Why is the dropdown menu for the "Servox_Function" in QGC not displaying correctly

[s5377689 (L)]

Sorry to bother, but could someone guide me on this?
I added k_waterwing = 157, in SRV_Channel.h and added the following in SRV_Channel.cpp:
// @Values: 157:Waterwing
// @Values{Rover}: 157:Waterwing
Then I executed the following commands under ardupilot:

./waf clean
./waf configure --board sitl
./waf rover
cd Rover
…/Tools/autotest/sim_vehicle.py -v Rover -f motorboat-skid --console --map

I opened QGC and checked Parameters → servox_function.
First Question: Why doesn’t the dropdown menu show Waterwing?
Second Question: When I use Advanced settings → Manual Entry to select 157, why does it display Unknown: 157 instead of Waterwing?

I’m not an expert at this but since no one else has replied I will give it a shot.

I think the ground control software gets the parameter descriptions from the standard code base, so your new parameters won’t show up unless you have a successful pull request and merge into the main code, or if you modify the files QGC is using. I don’t use QGC much so am not sure about how it goes about it but here are some similar topics related to mission planner that I bookmarked when trying to figure it out in the past. Let us know if you figure it out!

Forcing Mission Planner to load custom parameter definitions?

I’ve generated a set of ParameterMetaData for a custom branch with a whole load of parameters, that I’d like to display in the units/descriptions columns within the Mission Planner full parameter list. I’ve verified that my new parameters are indeed in the ParameterMetaData.xml file, which has been copied to Documents/Mission Planner/, as well as C:\ProgramData\Mission Planner, which are shown as the two data directories in the Mission planner console when it fires up. These parameters appear i…

I believe these are out of date but there is still useful info:

[SOLVED] Description of new parameters not showing

Thanks I didn’t try to go too deep in MP code, but it gives me the keyword to find my solution. In order to add the description/value and so on, I modified two files: D:\Documents\Mission Planner\ParameterMetaData.xml C:\Program Files (x86)\Mission Planner\ParameterMetaDataBackup.xml (loaded only if the first one does not exist)

Adding custom mode to Mission Planner

Thanks for the response, I’ve located the “ParameterMetaDataBackup.XML” this is the one I modified in the thread above. There is no “ParameterMetaData.XML” file. Reading past posts MP uses the backup file if the other doesn’t exist. I’m not clear on why I’m deleting the XML files and what a gzip is. Thanks for the input.
