    v7 v8  
    88Before using a WARP reference design XPS or SDK project you must install the Xilinx tools and configure repository settings:
    99
    10  * Install Xilinx ISE 13.4 System Edition (includes ISE, EDK, System Generator)
     10 * Install Xilinx ISE
     11   * To simulate or modify the FPGA design you need System Edition (includes ISE, EDK, System Generator)
     12   * To only change C code you can use the SDK-only editions of ISE
    1113 * Checkout a copy of the WARP edk_user_repository to a local directory
    1214 * Add the WARP edk_user_repository to the global repositories in XPS (Edit->Preferences->Application) and SDK (Xilinx Tools->Repositories->Global Repositories). Close both XPS and SDK.
    1315
    1416=== Project Files ===
    15 Download either reference design .zip file from the [wiki:OFDMReferenceDesign/Changelog OFDM Reference Design download page] or the [wiki:WARPLab/Releases WARPLab OFDM Reference Design download page].
     17Download the reference design .zip file.

    1719The ref design archive includes both the XPS project (i.e. the hardware design) and SDK projects (i.e. the software designs). The archive folder structure is:
    … …  
    1921SDK/
    2022 |- SDK_Export/
    21 SDK_PROJECTS_IMPORT/
     23SDK_Workspace/
    2224data/
    2325etc/
    2426pcores/
    25 workspace/ *this folder is intentionally empty for the user to create his or her workspace in*
    26 platgen.opt
    27 system.make
    2827system.mhs
    2928system.xmp
    30 system_incl.make
    3129}}}
    3230
    … …  
    3836 * The hardware specification (auto-generated by XPS)
    3937 * The board support package (auto-geneated by SDK, derived from the hardware spec)
    40  * Software projects (user code in an SDK-generated template)
     38 * One ore more software projects (user code in an SDK-generated template)
    4139
    4240We have chosen the approach of having one SDK workspace per XPS project, so the SDK workspace always contains exactly one _hw_platform project and one _bsp project, both referenced to the parent XPS project.
    … …  
    4442A workspace always maps to a folder on your hard drive. That folder will contain workspace settings (in a {{{.metadata}}} directory) and subdirectories for each project in the workspace.
    4543
    46 Unfortunately workspaces are not portable. The ref design .zip file contains all the necessary project files to populate a workspace, but you must initialize your workspace first and import these project files manually. We recommend using the blank workspace folder in the root directory of the XPS project.
     44Unfortunately workspaces are not portable. The ref design .zip file contains all the necessary project files to populate a workspace, but you must initialize your workspace first and import these project files manually. We recommend using the SDK_Workspace folder inside the XPS project folder as your SDK workspace.
    4745
    48 In the instructions below we use {{{<xps_proj>}}} to represent the path where you expanded the ref design .zip. If the XPS project file is in {{{C:\work\WARP\OFDM_RefDesign_FPGAv2_v17.0\system.xmp}}}, then you should use {{{C:\work\WARP\OFDM_RefDesign_FPGAv2_v17.0\}}} in place of {{{<xps_proj>}}} below.
     46In the instructions below we use {{{<xps_proj>}}} to represent the path where you expanded the ref design .zip. If the XPS project file is in {{{C:\work\WARP\OFDM_RefDesign_FPGAv2_v18.1\system.xmp}}}, then you should use {{{C:\work\WARP\OFDM_RefDesign_FPGAv2_v18.1\}}} in place of {{{<xps_proj>}}} below.

    5048'''Creating the workspace'''
    5149 * Launch the Xilinx SDK
    52    * If prompted to select a workspace, choose {{{<xps_proj>/workspace}}}
    53    * If not, choose File->Switch Workspace, then choose {{{<xps_proj>/workspace}}}
     50   * If prompted to select a workspace, choose {{{<xps_proj>/SDK_Workspace}}}
     51   * If not, choose File->Switch Workspace, then choose {{{<xps_proj>/SDK_Workspace}}}
    5452 * Choose Xilinx Tools->Repositories
    5553   * Verify the WARP edk_user_repository is listed in the Global Repositories section
    … …  
    5755   * Click OK
    5856 * Choose File->Import, expand General, choose Existing Projects into Workspace, click Next
    59    * For 'Select root directory:', click Browse and navigate to {{{<xps_proj>/SDK/SDK_PROJECTS_IMPORT}}}
     57   * For 'Select root directory:', click Browse and navigate to {{{<xps_proj>/SDK_Workspace}}}
    6058   * Make sure all projects are selected
    61    * Make sure "Copy projects into workspace" is checked... this will move them out of the temporary import folder into your workspace
     59   * Make sure "Copy projects into workspace" is not checked
    6260   * Click Finish
    6361 * SDK will begin building the software projects. If everything works, this process will finish with a log message {{{'elfcheck passed'}}}.
    64  * In the Project Explorer tab right-click the user software project and choose Generate Linker Script
    65    * On WARP v2, assign Code Sections to iocm, Data sections to docm, Heap/Stack to xps_bram_if_cntlr_1. On WARP v3, assign Code Sections to xps_bram_if_cntlr_0, Data to xps_bram_if_cntlr_1 and Heap/Stack to to ilmb_cntlr_dlmb_cntlr. It is critical no sections be assigned to xps_bram_if_cntlr_2 (this BRAM is the PHY pkt buffers).
    66    * Change Heap/Stack sizes to 4096 (4K)
    67    * Click Generate; click Yes to overwrite existing linker script

    70 '''Running the design''' ''Brief instructions, to be elaborated soon''[[BR]]
    71 Program the FPGA:
    72  * Connect the JTAG cable
    73  * Xilinx Tools->Program FPGA
    74    * Choose bootloop
     63'''Running the design'''
     64Program the FPGA from SDK:
     65 * Connect the JTAG cable to your FPGA board
     66 * In the SDK select Xilinx Tools->Program FPGA
     67   * In the Software Configuration section, select the ELF file corresponding to your top-level software application
    7568   * Click Program
    76  * Wait ~20 seconds; FPGA Board should now be configured (green DONE LED on, red Radio Board PLL unlocked LEDs on)
    77 
    78 
    79 Download the software program:
    80  * Click on the user software project in Project Explorer
    81  * Choose Run->Run
    82  * Software should now be running (FPGA Board hex displays on, Radio Board Rx LEDs on, PLL unlocked LEDs off)
    83  * Connect serial cable (57600bps) to monitor STDOUT
    84 
    85 '''Iterating on software''' ''Brief instructions, to be elaborated soon''[[BR]]
    86 FPGA only needs to be configured once; software iterations only require re-running the code[[BR]]
    87  * Make desired changes to source code
    88  * Verify compilation succeeds (watch for {{{'elfcheck passed'}}})
    89  * Click on the desired project, Run->Run; if prompted "Target processor is currently in use", click Yes.
    90 
    91 '''Debugging software''' ''Brief instructions, to be elaborated soon''[[BR]]
    92  * Same preparation as running software
    93  * Choose Run->Debug (instead of Run->Run) to enter debug mode
     69   * Wait ~20 seconds; the FPGA should now be configured (green DONE LED on)

    … …  
    9874Some helpful things we've figured out:
    9975
    100  * Do not power cycle the FPGA Board or disconnect the JTAG/USB cable while SDK is running. Always quit SDK first.
     76 * Do not power cycle the FPGA Board or disconnect the JTAG/USB cable while the SDK debugger is running. Always quit SDK first.
    10177   * If an active SDK session loses the JTAG connection, the JTAG cable will get locked and will fail to function for the current or future SDK sessions. The SDK may freeze in this state. Use Task Manager to kill eclipse.exe and xmd.exe. Then run iMPACT (Programs->Xilinx Design Suite 13.4->ISE Design Tools->32/64-bit Tools->iMPACT), double-click Boundary Scan, choose Output->Cable Reset. Then re-launch SDK to reestablish the JTAG connection.

    124  Here, {{{'old_project_name'}}} will be the name of the hardware project that you imported from-- not necessarily the name of the hardware project in your current workspace. This name is populated in the properties for your software project under C/C++ Build->Settings->Tool Settings Tab->Xilinx ELF Check->Options->Hardware Specifications. You can manually update that string, or you can simply right click on your software project and {{{'Change Referenced BSP'}}} then simply hit {{{'OK'}}}. That's enough for the SDK to reach into the BSP and update that field with the proper string.
     100This usually indicates the software project is referencing an old BSP, which was based on a different hardware project. Right click on your software project and {{{'Change Referenced BSP'}}} and double-click the correct BSP to re-associate the software project.
