Hi,
I am not measuring 5v on the USB VBUS signal.
Here is my kernel configuration related to USB:
fgrep USB .config | grep -v '^#'
CONFIG_USB_HID=y
CONFIG_USB_SUPPORT=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_DEVICE_CLASS=y
CONFIG_USB_MUSB_HDRC=y
CONFIG_USB_MUSB_SOC=y
CONFIG_USB_MUSB_HOST=y
CONFIG_USB_MUSB_HDRC_HCD=y
CONFIG_USB_TI_CPPI_DMA=y
CONFIG_USB_STORAGE=y
CONFIG_USB_TEST=y
CONFIG_USB_OTG_UTILS=y
CONFIG_NOP_USB_XCEIV=y
The schematic (http://designsomething.org/leopardboard/uploads/dm365_leopard_board_ver1.3.pdf) shows GPIO66 is connected to DRV_VBUS, so I changed the arch/arm/mach-davinci/board-dm365-evm.c file (we are in the process of making a board-dm365-leopard.c file) to have
static void dm365evm_usb_configure(void)
{
gpio_request(66, "usb-vbus");
gpio_direction_output(66, 0);
setup_usb(500, 8);
}
My hardware configuration is:
a) Leopardboard 365 v 1.3
b) LI-DVI1 v 1.3
c) USB mini-B to A converter that came with the DM6446 EVM
d) Logitech track ball that was tested working with a HawkBoard (and I measured 5v on VBUS on HawkBoard to verify I was measuring the right signal)
e) Leopardboard 365 powered with 3a 5v power supply
I am not seeing 5V on USB VBUS.
What configuration step am I missing?
Todd
P.S. here is the boot output (I have a USB serial dongle connected)
