Wu,

Not sure what would cause this problem
Do you see the same error when you run the USB host example from here C:\ti\pdk_am335x_1_0_9\packages\MyExampleProjects\USB_HostMsc_evmAM335x_armExampleProject
Assuming you already have the Processor SDK RTOS package for AM335x from here software-dl.ti.com/.../index_FDS.html
