Not able to boot Linux from SD card

Hi all,

I am trying to boot Linux from SD card on a Zedboard rev C. I'm able to successfully boot Linux using the files provided with the Zedboard (OOB design), but not with those generated by PetaLinux. I know for sure that the image created by PetaLinux works correctly as I have used it many times on a different Zedboard. I have also checked that all the jumpers are in the correct position.

Any ideas or suggestions?

Thanks,

David

I will ask our SW guys about PetaLinux version 2014.2.

All rev D Zedboards have production silicon. I suppose it is possible that some rev C Zedboards are not ES silicon. You could check the silicon rev for both of your rev C ZedBoards and see if they are the same. Per UG585, the Zynq TRM (http://www.xilinx.com/support/documentation/user_guides/ug585-Zynq-7000-TRM.pdf ) on page 1160, you can read the MCTRL register and retrieve the silicon rev.

To read the MCTRL Launch an XMD console in SDK and then connect to the ARM "connect arm hw" and then read the register with a memory read command "mrd 0xF8007080". The MS 4 bits are the silicon rev. Rev 3 or higher (0x2 or 0x3) is production silicon.
