Introduce

BAPS stands for Blackfin Asterisk Package System. Software in BAPS system is installed on run time rather than build time. Basically we only need to maintain a kernel with basic functions installed, different applications:zaptel, asterisk, ntp etc are built in different packages and maintain in a remote server.

BAPS base firmware are more easier for developer who want to try different packages or do little changes in the source code.

Base baps commands are:

root:~>ipkg install package_name   //to install the needed package 
root:~>ipkg remove package_name    //to remove the useless package 
root:~>ipkg update            //to check the up to date package list 
root:~>ipkg list_installed    //check what packages are installed in system 
root:~>root ipkg list         //list the available packages in the remote server the ipkg 

remote server ip is configured in the /etc/ipkg.conf file.Rowetel maintain the main ipkg server for IP0X.you can always check the available packages and description via

root:~>root ipkg list
