Other Parts Discussed in Thread: AM3505

I want to try the USB-IF compliance test for our custom board using AM3505 and Linux.

Following LinuxPSP is used.

Following driver is used for USB0(OTG).

/linux-04.02.00.07/drivers/usb/musb/am35x.c

Following driver is used for HSUSB0.

/linux-04.02.00.07/drivers/usb/host/ehci-omap.c

Is the USB-IF compliance test supported by these drivers?

If it is not supported, what should I do to try the USB-IF compliance test?

Best regards,

Daisuke

For the USB-IF compliance test the test objects must output test pattern from its USB port.

Our custom board using AM3505 and Linux is a test object.

Can our custom board output test pattern?

I saw "AM35x-OMAP35x-PSP 04.02.00.07 User Guide" which is document for LinuxPSP.

- "USB EHCI Electrical testing" is supported.

I saw the following link.

- PSP linux driver supports the test modes for OTG port.

I guess the USB-IF compliance test is supported by LinuxPSP.
Is my guess correct?

Best regards,

Daisuke
