README.md

Build

nix-shell --command "cargo xbuild --release"

Currently the ELF output is placed at target/armv7-none-eabihf/release/experiments

Debug

Using the Xilinx toolchain

Tested with the ZC706 board.

Run the Xilinx Microprocessor Debugger:

/opt/Xilinx/14.7/ISE_DS/EDK/bin/lin64/xmd

Connect to target (given it is connected and you have permissions):

connect arm hw

Leave xmd running.

Start the Xilinx version of the GNU debugger with your latest build:

/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:

target remote :1234

Proceed using gdb with load, c

Using OpenOCD

Running on the ZC706

nix-shell --command "cargo xbuild --release"
cd openocd
openocd -f zc706.cfg

Running on the Cora Z7-10

nix-shell --command "cd experiments && cargo xbuild --release --no-default-features --features=target_cora_z7_10"
cd openocd
openocd -f cora-z7-10.cfg

Loading a bitstream into volatile memory

  openocd -f zc706.cfg -c "pld load 0 blinker_migen.bit; exit"

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)

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:

ssh pi4
cd zc706
./tmux.sh

Time to run your code with:

zynq-connect
zynq-restart
c

or, for a more succinct experience, (identical to above)

dc
dr
c

After every build on your dev machine, simply run:

dr
c

Sometimes you might need to type load after dr.
