Introduction ------------- This text document accompanies the MUSB CCS test case for DM814X EVM. It provides a brief of the methodology of the test and the procedure for executing the same. Overview --------- This CCS test application validates the MUSB for its ability to perform device connect/disconnect. It also validates the speed and VBUS level post device connect. board setting: ------------- PINS 1 and 2 of jumper J23 must be shorted on baseboard. Procudure ---------- This test application assumes the MUSB controller initialization as well as all the PLL initialization already carried out by the GEL scripts. At the minimum the following GEL scripts are to be executed. 1. PG 2.x DM814X --> ALL_ADPLL_CLOCKS_ENABLE_API 2. PG 2.x DM814X --> USB_CLOCK_ENABLE load "BB_018_USB1_HOST_Test.out" file and run. The test is declared a PASS if the device is connected/disconnected gets displayed in the console and the device speed/VBUS levels are detected correctly.
