### 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)
```shell
cd ~/zc706
./build.sh $your_user/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
./tmux.sh
```
Time to run your code with:
```shell
zynq-connect
zynq-restart
c
```
or, for a more succinct experience, (identical to above)
```shell
dc
dr
c
```
After every build on your dev machine, simply run:
```shell
dr
c
```
Sometimes you might need to type `load` after `dr`.
Note, to exit `picocom` hit `ctrl-a x`
