============================================================================================================
The above code is what gives Zedboard in document ZedBoard: Zynq-7000 AP SoC Concepts, Tools, and Techniques, in section Reference Designs / Tutorials. This code gives me errors in a series of "constant" as:
- XPAR_AXI_TIMER_1_DEVICE_ID
- XPAR_AXI_GPIO_1_DEVICE_ID
The error it complaining :#include "xtmrctr.h" and #include "xgpio.h"
 Why this error occurs? should I use the same version of my vivado and SDU according to my zedboard?
Thank you very much

Hi Sarah,

Hi Sarah,

For you first question about the two Devic ID's please refer to this post http://zedboard.org/content/zedboard-problem-code-sdk

For the error compaining about xtmrctr.h and xgpio.h. Please refer to this detailed solution https://forums.xilinx.com/t5/Embedded-Development-Tools/Can-t-find-xgpio...

About your question of "should I use the same version of my vivado and SDU according to my zedboard?" the answer is yes, you should always use the same version of Vivado to version of SDK. For instance if you are using Vivado 2016.4 you should also be using SDK 2016.4
