Hello, 

As you might know,  there are some of the documents and libraries which are under NDA (Non-Disclosure Agreement) and placed in DocStore, could you please follow this guides? 

Docstore tutorial part 1: User Registration|NXP 

Docstore tutorial part 2: portal usage|NXP 

Also, you will need to contact one of our distributors available in the  Distributor Network|NXP to help you through the NDA process. 

Regards, 

Estephania
