| 3 | 2 | It's generally not necessary to build FPGA and ZPU images, as stable builds can be downloaded from [http://people.osmocom.org/ipse/umtrx-v2/current/ people.osmocom.org]. These instructions are for you only if you want to participate in ZPU/FPGA part development. |
|
| 4 | 1 | ||
| 5 | == Building ZPU firmware and bootloader == |
||
| 6 | |||
| 7 | 2 | 1. Get the latest stable version of ZPU toolchain: http://opensource.zylin.com/zpudownload.html |
|
| 8 | 2. Build the firmware and the bootloader: |
||
| 9 | 1 | {{{ |
|
| 10 | mkdir <UHD-dir>/firmware/zpu_build |
||
| 11 | cd <UHD-dir>/firmware/zpu_build |
||
| 12 | export PATH=$PATH:<path-to-zpu-elf-gcc> |
||
| 13 | cmake ../zpu |
||
| 14 | make |
||
| 15 | }}} |
||
| 16 | |||
| 17 | |||
| 18 | 2 | == Building the FPGA == |
|
| 19 | 1 | ||
| 20 | 2 | 1. Setup Xilinx tools environment: |
|
| 21 | 1 | {{{ |
|
| 22 | . /opt/Xilinx/14.2/ISE_DS/settings64.sh |
||
| 23 | }}} |
||
| 24 | 2 | 2. Update the ZPU bootloader: |
|
| 25 | 1 | {{{ |
|
| 26 | cp <UHD-dir>/firmware/zpu_build/usrp2p/bootloader/bootloader.rmi <UHD-path>/fpga/usrp2/top/N2x0/bootloader_umtrx.rmi |
||
| 27 | }}} |
||
| 28 | 2 | 3. Go to the FPGA part of UHD and build: |
|
| 29 | 1 | {{{ |
|
| 30 | cd <UHD-path>/fpga/usrp2/top/N2x0 |
||
| 31 | make UmTRX |
||
| 32 | }}} |
||
| 33 | |||
| 34 | |||
| 35 | == Flashing images == |
||
| 36 | |||
| 37 | When you're done with build, you could flash your images to UmTRX flash. For the process see [wiki:FlashingUmTRX]. |
