Ubuntu - the board does not boot from provided BOOT.bin

Former Member

Hi,

I have the Zynq Mini-ITX 7Z100 and currently I am trying to get the Ubuntu Linux to run.
I downloaded the "Zynq Mini-ITX 7Z100 Ubuntu v2014.4" package containing all the necessary files and went through the tutorial, in order to generate the needed BOOT.bin file. Everything worked out great, but the board does not boot from the sd card containing the generated boot file at all.
Neither the provided files for the sd card are working.

Also I have tried out the "Zynq Mini-ITX 7Z100 Ubuntu v2013.4" package and the supplied files from there, but the result is the same.

I donu00B4t get any response on the terminal and the blue LED does not illuminate.

The only thing that works, is the out of the box image from the package "Zynq Mini-ITX 7Z100 Out-of-Box Linux v2013.4".
Using the files provided in this package I am able to boot.
I get the blue LED and a prompt on the terminal.


Can someone please help? How can I generate a BOOT.bin file that will work, so I can then boot Ubuntu? I am doing everything that the tutorial describes.

Thank you in advance

    Hi Andrej,

      Very curious indeed.  The partitioning of the SD card should make no difference in the initial boot, as long as there is a FAT32 partition where the boot.bin file can be read from.  At this stage you don't care about the ext4 partition at all, so you could use any compatible SD with a FAT32 partition.

      I use SanDisk SD/microSD cards exclusively, because I have never had a failure with one.  For Ubuntu, since the ext4 partition resides on the card, I like to use the SanDisk Ultra with 30 mbps transfer rate, as it gives a little better performance when working with the desktop environment.  I created my card by following the Ubuntu tutorial instructions.  These have been verified in many different instances, and they definitely should work just fine. 

    You can eliminate the partitioning issue by using a new microSD card, which are generally preformatted to FAT32.  Just copy the Ubuntu boot.bin file to that, and see if the DONE LED and Ubuntu output appears.  If possible, try using a SanDisk microSD.  I consulted with a colleague, and he says there is a possibility that if a card is marginal, one boot.bin file could work while another does not.  I have not seen that myself, but it would be good to eliminate the possibility.
