Part Number:AM5718
Hi everybody ,
Our board has an AM5718 processor with one USB host and one USB device (see attached image), we need to implement USB 2.0 "test packet" compliance test for the host. To accomplish this task a fixture has been plugged with an oscilloscope at its other end so to measure the "eye diagram".
We followed the procedure showed in
http://processors.wiki.ti.com/index.php/Linux_Core_DWC3_User's_Guide
with no apparent error,
"/sys/kernel/debug/48890000.usb/testmode" value is "test_packet" as commanded but nothing appears on the oscilloscope.
DCW3 seems not to respond to the sent command, our kernel is 4.9.45-rt23, is there any possible reason why the test is not working ?
