TMS320C6748: Read and write between DSP and NAND flash

Hello, 

We want to write the data from the DSP to the NAND FLASH and store it, and then read it after all the storage is complete.

But when DSP writes data into 16-bit NAND Flash through the EMIFA interface, and then reads it again. The number read is messy. What is the reason? The CS3 chip select of the EMIFA interface of DSP is connected to NAND FLASH. The main program is shown in the figure below:

The numbers on the write bus and the read bus are inconsistent. I found that the read address is different from the write address. How to solve this problem?

How to store the data in NAND FLASH, and then read it out correctly, I really need help, and I hope to receive your reply as soon as possible. Thank you very much!
