Question about Relative Path Variable definitions

Hi,

Where do I find path variable definitions? Such as TARGET_ROOT shown below:

I want to use a different relative path for a different .ccxml config file.

Best,

Hi Kevin,

I can figure out that you need to set a relative path to the project root for a hardware configuration file.

To address this issue, setting the model's InitFcn callback to execute a configuration script is recommended. Below is an initial version of the code to consider. Modifications may be necessary to ensure it aligns with the project's specific requirements.

cs = getActiveConfigSet(gcs); 
% retrieves the active configuration set of the current Simulink model.
ctd = get_param(cs, 'CoderTargetData'); 
% This line extracts the CoderTargetData property from the active configuration set. 
ctd.Runtime.LoadCommandArg = [pwd, '\my_file.ccxml']; 
% The .Runtime.LoadCommandArg property of ctd (CoderTargetData) is then set to this full path.
set_param(cs, 'CoderTargetData', ctd); 
% Finally, the modified CoderTargetData object (ctd), now containing the updated path to the configuration file, is written back to the active configuration set of the model.

I hope that was helpful.

Hi Saurabh,

Thanks for your reply. Yes, you understand what I am wanting to do using a .ccxml config file located in the project root instead.

I'll give your suggestions a try and report back.

Best,

Kevin
