Wow, can you guide me on what you did?
1) apt install raspberrypi-kernel-headers
2) For Debian 11: git clone https://github.com/encbar5/ASL-DAHDI.git --branch 5.9_kernel
or for previous Debian: https://github.com/ke5gdb/ASL-DAHDI.git --branch 5.9_kernel
3) cd ASL-DAHDI/linux
4) make
5) make install
Did you compile dadhi by yourself?
Yes, using patches as guessed by @WD5M
dadhi will run on armf but not on arm64
I beg to differ. arm64 is the same as aarch64 and I've been running on that since my first SHARI build, so at least the minimal part needed for asterisk does work.
There appears to be some confusion in some of the posts here. Seeing as how DAHDI is a kernel module, it has a strong dependency on the kernel version, but this is not the same as the architecture. I have yet to find something in the code that's dependent on a particular architecture. I'm open to correction if someone does find something, though.
