xtmrctr.h file cannot be found

Former Member

I am trying to complete the helloworld tutorial with the imbedded axi_timer and axi_gpio. This is in Chapter 3 of the Zynq ZedBoard Concepts, Tools and Techniques document. After exporting the design to SDK I cannot compile and run the design because the helloworld.c file calls out an include for the xtmrctr.h file.

Where is this file? It does not seem to be included in the zip file where the tutorial came from and I cannot find it on the xilinx web site either.

Any help would be appreciated.

    Hello Paul,

    When SDK creates the BSP it reads the HW platform and adds the appropriate drivers for each of the peripherals. When you added the axi timer to your hardware design in the previous experiment and exported the design to SDK the new hardware should have been detected and the BSP should have added xtmrctr.h to the project along with the device drivers. You can take a look at the system.mss file (located under Hello_world_bsp in the SDK project if it is not already open), under 'Peripheral Drivers' and see if the axi_timer drivers have been included. If not, this is the problem. If the export of the hardware design to SDK was successful you might try a 'clean' of the SDK projects to see if the BSP will rebuild correctly. Otherwise you might need to go back to Vivado, make sure the design including the axi_timer is 'open' and export the design to SDK again.

    Regards,

    The clean did not help so I took the drastic step of starting from scratch. I get through to the SDK startup and the .mss shows that it has the peripherals installed. I got through a compile, but the output to the screen is simply hello world which is from the original file. I open the helloworld.c file in the SDK editor and it shows the new file and hello is not in the file other than the name, so SDK shows one file but apparently is compiling the old, or is loading the old output file.
