avnet mini itx board u-boot problem

Former Member
Former Member over 10 years ago

Hi
I have an u-boot problem on avnet zynq mini itx board:

I rebuild the latest u-boot image fromuFF1Agit clone git://git.xilinx.com/u-boot-xlnx.git, and found that sometimes it boot fail on my Avnet mini itx board(Mini-itx-7z-asy-g), it may hang in boot early stage like below:

U-Boot 2014.01-dirty (Jun 24 2014 - 15:29:02)

I2C: ready
Memory: ECC disabled
DRAM: 1 GiB
MMC: zynq_sdhci: 0
SF: Detected S25FL128S_64K with page size 512 Bytes, erase size 128 KiB, total 32 MiB

Of course, the pre-flash u-boot(U-Boot 2013.01-dirty) in the SD card from the vendor does not have the problem, and I have a "2013.04" version, it does not have the problem either.

It should be a software issue and it seems that the later u-boot version have the problem. And I also test the 2014.01-dirty version on ZC706 board, it does not have the problem.

Would you please help me with this problem? Thanks!

    There is a working u-boot image for the Mini-ITX board as part of the PetaLinux 20914.2 BSP posted here:

     

    http://microzed.org/support/design/2056/17

     

     It was generated by the PetaLinux tool chain.

    Hi Gary

    Thanks for your help, I do not only need the working u-boot image but also the latest u-boot source code, as I want to change the u-boot code to re-make a u-boot image. Would you please tell me how can I get the u-boot source code for mini itx and the steps to rebuild it? Thanks!

    There are details in Xilinx UG976 and the Avnet 2014.2 PetaLinux reference design that describe the PetaLinux development steps. Once you have completed your PetaLinux project the U-boot source code should be there.

     

    Or you can extract the u-boot source from the Xilinx gihub. There are instructions on how to do that in the Mini-ITX Ubuntu tutorial.

     

    Both the Mini-ITX PetaLinux Reference design and the Ubuntu tutorial can be downloaded here: http://www.zedboard.org/support/design/2056/17
