Hi Jason,
Please execute the following code in MATLAB command line and then try to build the model:
sppkgroot = codertarget.arduinobase.internal.getSpPkgRootDir;
srcFolder = fullfile(sppkgroot,'arduinoutilities');
srcFile = fullfile(sppkgroot,'arduinoutilities','arduinoCANMsg.m');
parentFolder = fullfile(matlabroot, 'toolbox', 'target');
destFolder = fullfile(matlabroot, 'toolbox', 'target', 'arduinoutilities');
destFile = fullfile(destFolder, 'arduinoCANMsg.m');
if ~exist(destFolder,'dir')
[success, ~, ~] = mkdir(parentFolder, 'arduinoutilities');
if ~success
error(message('arduino:build:CANMsgFolderCopyError',sppkgroot,parentFolder));
end
end
if ~exist(destFile,'file')
[success,~,~] = copyfile(srcFile, destFolder, 'f');
if ~success
error(message('arduino:build:CANMsgFileCopyError',srcFolder, destFolder));
end
addpath(destFolder);
else
addpath(destFolder);
end
This should solve the problem.
In case of any error, please run MATLAB as administrator and try again.
If you still run into any issues, please contact Mathworks Technical Support.
Hope this helps!
