## Makefile-driven BBA creation
|
||||
|
||||
This Makefile will generate a Xilinx A35 chipdb if java, capnproto and
|
||||
capnproto-java are installed.
|
||||
|
||||
### Installing dependencies
|
||||
|
||||
Install java and javac if not already installed:
|
||||
```
|
||||
# Or equivalent for your local system.
|
||||
sudo apt-get install openjdk-10-jdk
|
||||
```
|
||||
|
||||
Install capnproto if not already installed:
|
||||
```
|
||||
# Or equivalent for your local system.
|
||||
sudo apt-get install capnproto libcapnp-dev
|
||||
```
|
||||
|
||||
Install capnproto-java if not already installed:
|
||||
```
|
||||
git clone https://github.com/capnproto/capnproto-java.git
|
||||
cd capnproto-java
|
||||
make
|
||||
sudo make install
|
||||
```
|
||||
|
||||
### Instructions
|
||||
|
||||
Once dependencies are installed, just run "make". This should download
|
||||
remaining dependencies and build the chipdb and build nextpnr if not built.
|
||||
|
||||
#### Re-building the chipdb
|
||||
|
||||
```
|
||||
# Remove the text BBA
|
||||
rm build/nextpnr/fpga_interchange/chipdb.bba
|
||||
# Build the BBA
|
||||
make
|
||||
```
