Unrecognized Machine ID when booting Linux on Zedboard

After following the tutorial "Ubuntu on Zync-7000 SoC" and booting Linux on Zedboard I get the following error:

reading zImage

3002960 bytes read
reading devicetree.dtb

8451 bytes read
## Starting application at 0x00008000 ...

Error: unrecognized/unsupported machine ID (r1 = 0x1fb71dd0).

Available machine support:

ID (hex)        NAME
ffffffff        ARM-Versatile Express
000008e0        ARM-Versatile Express
00000d32        Xilinx Zynq Platform

Please check your kernel config and/or bootloader.

What is the problem here and how can I fix it?

jyotsna,

You're not the first one to run into this problem.

Apparently, u-boot passes a machine ID to the kernel when u-boot tries to load it, and there is a mismatch somewhere. A similar problem happened here: http://www.zedboard.org/content/u-boot-machine-id

Did you compile everything from its source, or use the pre-compiled versions? If you compiled it from scratch, you might need to mess with the device tree (.dts) and add a few strings into the compatible section (as described in the link).

Good luck!
