UART - Serial Input/Output Tests
These sections describe the individual UART tests.
Entering UART without parameters causes all UART tests to run in the
order shown in the table below, except as noted.
To run an individual test, add that test name to the UART command.
The individual tests are described in alphabetical order on the following
pages.
You can use the CF command to select the ports to be tested. This example
uses the CF command to select port 0, skipping 1.
Example:
PPCx-Diag>CF UART
External-Loopback Port Mask =00000002? 01
(Bit 0 selects port 0, Bit 1 selects port 1, etc. -- see note below.)
The next parameter is the port selection mask. This mask is used during
testing to identify which ports are to be tested. The default is to test every
port except the console port. The External-Loopback Port Mask is used for
the LPBKE test suite.
