How to create uImage for SoCrates (EBV) board?

[Altera_Forum]

.> 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:  hitex@ubuntu:~/altera-yocto/build_gsrd-image/tmp/deploy/images$ ls -l total 483188 -rw-r--r-- 1 hitex hitex 114673664 2015-01-20 09:01 altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.cpio -rw-r--r-- 1 hitex hitex 152550400 2015-01-20 09:01 altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.ext3 -rw-r--r-- 1 hitex hitex 117637120 2015-01-20 09:03 altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.jffs2 -rw-r--r-- 1 hitex hitex 56007193 2015-01-20 09:02 altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.tar.gz lrwxrwxrwx 1 hitex hitex 61 2015-01-20 09:01 altera-gsrd-image-socfpga_cyclone5.cpio -> altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.cpio lrwxrwxrwx 1 hitex hitex 61 2015-01-20 09:01 altera-gsrd-image-socfpga_cyclone5.ext3 -> altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.ext3 lrwxrwxrwx 1 hitex hitex 62 2015-01-20 09:03 altera-gsrd-image-socfpga_cyclone5.jffs2 -> altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.jffs2 lrwxrwxrwx 1 hitex hitex 63 2015-01-20 09:02 altera-gsrd-image-socfpga_cyclone5.tar.gz -> altera-gsrd-image-socfpga_cyclone5-20150120131804.rootfs.tar.gz -rw-r--r-- 1 hitex hitex 3379224 2015-01-20 08:42 modules-3.9.0-r1-socfpga_cyclone5.tgz -rw-r--r-- 1 hitex hitex 294 2015-01-20 08:59 README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt lrwxrwxrwx 1 hitex hitex 46 2015-01-20 08:43 vmlinux -> vmlinux-1.0-r1-socfpga_cyclone5-20150120131804 -rw-r--r-- 1 hitex hitex 76221877 2015-01-20 08:42 vmlinux-1.0-r1-socfpga_cyclone5-20150120131804 lrwxrwxrwx 1 hitex hitex 49 2015-01-20 08:42 zImage -> zImage-1.0-r1-socfpga_cyclone5-20150120131804.bin -rw-r--r-- 1 hitex hitex 3202816 2015-01-20 08:42 zImage-1.0-r1-socfpga_cyclone5-20150120131804.bin -rw-r--r-- 1 hitex hitex 3202816 2015-01-20 06:45 zImage-3.9.0 lrwxrwxrwx 1 hitex hitex 49 2015-01-20 08:43 zImage-socfpga_cyclone5.bin -> zImage-1.0-r1-socfpga_cyclone5-20150120131804.bin  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 Image Name: SoC FPGA 2015.01.21 Created: Wed Jan 21 05:20:47 2015 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 3202816 Bytes = 3127.75 kB = 3.05 MB Load Address: 0x00008000 Entry Point: 0x00008000  Now I have created my SD card using my images.

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.
