Zedboard booting up issue

Former Member

Hi,

Working with xillinux linux distribution to boot the zedboard I have a problem.

1.The board boots fine works well but hangs up frequently.

2. On re-boot the boot loader displays a message that there is an error while decompressing the kernel image and stops booting.

3. Each and every time even after properly shutting down the board this error happens and the board boots up fine if the boot partition is formatted and freshly created again.

Can any one please suggest why this is happening with the board
working with Z7000 APSoC

    Hello,

    Problems with booting and/or startx have been reported repeatedly, and have so far turned out to be a data integrity issue: SD cards other that Sandisk corrupted the data, which lead to random failures. The only special thing with the X server is that it consumes a lot of data from the disk as it goes up, which is why it's likely to be the first opportunity to notice that the SD card is corrupted.

    So I insist on Sandisk not for the speed, but for the reliability. The X server is installed fine.

    Now, since you're saying that you are already using Sandisk, the next step is to suspect data corruption of the DDR memories or an issue with the MMC interface's driver in Linux.

    So I suggest a shot in the dark -- there are two versions of Xillinux out there, 1.1 and 1.3. Whatever version you tried now, please switch to the other, and see if that matters. It shouldn't, but if it does -- it would be interesting to know about it.

    See http://xillybus.com/doc/old-xillinux-zedboard for more information about Xillinux' versions.

    Hi Eli,
    As you suggested I was using 1.3 Version of xillinux previously and replaced it with 1.1 Version. Surprisingly the zedboard is really stable and X server is working perfectly fine. I kept the display up running for more than 5 hrs and the performance did not really degrade. Also rebooted the board a few times and it is booting up perfectly.

    So changing from V 1.3 to V 1.1 solved the stability problem for me.
