Hello Nana,
It is hard to say where the problem might be without seeing what is going on the bus. Do you have a logic analyzer or an oscilloscope to see your read access? Can you please share with us your source code?
It might be better to create a standard ticket for a private discussion by following these steps:
1) Please open www.nxp.com
2) On the top level menu, select Support > Sales and Support (http://www.nxp.com/support/sales-and-support:SUPPORTHOME).
3) On the bottom of the page, select Hardware & Software.
4) Register with your business email to access the technical NXP online support.
5) A verification email will be sent to your account. Click the embedded link to verify your access.
6) On the NXP online support page, select Contact Support from the top menu and click “submit a new case” to start the process.
Regards,
Tomas
