Standalone programming

Paul Holmes

OK, I've written my code, compiled it,
programmed it into my board and everything
works.

Now I need to hand over the binary code
to our subcontractor, so he can program up a
few thousand boards, while I get going on the
next piece of code.

I don't want the subcontractor to be able to
change, re-compile, or even see the source
code.

I have a spare ULINK box for the subcontractor,
but what software will he need, and how can
he load the .hex, .elf or whatever into it?

    for programming chips, all you need is the .hex file. If anything else is needed that would be totally ridiculous, so get another programmer if it is so.
    I have worked with BP micro Xeltek, needhems and many more and none have needed more than a .hex file

    Thanks Erik,

    The way the boards are put together, the only
    convenient way to program them is via JTAG.
    (Programming the chips before they are
    soldered onto the board might be possible,
    but it would make me very unpopular with
    our production people.)
    I already have the ideal hardware for JTAG
    programming - or so I thought - namely the ULINK box.

    With other types of tool, e.g. our FPGA
    toolchain, there is a standalone programming
    mode for the software, which takes a .pof
    file and programs it into the config device.
    (It even does standalone programming without
    the dongle so it doesn't tie up a seat if
    you don't need to compile, but that's a
    side issue.)

    By analogy, I thought that maybe UVision 3
    might have a similar mode. The problem is
    that if I give UVision a .hex file, but no
    source code, the flash load button is greyed
    out. This happens regardless of whether the
    IDE is running as eval or fully licensed.

    I can't seem to find any way of programming
    a board through JTAG unless the code was
    compiled on the same machine that is being
    used with ULINK.

    Maybe I will need to get another programmer,
    but before I do, does anyone know how to
    work around this?

    ULINK can be used as Device Programmer for various Flash devices including the on-chip Flash of several 8051, XC16x, and ARM devices. Flash programming is even possible with an Evaluation Version. It is not required to have a full version of the Keil uVision for Flash programming.

    You may use the uVision Batch mode during production.

    Thanks Reinhard,

    I still couldn't get it to work with only a
    .hex file, but by using a .elf file
    I managed to get it to work.

    I hadn't realized that I still had to create
    a local project, even though I wasn't compiling
    there, and then rename the .elf file to match
    the project name.

    Anyway, it works now, so many thanks.

    Paul.
