Basic Bare metal application not loading on Zedboard

Question

Hi,

I'm trying to get a basic led glowing project up using a bare metal application. After I downloading the bit stream and the .elf file, I'm not seeing any change on the Zedboard. Even the uart terminal is blank, even though connection is there. The board jumpers are set to jtag mode! I'm sure there is a pretty simple reason as to what I'm not doing right! But I'm not able to put my finger on it! Can someone please explain!

I finally was able to solve the problem. when we configure the Zynq processor, and select UART 1, the voltage across the bank should be made 1.8. This setting is mentioned in one of the tutorials in the link provided by you. Thank you very much. But I still do not understand why it was working on the other Zedboard and failing in this one. The behavior should have been same in both the Zedboards.
