請問...SDK6.0
我看BBB,General EVM 都有usb0_init /usb1_init 來做pinmux init
為什麼AM335X SK 不需要呢????
这个应该是和板子有关系，USB的初始化只是把VBUSDRV设为本来功能，BB和GPEVM应该还把这个脚连成GPIO了，所以要做下初始化。但是SKEVM的板子这个脚应该是只给USB用了
不懂您的意思
BBB 是在哪把這腳位設定為GPIO呢? UBOOT嗎??
static void usb0_init(int evm_id, int profile){ setup_pin_mux(usb0_pin_mux); return;}
/* pinmux for usb0 drvvbus */static struct pinmux_config usb0_pin_mux[] = { {"usb0_drvvbus.usb0_drvvbus", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT}, {NULL, 0},};
