Hi @zhangtemplar

I Had the same issue, and it turned out to be a mismatch between the running Linux kernel and the installed header files.

Have a try doing apt update && apt upgrade && reboot prior to cloning the git repo and running install.sh and try again :)

thanks @bcshort , let me try

Confirmed /dev/smi exists but when try to open it got this error: 

sudo cat /dev/smi 
cat: /dev/smi: Cannot allocate memory

One thing weird is that with lsmod | grep smi, I got

smi_stream_dev         20480  0
bcm2835_smi            20480  1 smi_stream_dev

instead of

bcm2835_smi_dev     16384   0
bcm2835_smi         20480   1   bcm2835_smi_dev

I initially got the same results as you. smi_stream_dev appears to be what is now expected as of today.
https://github.com/cariboulabs/cariboulite/blob/main/software/libcariboulite/src/caribou_smi/README.md appears out of date. After much problem solving today somewhere along the way I lost one of the smi entries and now only have 

bcm2835_smi         20480   0  bcm2835_smi_dev

pi@raspberrypi:~/projects/cariboulite $ cat /proc/modules

bcm2835_smi 20480 0 - Live 0x0000000000000000

The above is the only smi related line in modules.

I believe this and different kernel lib header file versions (also brought up in #issue #55) are now causing the below errors (with further dependent downstream errors) and perhaps the last things between me and a working system.

The kernel header mismatch (this is part of the cariboulite install.sh script)

This error does not appear to stop the install script which finishes with "All Good, now reboot" messages.

I am on the latest bullseye OS on Pi4B.

In summary I see 4 things:

  1. The kernel header files mismatch I think is still a problem.
  2. The make file error for the above is not caught or corrected.
  3. The https://github.com/cariboulabs/cariboulite/blob/main/software/libcariboulite/src/caribou_smi/README.md is out of date
  4. I lost a module entry and do not know how to fix it (updates/upgrades and reboots have not fixed it)

Looking for how to resolve the above issues.

K7MDL2 commented 1 year ago

Some more clues from dmesg fresh from a reboot. See the last 2 lines about versions. Possibly sorting out the headers mismatch might also fix up the module loading? Will continue to poke around, not my area of expertise. This is on a Pi4B with branch develop_R1.

Focusing on the version issues. I do not know why CMake is coming up with 5.15.84-v8+. Here is the relevent portion of code in /home/pi/projects/cariboulite/software/libcariboulite/src/caribou_smi/kernel/CMakeLists.txt 

# Module info
add_definitions(-D__KERNEL__ -DMODULE)

# Find the kernel release
execute_process(
        COMMAND uname -r
        OUTPUT_VARIABLE KERNEL_RELEASE
        OUTPUT_STRIP_TRAILING_WHITESPACE
)

# Find the headers
find_path(
        KERNELHEADERS_DIR
        include/linux/user.h
        PATHS /usr/src/linux-headers-${KERNEL_RELEASE}
)

message(STATUS "Kernel release: ${KERNEL_RELEASE}")
message(STATUS "Kernel headers: ${KERNELHEADERS_DIR}")

It puts out both the 6.1.19 and 5.15.84 for some reason. My OS is 6.1.19 as seen with uname -r. I edited /home/pi/projects/cariboulite/software/libcariboulite/src/caribou_smi/kernel/build/CMakeCache.txt 

//Path to a file.
KERNELHEADERS_DIR:PATH=/usr/src/linux-headers-6.1.19-v8+

to force the header file path to the current OS version then ran cariboulite/install.sh again. This time I can run the test and SDR apps and the smi module is added without error. I still get SMI read timed out with SoapySDRServer but at least the driver errors are gone.

I now have this result.

pi@raspberrypi:~ $ lsmod | grep smi
smi_stream_dev         20480  0
bcm2835_smi            20480  1 smi_stream_dev

Now to find out why the SMI reads are timing out. Using the caribouLite_test_app I can see data is read from the both channels. below is the SMI read timeout error I always have. This error message below happens to be from SDR++ server mode using SoapySDR. The same SMI timeout error occurs on a direct Soapy connection and SoapySDRServer. RTLSDR works fine over SoapySDR local and remote.

K7MDL2 commented 1 year ago

Progress. I switched from develop_R1 branch to main branch, ran install.sh. The linux header version remained correct, Not sure if it was the old modified file or it worked correctly yet. In any case I rebooted and can now RX on SDR++ over SDR++Server (both on the RPi) network connection. Runing SDR++ client on the RPi4 it is at 100% CPU and the audio is choppy. Running the client on a Windows CPU the PI is at abut 14%. There is a large hump in both clients display but the audio is clear for FM radio band. The HF bands such as 5MHz has pops and low signal level with the display flashing at each pop. It is a big step forward in any case.

Later I tried CubicSDR and some other configs and the SMI timeout returned. Rebooting the Pi and starting up sdrpp --server made it work again, same hump in display but audio not bad, some visual flickering, On a PC, the CaribouLite HiF RX, listening to FM stereo, SDR++ reports around 50-57Mbit/s rate. The Pi is at 12%. The FM stations are visible riding along the hump. The RTLSDR shows a proper spectrum with larger signal amplitudes, same antenna. So it is a bit fragile, but it is now within reach of work right.

This is on the main branch. The SMI kernel driver is significantly changed between main and develop_R1 branches according to posts.

SDRPP on CaribouLite

I found the display and audio popping on the lower bands like 5Mhz AM or 7.074Mhz USB (FT-8) the audio pops and display show up but go away it seems if you turn off the AGC. Raise the Gain high and it pops. So something is funky with the AGC. Data rate is now around 26Mbit/s (compression on).

Increasing the Source (REMOTE) bandwidth to 2MHz, changing to Float32, Decimation at something other than none, and adjusting the modem AGC gain down to around 35 the hump went away, sound is clear, spectrum and waterfall is pretty decent. The FM band hump also diminishes. I am getting mirror images however. Uncompressed the stereo FM stations was 240MBits/s!!. The Pi4B seemed not bothered. Over time while writing these notes the sdr++ client eventually faded out and then completely stopped updating the spectrum and audio, the spectrum width also failed to widen according to the bandwidth settings. Restarting the client solved those problems. Decimation = 4-8 seemed like a good compromise.

SDRPP HF on CaribouLite

Hopefully these notes will help make progress.

I found the issue. I made a mistake between i2c_vc, i2c_arm and i2c. Now it is working properly.

K7MDL2 commented 1 year ago

The original problem with the install.sh messages requiring sudo is fixed if you place sudo in front of cmake on line 117 per below.

printf "${CYAN}3. Main software...${NC}\n"
cd $ROOT_DIR
mkdir build
cd build
sudo cmake $ROOT_DIR/software/libcariboulite/
make
sudo -u root make install
edegraaff commented 1 year ago

should you enable those in the /boot/config.txt or disable them ? the insttall scripts mention to add a line, while the main site advices to disable them ...

zhangtemplar commented 1 year ago

you should only have i2c_vc enabled and the others should be disabled

Mudary commented 1 year ago

Hi, wondering what or whose git version, cariboulite or konimaru are you running. Thanks Mudary

K7MDL2 commented 1 year ago

konimaru fork is working for me. I think the sudo cmake comment above still likely applies.
