    I am using IAR 430A Kickstart to debug my str710 board.

    I want to download the example program to ext sram 0x62000000.

    But when I download the program, It can go to main as flow:

    --- Now branches to a C lib function

    b ?main ; Note : use B not BL, because an application will

    ; never return this way

    But when I step to go.It can't go to my main function.

    I don't know why

    Yes,I have initialize EMI using the same macro.

    But when I download the program to 0x20000000,It works well.

    When I download the program to 0x62000000, It can't go to main

    function.

    No,I don't know why.

    My project is just the ST Lib example. I link it to 0x20000000

    It works well. But I link it to ext sram 0x62000000,It can't go to main.

    How can I download my program to EXT.SRAM?

    My board has a ISSI SRAM IS61LV25616-10T using CS1 pin.

    But I can't download my program to 0x62000000.

    I am using ADS.

    Hi Zouh,

    I am sorry.It can't work.

    Maybe my board is something wrong.
