最近发现TI样片无法申请了，点击样片申请选项，直接弹出：
Your company or university does not have access to order free samples from Texas Instruments. If you have reached this page, you have been declined access to place sample orders. If you believe you have reached this page in error, please check that you have logged into your myTI account with your corporate or university email address.
If you would like to purchase devices, please go to the TI store. We offer expedited shipping and multiple payment options to get your order placed quickly and into your hands.
请问这是怎么回事呢？请问 怎么开通这个权限呢？之前是可以申请的。
