您好,AM335X u***0设置host模式,软件部分是不是只是在这个地方修改就行了,我的内核版本3.2 static struct omap_mu***_board_data mu***_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, ]; |

USB0做HOST有问题么? USB做主,硬件要按照下面的参考: http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist#USB |
