Expected result
|
|
===============
|
|
|
|
A second USB serial console (ttyACMx) appears when plugging the USB peripheral
|
|
into a host computer. When opening the serial device it should show the RIOT
|
|
shell. Basic command interaction must work.
|
|
|
|
The test should work on Linux, MacOS and Windows. Putty is known to work on
|
|
Windows.
|
|
|
|
Changing the baud rate, bit mode and parity mode is accepted by the device and
|
|
reflected back. However, changing these should not affect shell operation.
|
|
|
|
Note that when testing with this firmware, the regular USB serial console from
|
|
the attached debugger is not functional.

Background

|
==========
|
|
|
|
This test application can be used to verify the USBUS CDC ACM implementation.
|
|
Assuming drivers available, the board under test should show up on the host
|
|
computer as an USB CDC Abstract Control Management device (ttyACMx on Linux).
|
|
Drivers are available for Linux, macOS and Windows.
