 # Debug
 
-## Using the Xilinx toolchain
-
-Tested with the ZC706 board.
-
-Run the Xilinx Microprocessor Debugger:
-```shell
-/opt/Xilinx/14.7/ISE_DS/EDK/bin/lin64/xmd
-```
-
-Connect to target (given it is connected and you have permissions):
-```tcl
-connect arm hw
-```
-
-Leave xmd running.
-
-Start the Xilinx version of the GNU debugger with your latest build:
-```shell
-/opt/Xilinx/14.7/ISE_DS/EDK/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gdb zc706
-```
-
-Connect the debugger to xmd over TCP on localhost:
-```gdb
-target remote :1234
-```
-
-Proceed using gdb with `load`, `c`

-
-### 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 ~/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 zynq-rs
-# For ZC706, run:
-./tmux.sh 0
-# For Cora Z7, run:
-./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`.
