Ubuntu Desktop Linux on Zedboard

Former Member

Hello,

I have tried to build and run the Reference design
Ubuntu Desktop Linux (http://www.zedboard.org/sites/default/files/design/Ubuntu_on_Zedboard_Tutorial_v14.4_02.pdf),
but I get the following message in TeraTerm when booting:

reading uImage
2880430 bytes read in 414 ms (6.6 MiB/s)
reading devicetree.dtb
8451 bytes read in 14 ms (588.9 KiB/s)
## Booting kernel from Legacy Image at 03000000 ...
   Image Name:   Linux kernel
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    2880366 Bytes = 2.7 MiB

   Entry Point:  00008000
   Verifying Checksum ... OK
## Loading init Ramdisk from FIT Image at 02a00000 ...
Bad FIT ramdisk image format!
Ramdisk image is corrupt or invalid

Is something wrong with the ext4 partition that I created as described in the Reference or is it something else (i.e in the uImage, devicetree, etc)?

Thanks in advance

    I searched the web, and I found out that the uImage is not properly compressed or compiled... I get the following error:

    Wrong Ramdisk Image Format

    I used mkimage to build the uImage file after the compilation of the kernel, as described in the Reference
