Jtag boot fail in 7Z010 evaluation board




  Recently we  purchased a zynq z-7010 board and trying to boot with our customized kernel (uImage) and filesystem through Jtag,

We followed below steps in xilinx sdk tool to boot the u-boot,

1. xmd

2. connect arm hw

3. source ps7_init.tcl

4. ps7_init

5. target 64

6. dow -data uImage 0x3000000

7. dow -data uramdisk.image.gz 0x2000000

8. dow -data devicetree.dtb 0x2A00000

9. dow u-boot.elf

10. con

 At the command prompt of the u-boot , we typed the command

      bootm 0x3000000 0x2000000 0x2A00000.

After entering this command we get an error message as

Wrong Image Format for bootm command
ERROR: can't get kernel image!

I am sure kernel image is correct because i generated image.ub from same source and successfully booted through sd-card.

I can able to find some links, but that is for z-7020 board


I could not find any documentation for the purchased kit providing information for jtag boot mode and configuration.

Please, share me the procedure for jtag boot,

Sorry , i dint explain about my development environment in earlier post,

I am not using petalinux-boot command to boot through jtag as explained in quick guide.

I have installed xilinx SDK in windows machine and petalinux development in Ubuntu-16.04.

Once compilation is complete in ubuntu environment ,i  copy those images(fsbl,u-boot,uImage.uramdisk.gz,devicetree.dtb) in to windows xilinx sdk path.

and run the jtag commands as posted earlier.

I have reached out to a more experienced embedded linux engineer to look into you post. Under the boot section of this quick guide i describes the process for Petalinux 2015.4.


Any inputs .
