How to create uImage for SoCrates (EBV) board?

.> admin : sorry I have posted the same question on the wrong place ( in NIOS Linux).

I'm a Linux/SoC beginner and trying to generate my Linux environment for the SoCrates board from EBV.

In the first step I have created an SD card using the pre-build images and script from socrates-training. This works fine.

I have finished the installation (linux-socfpga-gsrd-13.1-src.bsx) and build process without any errors but the generation process has created only a zImage and no uImage. I found following files as result of my build process:

As the result my searches I have created my uImage using following script:

root@ubuntu:/home/hitex/soc_1# mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n "SoC FPGA 2015.01.21" -d zImage uImage

Now I have created my SD card using my images. The boot process stops after the message "Starting kernel ...":

In the 2nd step I have copied the original uImage from socrates-.training and the system has bin started.

My generated uImage is definitely defeat!

I have also generated the kernel as described here: http://www.alterawiki.com/wiki/compiling_u-boot_and_linux_kernel_for_cyclone_v_soc. Same result :mad:

Please help me! How can I create a working uImage?

    solved. After generating a new device tree file (dtb) linux is booting.
