The problem is seen for all sectors and 1. sector is used as example.

After 1. sector is prepared and erased with SUCCESS return, 0xFF is seen on all sector. It is OK.

Hovewer, after prepare, write and verify command with flash start address as the beginning of this sector and these commands return SUCCESS, first 256 bytes if this sector are filled with 0x00 and RAM source buffer is written after this 256 bytes block.

The test is done on both LPC1768 and LPC1758.

What is the problem? Why does the write and verify command not start with the given address?
