Write data into NOR Flash sector

Hi all,

   I am working on BF609, When i try to write some data like 0x1254 in particular sectors using pc28f128P33_Write() into nor flash. It writes the data into that sector.

But when I read that sector it cannot give the exact data I passed into that sector, the write and read addresses are same. Before write when I read it gives some data value and after write it gives the value which is not matching, every time the same values shown even when I write into another sectors.

Please somebody help me to fix this issue.

  • Hi,

    After erasing all sectors, we are able to write and read the values correctly. please refer the screenshot.
    To assist you better,can you please share us the below points.
    1. Are you using custom board or Ezkit.
    2. Can you please try to flash simple led program in to the parallel flash and let us know the result. Device programmer "bf609_pc28f128p33_dpia.dxe" is used to communicate with flash and load the ldr in the flash.
