Hi Guoqiang,
By AN4704SW you mean MTRCKTSBNZVM128?

This software works correctly on my side.
Please check whether you have correctly configured jumper setting per quick start guide:
http://www.nxp.com/docs/en/user-guide/MTRCKTSBNZVM128QSG.pdf
Do you use the default LINIX motor from MTRCKTSBNZVM128 kit?
Did you make any modifications in the code or configuration?
When code runs in special mode and not in normal mode, the most typical reason is incorrect writing into registers with write once condition like CPMUCOP or MODRRx registers.
I hope it helps you.
Have a great day,
Radek
