ByteStreamDriverModel Undefined Build Error With Latest Tutorial

Hi y'all,

I was going through the Hello World: Integration and Testing With F´ Deployments page just to get acquainted with the latest F Prime updates (the updates to prime-util are phenomenal by the way) and I keep getting this issue when trying to build the HelloWorldDeployment:

[ 97%] Generating HelloWorldDeploymentTopologyAppAi.xml, Ports_RateGroupsEnumAi.xml
fpp-to-xml
/workspace/MyProject/HelloWorldDeployment/Top/instances.fpp:108.27
  instance comDriver: Drv.ByteStreamDriverModel base id 0x4000 \

gmake: *** [Makefile:2418: HelloWorldDeployment] Error 2
[ERROR] CMake erred with return code 2

I'm using the latest F Prime version on devel (commit f34d596) and running the following commands:

cd MyProject/HelloWorldDeployment
fprime-util build -j $(nproc)

I also opted for the default responses when creating the component and deployment unless otherwise instructed by the tutorial.

Any thoughts as to what could be going wrong?

Note: fprime-util new is intended to be used with the latest tag of F´. That is why this issue occurred (as devel was updated).

We fixed this issue here: nasa/fprime-tools#167 and that fix will be consistent with F´ at the next release!

Packet XML parsing error: Channel helloWorld.GreetingCount does not exist

I am following the same tutorial and encountered the same issue regarding ByteStreamDriveModel. The update mentioned above fixed that issue however, now I am seeing the XML error stated above.

The tutorial mentions to move helloWorld.GreetingCount to the ignore section in the HelloWorldDeployment/Top/HelloWorldDeploymentPackets.xml. Do I need to make any changes there?

Thanks in advance.

@thvarkey did you make sure to update the HelloWorldDeploymentPackets.xml, as shown here ?

[thvarkey]

@thomas-bc Correct, I updated the ignore section as you mentioned in the link. Question: Do I need to go back to previous section of the tutorial to regenerate any of the files?

@thomas-bc Please find some of the details:

Packet SystemRes2 size 101/111
Packetizing SystemRes3 (7)
Packet SystemRes3 size 85/111
Packet XML parsing error: Channel helloWorld.GreetingCount does not exist

[thomas-bc]

Hmm no you shouldn't need to... but maybe just for the sake of being sure, try

fprime-util purge -f

Then re-generate and build:

fprime-util generate
fprime-util buid

[thvarkey]

@thomas-bc Unfortunately, I am still getting the same error. Please see below the ignored packets section from my HelloWorldDeploymentPackets.xml

<!-- Ignored packets -->

<ignore>
    <channel name="cmdDisp.CommandErrors"/>

    <channel name="helloWorld.GreetingCount"/>
</ignore>

[LeStarch]

Packet XML parsing error: Channel helloWorld.GreetingCount does not exist means the HelloWorld component does not yet define the telemetry channel GreetingCount.

Make sure that step was followed.

[thvarkey]

@LeStarch @thomas-bc That was the error. Thank you so much
