[arm-allstar] Alpha test: AllStar including rpt_notch and mdc1200

[David McGough]

Duane,

I've uploaded a updated alpha test copy of the AllStar code released with 
1.02beta. This update includes all the beta code in the 1.02beta version, 
plus I compiled in the rpt_notch and mdc1200 encode/decode functionality.

I -think- this code will run on 1.01 for the RPi2 as well, I HAVE NOT 
TESTED IT AT ALL!

Anyhow, downloading and installing won't clobber what you've already got 
setup. Here are the instuctions:

login as root

cd

wget https://hamvoip.org/alpha-test/hamvoip-allstar-alpha-2016-05-12.tgz

# This mv command may fail. If it fails, no problem, continue. 
mv /usr/local/hamvoip-alpha-test/ /usr/local/hamvoip-alpha-test-save  

cd /

tar xvzf /root/hamvoip-allstar-alpha-2016-05-12.tgz

#-------------------------------------------------------

#Then, to run this test version of asterisk:

/usr/sbin/asterisk -vvvvrgc
stop now

/usr/local/hamvoip-alpha-test/sbin/asterisk

#To connect:

/usr/local/hamvoip-alpha-test/sbin/asterisk -vvvvrcg

Note that the original version of Asterisk/AllStar is still installed and 
untouched and will automatically start after a reboot, unless you change 
the boot script in /usr/local/etc/rc.allstar

I'm interested to get feedback about how this works (or doesn't work!).


Have fun--and, please report back!


73, David KB4FXC
