I have a custom board loosely based off the i.MX53 QSB with a dedicated USB client port and separate dedicated USB host port. I am trying to get USB client functionality working in mainline u-boot 2015.04. I have verified that USB client/gadget functionality works when booted into Linux on the board. In u-boot I have tried testing USB client with USB Mass Storage, DFU, and FastBoot and none of them seem to work.
Here is my USB client #defines from my config header file: #define CONFIG_CI_UDC #define CONFIG_USBD_HS #define CONFIG_USB_GADGET_DUALSPEED #define CONFIG_USB_GADGET #define CONFIG_CMD_USB_MASS_STORAGE #define CONFIG_USB_GADGET_MASS_STORAGE #define CONFIG_USBDOWNLOAD_GADGET #define CONFIG_USB_GADGET_VBUS_DRAW 2 #define CONFIG_USB_ETHER #define CONFIG_USB_ETH_CDC #define CONFIG_G_DNL_VENDOR_NUM 0x0525 #define CONFIG_G_DNL_PRODUCT_NUM 0xa4a5 #define CONFIG_G_DNL_MANUFACTURER "FSL" #define CONFIG_SYS_CACHELINE_SIZE 64
Additionally here are my #defines for the USB host functionality: /* USB Host Configs */ #define CONFIG_CMD_USB #define CONFIG_USB_EHCI #define CONFIG_USB_EHCI_MX5 #define CONFIG_USB_STORAGE #define CONFIG_USB_HOST_ETHER #define CONFIG_USB_ETHER_ASIX #define CONFIG_USB_ETHER_MCS7830 #define CONFIG_USB_ETHER_SMSC95XX #define CONFIG_MXC_USB_PORT 1 #define CONFIG_MXC_USB_PORTSC (PORT_PTS_UTMI | PORT_PTS_PTW) #define CONFIG_MXC_USB_FLAGS 0
Here is my board file content related to USB: #ifdef CONFIG_USB_EHCI_MX5 static void setup_usb(void) { imx_iomux_v3_setup_pad(MX53_PAD_GPIO_0__GPIO1_0); }
int board_ehci_hcd_init(int port) { /* Enable USB_H1_VBUS power with GPIO1_0 */ gpio_direction_output(IMX_GPIO_NR(1, 0), 1); return 0; } #endif
int board_usb_phy_mode(int port) { if (port == 1) return USB_INIT_HOST; else return USB_INIT_DEVICE; }
Then later on in board_init(), I have: #ifdef CONFIG_USB_EHCI_MX5 setup_usb(); #endif
When I run the 'ums 0 mmc 0' command, I get the following: UMS: disk start sector: 0x0, count: 0xe88000 and then I get an infinite spinning progress indicator. At this point when I connect the USB cable to a Host PC, I see nothing on the host PC side (Windows or Liunx).
Any ideas on what I am missing to get USB client working or any hints on how to debug this further.
