### Development Process
Clone this repo onto your development/build machine and the raspberry pi that controls the Xilinx 7000 board
On the dev machine, the below script builds zc706 and secure copies it to the target pi (in your pi $HOME directory)

It's nixbld.m-labs.hk (not nixbuild...), and also the script does copy it to a RPI using the IPv4 port redirects. We should change the script to use the rpi IPv6 hostname.

Fixed in harry/zynq-rs:b6919d1730, but the updated build.sh has not been tested from outside.

Fixed in harry/zynq-rs:https://git.m-labs.hk/harry/zynq-rs/commit/b6919d1730889fcaf35ebfb17bac7e888f1edb77, but the updated build.sh has not been tested from outside.
```shell
cd ~/zc706
./build.sh $your_user/ssh_id
cd ~/zynq-rs
./build.sh $your_user_or_ssh_id
```
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:
```shell
ssh pi4
cd zc706
cd zynq-rs
# For ZC706, run:
./tmux.sh 0
# For Cora Z7, run:
./tmux.sh
```

-6 will not work with -P 2204 nor is it needed otherwise. It's either -P 2204 nixbld.m-labs.hk or rpi-4.m-labs.hk.

So are we to abandon the use of nixbld.m-labs.hk altogether and use rpi-4 only instead?

Yes the port redirect on nixbld is only a workaround for people who don't have IPv6.
