      Hi Raju,

      Can i use Remaining Space for Data Flash? 
      >> Yes, you can use the remaining space for DATA. By default, Boot process starts from the 0x00000000 address of the memory device and it occupies the space required for application. So to avoid overwrite between LDR application and DATA stored, Its a good practice to store DATA in the Last sectors of the memory device.
      Also, Please note that while booting dont use -cmd erase , it will erase all sectors in device memory. Instead use -cmd eraseaffected which erases the specific sector in device memory. 

      Can I Write Data In to Flash Through Application Code.
      >> Use the attached Flash write code to write the data in a particular sector.
      Please note that you have to change the configuration as per your Flash part.BF60x_Flash_Test_Core0 .C.zip
