    This does not actually seem to be a BIOS or NDK  issue, so I am going to move it to the DM64x forum to hopefully get it a faster response.

    There is an example in TI dvsdk itself. The demo provided in the dvsdk includes the source code and a small application to program it in flash memory with source code. See instructions under:

     

    "C:\dvsdk_x_xx_xx_xx_DM648\flashutil\DM648 EVM Flashing and Booting Instructions.doc"

     

    Replace C:\dvsdk_x_xx_xx_xx_DM648 with TI dvsdk installation path.

    I already had done work on this code you mentioned several times but this allows you only to burn the complete nor flash with UBL.ais and UserProject.ais however i just want to write few bytes in NOR flash at some specific locations i just need that.

    Here is the response from Lyrtech Inc:

    [Lyrtech] Programming a whole file or only few bytes can be done with the same routines. Just don't forget that you will have to erase a complete flash sector before programming your few bytes (so it would not erase one byte at a time, but a bunch of them)
