Since there is no feedback at current usb audio framework, it may have pop noise/no sound after play some minutes. +How to test auto remote wakeup with the g_zero gadget +1. Prepare a USB host which featured with remote wakeup alternatively, You can +use another i.mx board (like mx50 rdp, or mx6q) for test device board. +2. Boot up both boards, and connect two boards with USB cable. +3. At device side, do below commands: +modprobe g_zero autoresume=3000 interval=1 endms=5000 +we can use the above three parameters to control device send resume signal time. +Autoresume is the minimum number of milliseconds before sending resume signal, +and the time before sending resume signal will automatically increase according +to interval value,the endms is the max number of milliseconds before sending +resume signal.When autoresume is 0 or not be set,the test device auto remote +wakeup function will be disabled. +4. At host side, first do below command: +echo enabled > /sys/devices/platform/fsl-ehci.1/power/wakeup +echo enabled > /sys/bus/usb/devices/1-1/power/wakeup +And you need build a test script to repeat standby the system like below: +while [ 1 ] ;do echo mem > /sys/power/state;sleep 5 ;done +Then run the test script. +5. Then USB device will enter the suspended state ,and autoresume +milliseconds later,the device will send resume signal to wake up host. +6. The expected behavior is: the host device be waked up, and there is not +re-enumeration happens. +7. The host will enter suspended state again,and test case will repeat step +5 and step 6. |
