initial booting

sungyung_lim

We purchased a MMP with zynq 7z100.
Since we followed the simple instruction,
we found that the initial serial connection didn't work.
We used sd card-based booting with factory-installed linux image. Is there any known defect on instruction or linux image? And is there any useful information on it?

Thank you for your consideration in advance.

    Hello S.Y.

     

    The Getting Started Guide is applicable to the 7Z100 as well. You will need a different boot image for the 7z045 board vs the 7x100 board. The Config_Done LED (D1) on the BaseBoard should light if the device is configured correctly. If you need you can download each image from the Zynq MMP Reference Designs page:

    I am not sure what you mean by 'swapping zynq chips'. If this means that the serial connection works with a 7z045 MMP board but not with the 7z100 MMP board you should be aware that each Silicon Labs CP210x USB UART device will enumerate individually, so if the Comm port is '6' for one of the boards, it will some other Comm port number (such as '7') on the other board. You would need to have a different instance of your terminal program (such as Tera Term or Putty).

    Thank you Gary. The linux image downloaded from the website (with planAhead) has a serial connection work.

    I have two more questions:

    1. we use vivado 2014.2 that is compatible with matlab 2015a. I'm wondering whether the image with vivado 2014.2 is available.

    2. I cannot establish Ethernet connection between pc and zynq 7z100. We use a USB Ethernet card with a router. Do I need some additional steps ?

    Thank you so much. S. Y.
