Bootloader tutorial

Former Member

We're trying to do the bootloader tutorial on (http://www.zedboard.org/sites/default/files/design/Zedboard_boot_guide_IDS14_1.zip).  We're able to make a BOOT.BIN and boot it from the sdcard, however we're failing to get it into the QSPI.

Using zed-boot, the erase takes the expected amount of time (a minute?) but the write takes under 5 seconds, and upon powering up the DONE light illuminates instantly.

We tried using both 14.1 and 14.3.

We also tried using SDK's Program Flash option (in 14.3, as it's documented to be nonfunctional in 14.1) also to no avail.

Any ideas? TIA.

    Hi awhill,

    Sounds like you may actually be having some success if the done light is coming on.  I just tried this on my ZedBoard with 14.3 tools and saw the same thing as you.

    I went over to the terminal window and started hitting keys when I saw this:

    Selection : d

    It looks like ZedBoard boots up so fast from QSPI that the USB-UART device does not have enough time to enumerate with Windows and register with the terminal window so you will miss the application banner when the application starts.

    After you power on and see the blue done light come on, go to your terminal window and press the '1' key.  This should get you into the application actions and you should be able to experiment with the application.

    Regards,
