Succesive writes and reads in the Qspi flash memory

Hello. I'm trying to execute the example "xqspips_flash_lqspi_example.c". It works fine if you execute the example one time but I need to write and read many times in the same address region of the Qspi. When I try to write and read more than one time in the test_address region of the example I am not able to write and read new data. I get the previous data in the ReadBuffer. However, if I Try to write to a different region, I am able to do it and I get the new data  in the ReadBuffer that I pretend to write.

 

Thanks in advance.
