OLPC Sound modem

The Easy Way

1. Get DebXO running on a XO with the Terminal Activity
2. Update it as per the DebXO wiki

3. # apt-get install soundmodem ax25-apps ax25-tools

4. # mkdir /etc/ax25/

5. Fake /dev/dsp

   # modprobe snd-pcm-oss

6. # soundmodemconfig

7. configure the settings to your requirements then quit soundmodemconfig
8. insert earplugs :P

9. # soundmodem /etc/ax25/soundmodem.conf

The Right Way

WARNING: This is just a brain dump at the moment

1. Upgrade to the latest official build

2. # yum install soundmodem ax25-apps ax25-tools kernel-devel gcc make ncurses-devel rpmdevtools yum-utils

3. # rpmdev-setuptree

4. # yumdownloader --source kernel

5. # yum-builddep kernel-*.src.rpm

6. # rpm -Uvh kernel-*.src.rpm

7. # cd ~/rpmbuild/SOURCES

8. # tar jxvf olpc-2.6.tar.bz2

9. # cd linux-<version>

10. # cp ../kernel-xo1-custom.config .config

11. # make menuconfig

12. # make modules && make modules_install

    (this might not be required if the rpm works)

    # make binrpm-pkg && rpm -i ~/rpmbuild/RPMS/i386/kernel-*-i386.rpm

    (this might be what is needed)
13. ?maybe?

    # cd /boot/ && rm vmlinuz && ln -s vmlinuz-<your build version> vmlinuz && rm System.map && ln -s System.map-<your build version> System.map

14. reboot

15. # insmod /lib/modules/<your build version>/kernel/net/ax25/ax25.ko

16. # insmod /lib/modules/<your build version>/kernel/drivers/net/hamradio/<protocol>.ko

17. # mkdir /etc/ax25/ && soundmodemconfig

18. insert earplugs

19. # soundmodem /etc/ax25/soundmodem.conf
