mw_debug is the microwatt debugger.
|
||
|
|
|
||
|
|
It can talk to the simulator using a socket.
|
||
|
|
|
||
|
|
On an Arty board it uses the FTDI device via liburjtag.

## Building on Fedora
|
||
|
|
|
||
|
|
```
|
||
|
|
dnf install urjtag-devel
|
||
|
|
make
|
||
|
|
```
|
||
|
|
|
||
|
|
If you commonly use it against one target, create an alias as follows:
|
||
|
|
```
|
||
|
|
alias mw="$HOME/microwatt/scripts/mw_debug/mw_debug -b jtag"
|
||
|
|
$ mw gpr 0 10

## Building on Debian
|
||
|
|
|
||
|
|
Debian disables the library in the urjtag package. Instead, build against
|
||
|
|
local urjtag:
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo apt install libftdi-dev
|
||
|
|
git clone https://git.code.sf.net/p/urjtag/git urjtag
|
||
|
|
cd urjtag/urjtag
|
||
|
|
./autogen.sh
|
||
|
|
make
|
||
|
|
```
|
||
|
|
|
||
|
|
And then uncomment the following line in Makefile to build against that copy
|
||
|
|
|
||
|
|
```
|
||
|
|
CFLAGS += -I urjtag/urjtag/include/ -L urjtag/urjtag/src/.libs/
|
||
|
|
```
|
||
|
|
|
||
|
|
To run:
|
||
|
|
```
|
||
|
|
alias mw="LD_LIBRARY_PATH=$HOME/microwatt/scripts/mw_debug/urjtag/urjtag/src/.libs/ $HOME/microwatt/scripts/mw_debug/mw_debug -b jtag"
