Garbled text just means the Baud rate (default = 115200) of your PC software is incorrect. Click :ref:`here` if you get "Stair Stepping" of text. .. note:: If you're using a binary image from the same family, even if the exact part number is not listed in the :ref:`supported MCU types`, chances are very good it is actually working but for one of the possible reasons below. Possible Causes --------------- ============== ================================================================================================== ===================================================== Possible Cause Remedy Page ============== ================================================================================================== ===================================================== Wrong USART Try other USART pins on the chip. Test by resetting the MCU and look for the Greeting message :ref:`Serial connections` Memory Config Having less memory on your chip than the image you're using can cause a silent crash :ref:`Memory` Boot Selection Is the chip booting from Flash ? :ref:`Boot Selection` Bad Flash Are you telling your flasher to verify the image was burned correctly ? :ref:`Flashing Methods` ============== ================================================================================================== ===================================================== Finally ------- If you need help the Mecrisp-Stellaris community has a lot of experts, so once you have *tried everything*, email the mailing list at: https://sourceforge.net/projects/mecrisp/
