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 Connected to libftdi driver. Found device ID: 0x0362d093 r0: 0000000000001094 r1: 0000000000001ed0 r2: 000000000000a000 r3: 0000000000000003 r4: 000000000000000d r5: 00000000ffff2ca5 r6: 00000000ffff3eb8 r7: 0000000000000000 r8: 00000000ffff3c33 r9: 0000000000000003 Core: running NIA: 00000000000011d4 MSR: 8000000000000001 ``` ## 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" $ mw Connected to libftdi driver.
