I've been looking at getting fastboot working on my LG Optimus Black (P970), codename sniper, port. I found out that the BeagleBoard code is using that too, so I copied the required config options:
#define CONFIG_MUSB_GADGET #define CONFIG_USB_MUSB_OMAP2PLUS #define CONFIG_MUSB_PIO_ONLY #define CONFIG_USB_GADGET_DUALSPEED #define CONFIG_TWL4030_USB 1 #define CONFIG_USB_ETHER #define CONFIG_USB_ETHER_RNDIS #define CONFIG_USB_GADGET #define CONFIG_USB_GADGET_VBUS_DRAW 0 #define CONFIG_USBDOWNLOAD_GADGET
#define CONFIG_G_DNL_VENDOR_NUM 0x0451 #define CONFIG_G_DNL_PRODUCT_NUM 0xd022 #define CONFIG_G_DNL_MANUFACTURER "TI" #define CONFIG_CMD_FASTBOOT #define CONFIG_ANDROID_BOOT_IMAGE #define CONFIG_USB_FASTBOOT_BUF_ADDR CONFIG_SYS_LOAD_ADDR #define CONFIG_USB_FASTBOOT_BUF_SIZE 0x07000000
And removed the ones that relate to the legacy code:
-#define CONFIG_MUSB_UDC 1 -#define CONFIG_USB_OMAP3 1 -#define CONFIG_TWL4030_USB 1 -#define CONFIG_USB_DEVICE 1 -#define CONFIG_USB_TTY 1
I also added the relevant "platform" data: http://git.code.paulk.fr/gitweb/?p=u-boot-sniper.git;a=blob;f=board/lge/snip...
The current state of the port is available for reference at: http://git.code.paulk.fr/gitweb/?p=u-boot-sniper.git;a=shortlog;h=refs/heads... It is not yet ready to be pushed upstream.
With all this, I run the fastboot command and UART shows: musb-hdrc: peripheral reset irq lost!
On the host side, I get the following messages from dmesg:
[11281.565099] usb 3-1: new high-speed USB device number 39 using xhci_hcd [11283.178280] usb 3-1: Device not responding to set address. [11283.378663] usb 3-1: Device not responding to set address. [11283.579739] usb 3-1: device not accepting address 39, error -71 [11283.939123] usb 3-1: new high-speed USB device number 41 using xhci_hcd [11283.939313] usb 3-1: Device not responding to set address. [11284.140316] usb 3-1: Device not responding to set address. [11284.341381] usb 3-1: device not accepting address 41, error -71
and so on until it fails: [11286.007890] hub 3-0:1.0: unable to enumerate USB device on port 1
So it fails early. Is there something more I need to do in order to get the new musb driver to work properly on my device?
