hello, 

i am sorry, my english is poor. 

i read the data from epcs in nios program, and compared it with the *.flash in my PC. i found the first row "S01200006D617869756D696E672E666C617368E2" was not in the epcs,because the first row read from epcs by me was the second row of the *.flash. i want to know where is the first row in the *flash, when i download it to epcs. and what's the significance of the first row in the file of *.flash. 

thanks!

The flash file is in the format of Motorla S-Record. 

 

That first row, "S0..." is the block header information.  

 

Look here for more detail of the S-Record format and you can easily distinguish each line in the flash file.
