    Hi,

    Can you please tell me what version of the LogicLoader you are using. You may very well need to use the "update" command.

    Thanks,

    I am following these instructions with the images named below:

    OCD Commander instructions to reinstall the bootloader to flash:


    1. Open OCD Commander and connect to your board via the
    CONNection dialog.
    2. Halt the system by pressing <Halt> button.
    3. Download bs_7400_dbg.elf
    4. Press <Go> button to run the bootstrap code just loaded.
    Give it a couple seconds.
    5. Halt the system again.
    6. Download bolo_LLH7a400_10_LCE_strip_RAM
    7. a. open up a tera-term window
    b. Press <Go> button. You should see the Bolo header and
    losh prompt on tera-term.

    Through a tera-term window:

    8. losh> load elf
    9. from 'file' menu, select 'send file'. with bolo_LLH7a400_10_LCE_strip_FLA image
    10. losh> burn
    11. Enter 'y' and 'confirm' when asked if you really want to
    do this.

    THEN:

    Overwriting flash block zero.
