Lu,<br>
<br>
I see from an earlier post that you're running a 4.19.66-v7+ kernel <br>
version. That's the issue. You must have inadvertently upgraded the kernel <br>
when updating Linux.<br>
<br>
The symptom you're describing (the /dev/dahdi folder completely missing) <br>
is explained by missing dahdi drivers.<br>
<br>
The simplest solution is to down-grade your kernel to the previous <br>
version, which should already have drivers present. That kernel and <br>
supporting files are still probably installed, just inactive.<br>

I’m beginning to wonder if my sd card is in trouble. <br>
I thought I might try to copy that directory from another working image but it won’t let me. <br>
