But when i made a boot image for booting from sd card it is not booting and fpga done led also not glowing. Pls help me.
Carrier Card Generic Guidelines are here:
As far as layout is concerned, the SOM routing of the BANK 501 MIO signals to the JX connector are all length matched. So, guidance for the layout of the carrier card can follow the guidance provided in the Zynq-7000 PCB Design Guidelines. Zynq-7000 SoC PCB Design Guide (UG933) • Viewer • AMD Technical Information Portal
Here is schematic from PicoZed Carrier for SD card. Did you reference/copy this?
