      yeah that's working fine .

      but i dont want that ,i converted sof file to .flash file and write it in ox20000 onwards by receiving the data in .flash file through uart but it is not booting on power on .

      do we need to write other than converted sof file to boot up on power on .

      do i need to convert pof file to hex file and write that data from 0x20000 onwards but pof file is having other data than .sof file do we need convert pof file and write to flash i want to know that data .

      or any other suggestions . actually in all pdfs its mentioned we have to write from 0x20000 onwards
