============================================================================================================

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 gives is:

undeclared (firts use In this function)

Why this error occurs? What value should have these constants?

Thank you very much

Undeclared error

Depending on the version of Xilinx tools, or other implementation issues, the axi_gpio and axi_timer modules you added to your design may be enumerated starting with a '0' or a '1'. Take a look in the xparameters.h file (in the include directory under your Hello_world_bsp) and see if your modules were defined as XPAR_AXI_GPIO_1_DEVICE_ID and XPAR_AXI_TIMER_1_DEVICE_ID, as the application code is expecting, or  as XPAR_AXI_GPIO_0_DEVICE_ID and XPAR_AXI_TIMER_0_DEVICE_ID instead. If this is the case, just modify the application c code to match the values in the xparameters.h file.

Error Solved

Thank you, Gray

SDU

I am trying to run this on my zedboard but I got errors which shows that SDK complaining about these two libraries #include "xgpio.h"
#include "xtmrctr.h". Anyone could help me???????
