AM1806: Cannot program NOR FLASH

Hi

I have a question about the tool “TI Serial Flasher Host Program for OMAP-L138”.

I would like to program NOR FLASH with AM1806.

To do it, I set the following parameters as:

    Target: AM1808 (There is no selection for AM1806, therefore I set AM1808 instead of AM1806)

     Device: NOR

The problem is, erase of NOR FLASH is stopped with the message “Waiting for SFT on the OMAP-L138...”

Is there any missing steps?

Thanks
