Build

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

Debug

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

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

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