problem with routes in Code Modules

PHP Code:

// namespace acp/Blog

$psr4 = [
    'App'         => APPPATH,                     // To ensure filters, etc still found,
    APP_NAMESPACE => APPPATH,                     // For custom namespace
    'Config'      => APPPATH . 'Config',          // Config namespace
    'acp\Blog'    => ROOTPATH.'acp\Blog',         // Acp Blog module
]; 


What did you Try? What did you Get? What did you Expect?
