My setup:

My issue: sdrpp doesn't receive signals. A quick search found that SoapySDRUtil also shows errors. Please see "shm_open: No such file or directory" and following errors below:

Any help with either issue will be greatly appreciated.

I ran install.sh again (on a fresh DragonOS). This time I noticed earlier errors:

ubuntu@ubuntu:~/projects/cariboulite$ ./install.sh > install.txt

Is this the easiest thing to do to start from Raspberry Pi OS rather than from DragonOS?

Ok first things first get a bigger sd card lol. 16gb is nothing with updates and such. I'd do 64gb min

I have a writeup at https://radiomenace.com/2023/03/20/getting-cariboulite-working-in-dragonos-on-a-raspberry-pi/ but you still need to edit the THIS_MODULE thing.

This is what your config.txt should look like. 

[all]
# Enable the audio output, I2C and SPI interfaces on the GPIO header. As these
# parameters related to the base device-tree they must appear *before* any
# other dtoverlay= specification
dtparam=audio=on
dtparam=i2c_arm=off
dtparam=spi=off
dtparam=i2c_vc=on
dtoverlay=spi1-3cs

I would get rid of all that entire section and try this. if this works then add back one by one to see what breaks it.

next do

sudo usermod -a -G root,dialout ubuntu

Edit /etc/rc.local and directly above the ‘exit 0’ line, insert a new line with this: chmod g+rw /dev/gpiomem

then reboot with

sudo reboot

You can run chmod g+rw /dev/gpiomem in a terminal and rerun your software and it should work as you are getting

[INFO] SoapyCaribouliteSession, sessionCount: 0 Opening rpi in /dev/gpiomem: Permission denied

You will need to edit rc.local as per above because it resets the permissions on gpiomem on boot for some reason.

Hope this helps let me know.

ajkoren1959 commented 5 months ago

Thanks for the advice, ImDroided.

Bigger SD Card: Right on! :-) config.txt file: That's my file too. I'm back to using DragonOS. Raspberry Pi OS requires installation of SoapySDR which comes with Dragon, but otherwise, since I got errors the move didn't help.

I implemented your other tips:

  1. sudo usermod -a -G root,dialout ubuntu

  2. Edit /etc/rc.local and directly above the ‘exit 0’ line, insert a new line with this: chmod g+rw /dev/gpiomem

After reboot, I got: `ubuntu@ubuntu:~/projects/cariboulite$ sudo SoapySDRUtil --find ######################################################

I see in your write-up that you used RPi 3, not 4. Is there a compatibility issue with RPi 4?

ImDroided commented 5 months ago

looks like your stuck where I am now. I have a 4 I dont know where I put I had a 3. check @unixpunk responce and see if that helps. https://github.com/cariboulabs/cariboulite/issues/185

ajkoren1959 commented 5 months ago

@ImDroided, In your writeup you say it's a RPi 3. Your pic of the RPi also matches a 3, not a 4, in my opinion.

Ah yes I remember that now lol the 3 wasn't fast enough and got switched for a 4 almost instantly. I did a fresh install following my writeup and editing the smi stream file the line of code has moved down a few lines as someone added to the file but didnt fix that. I can run CubicSDR but gqrx still has mem access error

ajkoren1959 commented 4 months ago

I have a partial solution. It turns out that the solution to this:

shm_open: No such file or directory
[ERROR] sdrplay_api_Open() Error: sdrplay_api_Fail

is to run the corresponding service: sudo systemctl start sdrplay

Who knew? ;-) Now, sudo SoapySDRUtil --find doesn't return errors,. Also, sudo sdrpp seems to work. However, it doesn't receive any real stations., only static noise at the selected carrier frequency. I run it (and listen) at 98-102 MHz, where I should see multiple FM radio stations...

I'll document a bit more, for the benefit of anyone else who might have the same issues:

ajkoren1959 commented 4 months ago

I'll answer my own question again:
