Flashing Intel hex code problem in omapl138

Hi,

I am trying to flash my application into the flash memory of OMAPL138. for that i am using SPI1 and i created Intel hex code from the ccs4. Its size is nearly 1130 bytes, and staring address is 0x60000800. whenever i am trying to flash this code i just found that after successful  writing of 700 bytes it showing error . that is the next 12 bytes of data not writing to the flash (the same 12 bytes are written as FFFFFF). if i try to flash a small sized application its writing without any issue. 

Thank you.
