4.3.1
Utilities
The definition of a MOTLoad utility application is very broad. Simply stated, it is considered a 
MOTLoad command if it is not a MOTLoad test. Typically, MOTLoad utility applications are 
applications that aid the user in some way (that is, they do something useful). From the 
perspective of MOTLoad, examples of utility applications are: configuration, data/status 
displays, data manipulation, help routines, data/status monitors, etc.
Operationally, MOTLoad utility applications differ from MOTLoad test applications in several 
ways:
z
Only one utility application operates at any given time (that is, multiple utility applications 
cannot be executing concurrently).
z
Utility applications may interact with the user. Most test applications do not.
4.3.2
Tests
A MOTLoad test application determines whether or not the hardware meets a given standard. 
Test applications are validation tests. Validation is conformance to a specification. Most 
MOTLoad tests are designed to directly validate the functionality of a specific SBC subsystem 
or component. These tests validate the operation of such SBC modules as: dynamic memory, 
external cache, NVRAM, real time clock, etc.
All MOTLoad tests are designed to validate functionality with minimum user interaction. Once 
launched, most MOTLoad tests operate automatically without any user interaction. There are a 
few tests where the functionality being validated requires user interaction (that is, switch tests, 
interactive plug-in hardware modules, etc.). Most MOTLoad test results (error-data/status-data) 
are logged, not printed. All MOTLoad tests/commands have complete and separate 
descriptions (refer to the MOTLoad Firmware Package User’s Manual for this information).
All devices that are available to MOTLoad for validation/verification testing are represented by 
a unique device path string. Most MOTLoad tests require the operator to specify a test device 
at the MOTLoad command line when invoking the test.
A listing of all device path strings can be displayed through the devShow command. If an SBC 
device does not have a device path string, it is not supported by MOTLoad and can not be 
directly tested. There are a few exceptions to the device path string requirement, like testing 
RAM, which is not considered a true device and can be directly tested without a device path 
string. Refer to the devShow command description page in the MOTLoad Firmware Package 
User’s Manual
.
Most MOTLoad tests can be organized to execute as a group of related tests (a testSuite) 
through the use of the testSuite command. The expert operator can customize their testing 
by defining and creating a custom testSuite(s). The list of built-in and user-defined MOTLoad 
testSuites, and their test contents, can be obtained by entering testSuite -d at the 
MOTLoad prompt. All testSuites that are included as part of a product specific MOTLoad 
firmware package are product specific. For more information, refer to the testSuite 
command description page in the MOTLoad Firmware Package User’s Manual.
