Other Parts Discussed in Thread: DM3730, DA8XX
Having some trouble getting USB working, and I hope someone can help out.
We're running the SMSC3320 ULPI transceiver on HSUSB1 (DM3730, custom board based on EVM reference design). I have EHCI support enabled in the kernel and the port settings in place (see below). During the kernel boot, everything appears to start up correctly, and the device is found. All the signals coming out the transceiver appear valid. However, when, I plug in a USB device, it is unable to communicate with the device, giving the error "usb 1-1: device descriptor read/64, error -71" (Protocol Error). This occurs with both self-powered hubs and USB flash drives.
I also notice that during the boot process, the soft phy reset is timing out. I tried communication with a few other ULPI PHY-side registers, and they are all timing out. That may be a contributing factor, or just a red herring.
Board Config:
static struct ehci_hcd_omap_platform_data ehci_pdata __initdata = {
.port_mode[0] = EHCI_HCD_OMAP_MODE_PHY,
.port_mode[1] = EHCI_HCD_OMAP_MODE_UNKNOWN,
.port_mode[2] = EHCI_HCD_OMAP_MODE_UNKNOWN,
.phy_reset = true,
/* PHY reset GPIO will be runtime programmed based on EVM version */
.reset_gpio_port[0] = 25,
.reset_gpio_port[1] = -EINVAL,
.reset_gpio_port[2] = -EINVAL
};
