Hi,
Our custom board use 2 Host port , so i modify the source code :
static struct omap_musb_board_data musb_board_data = {
.interface_type = MUSB_INTERFACE_ULPI,
/*
* mode[0:3] = USB0PORT's mode
* mode[4:7] = USB1PORT's mode
* AM335X beta EVM has USB0 in OTG mode and USB1 in host mode.
*/
.mode = (MUSB_HOST << 4) | MUSB_HOST,
.power = 500,
.instances = 1,
But when our usb device connect , no any response on kernel.
Any suggest ? Thanks.
This is kernel message when boot :
