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>

equally there should now be a lot of /proc/net/wanrouter/ files

<pre>

$ cat /proc/net/wanrouter/hwprobe
