error:flash download failed - "cortex-m3"

when I try to download code to flasH I get "error:flash download failed - "cortex-m3"". I tried to create my own Flash but couldn't set start and end addresses. How can I set init-end sdresses in Utilities-Settings? Or the problem is because of something else? PLEASE HELP! Thanks.

  • This time I used another flash algorithm with base adress 0x0 and size 256k and got the following:

    Load "STM3210C_EVAL\\STM3210C_EVAL.axf"
    Erase Done.
    Programming Done.
