AM335x USB 2.0 COMPLIACE TEST PATTERN GENERATION

F/E

Hi All,

I have to generate the standard test pattern on the USB Host interface in order to analyze the output waveform with an oscilloscope.

Is there any library or driver for the AM335x to generate the USB test pattern for USB 2.0 port in Host mode?

P.S.: OS is LINUX

If you use the 3.2 kernel in AMSDK for AM335x, the following command will generate the test packets on the host port:

echo 'T' > /proc/driver/musb_hdrc.1

echo 'T' > /proc/driver/musb_hdrc.0

depending which controller is used.

This procedure changes in Processor SDK. Recording here for posterity:
