CCS/AM3352: Problem under WinCE

Part Number: AM3352


Tool/software: Code Composer Studio

hi  Team:

1. When I use  linux system and wince system ,  DDR2  is  normal

2. when I use  wince system ,  DDR3  is  unnormal,the DDR3 Memory reduced  by 4k in about a second (Linux normal) ,open my device, control panel, system properties, memory, and find that the memory in use has been reduced; why? how to  solve?

3. Usb for wince system, unplug sometimes undetected; WINCE7\public\ oak\drivers\usb\ HCD \usb20\usb2com\cdevice. CPP GetDescriptorD reads dwBytesTransferred's value and wDescriptorSize are not equal, and dwErrorFlags flag is error state, so usb initialization was not successful.  why?
