# pmon
pmon2000 git for possible qemu use

Download toolchain from http://www.anheng.com.cn/loongson/pmon/
toolchain-pmon.tar.bz2

Unpack it, copy gcc-2.95 based cross-compiler to /usr
In pmon directory tree compile and install tools  from /tools subdir
{they will go into /opt/pmon2000/tools}

Possibly modify Targets/Bonito2edev/conf/Bonito

cd into zloader.2edev dir, put build script there as well.
Compile it with build.sh script:

#!/bin/bash
export MKDEP=makedepend
export PATH=/usr/local/comp/mips-elf/gcc-2.95.3/bin/:$PATH
make cfg            #ёьРВЕдЦГ
make tgt=ram
mv gzram pmon_ram.bin
make tgt=rom    #ІъЙъЙХЦЖОДјю gzrom.bin
mv gzrom.bin  pmon.bin
mkdir -d /var/lib/tftpboot
cp pmon.bin pmon_ram.bin /var/lib/tftpboot

LANG=C ./build.sh

there must be pmon.bin file in this directory.
Use it with fresh (4.0+) qemu like this:

qemu-system-mips64el -M fulong2e -bios /dev/shm/pmon/zloader.2edev/pmon.bin
