h1. Sangoma Wanpipe DAHDI
some random notes on bulding DAHDI drivers for Sangoma AFT104 cards on a modern Debian 11 / buster
h2. Sources
* wanpipe 7.0.34 (e.g. via https://git.osmocom.org/wanpipe)
* dahdi-linux (e.g. https://github.com/osmocom/dahdi-linux)
h2. Building
# build + install dahdi-linux
#* usual make + sudo make install
h3. building sangoma wanpipe drivers
<pre>
$ cp ~/dahdi-linux/drivers/dahdi/Module.symvers ~/wanpipe/patches/kdrivers/src/net
$ make -j4 dahdi DAHDI_DIR=/home/laforge/dahdi-linux KBUILD_EXTRA_SYMBOLS=/home/laforge/dahdi-linux/drivers/dahdi/Module.symvers
</pre>
the importance is to pass the correct Module.symvers from the DAHDI build as KBUILD_EXTRA_SYMBOLS, as otherwise the wanpipe drivers will fail to load with errors like this:
This somehow fails, the Module.symvers gets overwritten and the module fails with various related errors:
<pre>
[ 4874.442680] wanpipe: no symbol version for dahdi_hdlc_putbuf
[ 4874.442702] wanpipe: Unknown symbol dahdi_hdlc_putbuf (err -22)
[ 4874.442754] wanpipe: no symbol version for _dahdi_ec_span
[ 4874.442760] wanpipe: Unknown symbol _dahdi_ec_span (err -22)
..
</pre>
h2. Loading
If you want to manually load the modules
* @modprobe dahdi@ (assumption is that dahdi is already installed to @/lib/modules/@)
* from within@wanpipe/patches/kdrivers/src/net@
** @insmod sdladrv.ko@
** @insmod wanrouter.ko@
** @insmod wanpipe.ko@
you should then see something like this below (my system has two AFT-104-SH cards installed):
<pre>
[ 5890.715722] WANPIPE(tm) Multi-Protocol WAN Driver Module 7.0.34.0 (c) 1994-2016 Sangoma Technologies Inc

equally there should now be a lot of /proc/net/wanrouter/ files
<pre>
$ cat /proc/net/wanrouter/hwprobe
