Mongoose OS command line tool 201901011519
    When I build i get this error at the end

    Error: /go/src/ can't build for the platform cc3220; only those platforms are supported: [esp32 esp8266]
            /go/src/ build failed
            Error: /go/src/ build failed

    The build works fine when I build with ESP32 without changing anything in the mos.yml file

    Anyone here can help?

    only those platforms are supported: [esp32 esp8266] tells you that one of the libraries is not available for cc3220.

    It works now for the same libraries. Perhaps it was just a bug. However I'm now getting the below error in the mos console after I flash to my CC3220SF-LAUNCHXL
    MJS error: Failed to read file 'app.js

    and I am unable to read values from a DHT sensor, using the js API.

    The libraries in my mos.yml files are as follows:

      - origin:
      - origin:
      - origin:
      - origin:
      - origin:
      - origin:
      - origin:
      - origin: 
      - origin: 
      - origin:
      - origin:
      - origin:

    Have been using a ESP32 and everything was working fine. Am I missing something in relation to the CC3220?

    The support for app.js has been recently added
    You can ignore that error.

    I can't help further because I don't have a CC3220 to test.

    What do you mean by "I am unable to read values from a DHT sensor"? What is the console log saying?
    There is an example-dht-js which should work.

    Hi thanks @nliviu. I am now able to read the DHT values from pin16 of the CC3220, but am unable to read from different GPIO pins.
    I have enabled all of them as inputs with
    GPIO.set_mode(pin, GPIO.MODE_INPUT)

    The pin outs for the C3220 are as shown in the image
    ( "")

    Is there a difference with the GPIO pins?
