Pi 4 Dragon OS - Problem with latest build

Attempted to build from github clone this morning. Running the install script failed with code errors in CaribouLiteCpp.hpp as there were classes not included that were required. I added the "#include " statement as suggested by the build system. Once this was added, everything loaded properly.

Prior to running the install script, I commented out line 29 which loaded headers line for raspbian and left the one for ubuntu intact.

Next I updated the config.txt file as noted both in #94 and by the output of the install script.

On running SoapySDR --find and/or SoapySDR --probe, it finds the caribou board, but is failing on reading the fpga as follows (Note: I did add the "dtoverlay=spi1-3cs" line at the end of the config.txt file to allow communications). It appears that /dev/smi is not getting set up properly, even though lsmod shows the driver is present.

~$ sudo lsmod | grep smi
bcm2835_smi            24576  0

$ sudo SoapySDRUtil --find

Any suggestions would be greatly appreciated. Is there perhaps another repository I should be using?

Looking at the system log, I find the following:

Nov 30 15:44:28 ubuntu systemd-modules-load[355]: Failed to find module 'smi_stream_dev'
Nov 30 15:44:28 ubuntu kernel: [    7.399340] smi-bcm2835 fe600000.smi: initialised

The module smi_stream_dev exists in the build directory, but is not being found by the system. Perhaps this is the real source of the problem??

Okay, looks like the same problem as #104

ubuntu@ubuntu:~/Projects/cariboulite/driver/build$ strings smi_stream_dev.ko | grep vermagic=
vermagic=5.15.0-1037-raspi SMP preempt mod_unload modversions aarch64

ubuntu@ubuntu:~/Projects/cariboulite/driver/build$ uname -a
Linux ubuntu 5.15.0-1043-raspi #46-Ubuntu SMP PREEMPT Mon Nov 13 15:08:58 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux

Now to figure out how to rebuild smi_stream_dev to the latest kernel version and try to understand why that did not happen when I ran the install script this morning.

Update: Following the instructions here https://github.com/cariboulabs/cariboulite/tree/main/docs/smi for rebuilding the driver (note the cmake command is wrong and should be cmake ../../)

I then re-ran the install script and rebooted, and everything works properly.
