| 2 | 5 | h1. Building FPGA and ZPU images |
|

| 4 | 1 | ||
| 5 | 5 | It's generally not necessary to build FPGA and ZPU images, as stable builds can be downloaded from "people.osmocom.org":http://people.osmocom.org/ipse/umtrx-v2/current/. |
|
| 6 | 1 | ||
| 7 | 5 | These instructions are for if you want to _participate_ in ZPU/FPGA development. |

| 10 | h2. Building ZPU firmware and bootloader |
||
| 11 | |||
| 12 | |||
| 13 | 2 | 1. Get the latest stable version of ZPU toolchain: http://opensource.zylin.com/zpudownload.html |
|
| 14 | 1 | 2. Build the firmware and the bootloader: |
|
| 15 | 5 | <pre> |
|
| 16 | 1 | mkdir <UHD-dir>/firmware/zpu_build |
|
| 17 | cd <UHD-dir>/firmware/zpu_build |
||
| 18 | export PATH=$PATH:<path-to-zpu-elf-gcc> |
||
| 19 | cmake ../zpu |
||
| 20 | make |
||
| 21 | 5 | </pre> |
|
| 22 | 1 | ||
| 23 | |||
| 24 | |||
| 25 | 5 | h2. Building the FPGA |
|
| 26 | |||
| 27 | |||
| 28 | 1 | 1. Setup Xilinx tools environment: |
|
| 29 | 5 | <pre> |
|
| 30 | 1 | . /opt/Xilinx/14.2/ISE_DS/settings64.sh |
|
| 31 | 5 | </pre> |
|
| 32 | 1 | 2. Update the ZPU bootloader: |
|
| 33 | 5 | <pre> |
|
| 34 | 1 | cp <UHD-dir>/firmware/zpu_build/usrp2p/bootloader/bootloader.rmi <UHD-path>/fpga/usrp2/top/N2x0/bootloader_umtrx.rmi |
|
| 35 | 5 | </pre> |
|
| 36 | 1 | 3. Go to the FPGA part of UHD and build: |
|
| 37 | 5 | <pre> |
|
| 38 | 1 | cd <UHD-path>/fpga/usrp2/top/N2x0 |
|
| 39 | 5 | make [[UmTRX]] |
|
| 40 | </pre> |
||
| 41 | 1 | ||
| 42 | |||
| 43 | |||
| 44 | 5 | h2. Flashing images |
|
| 45 | |||
| 46 | |||
| 47 | Once the build is completed images can be "flashed to [[UmTRX]]":http://umtrx.org/hardware/flashing/. |
