On the dev machine, the below script builds zc706 and secure copies it to the target pi (in your pi $HOME directory) On the dev machine, the below script builds zc706 and secure copies it to the nixbuild.m-labs.hk server:
```shell ```shell
cd ~/zc706 cd ~/zynq-rs
./build.sh $your_user/ssh_id ./build.sh $your_user_or_ssh_id
```
Alternatively, you may copy the zc706 build to the target pi (in your pi $HOME directory, for example) using:
```shell
cd ~/zynq-rs
scp -C target/armv7-none-eabihf/release/experiments your_user_or_ssh_id@pi_hostname:/home/your_user_or_ssh_id/zynq-rs/zc706.elf

On the pi, we need an information rich environment that includes a relatively reliable `gdb` experience (that includes `ctrl-p` and `ctrl-n` command history that persists across `cgdb` executions), run: On the pi, we need an information rich environment that includes a relatively reliable `gdb` experience (that includes `ctrl-p` and `ctrl-n` command history that persists across `cgdb` executions), run:
