how to run stand alone?

Other Parts Discussed in Thread: UNIFLASH, CC3200

I am trying to get my application to run stand alone (without the debugger / pc). I thought it was as simple as flashing the output file.bin with uniflash... but this does not work.... so what steps to take to get it to work without my pc attached?

    Hi,

    Some operations are possible only via Uniflash such as format.

    However, most operations can be applied also via your host. You can update service pack (although it is much more convenient via Uniflash) and program any file you want, including mcuimg.bin. You need to note that each file you would like to program needs to reside on your host, probably as a C-array (you need to provide it to file system APIs). Special care for mcuimg is required since CC3200 executes mcuimg stored on serial flash by loading it to RAM and execute. So you can replace the mcuimg binary on serial flash but if the application is erroneous you can get stuck

    Thanks, but how do I get my output.bin file to run after I downloaded it to the board with uniflash?

    I named it /sys/mcuimg.bin in uniflash.
    press 'programm'
    all okay
    but then nothing happens....

    I expected the same behaviour as when running it from css....

    Hi,

    Can you share the Uniflash Console screen during flashing?

    Also, please note the followings:

    1. during flashing, SOP2 jumper should be connected but should be disconnected if you want the application to run. Have you done it?
    2. not sure if you formatted the flash using Uniflash. Can you elaborate what procedure you took with Uniflash?
