Raspberry Pi 3 issue with SPI

[User25514]

I want to use the cariboulite with python, but when I started the ./install.sh
This started coming up during the install:
[INFO] SoapyCaribouliteSession, sessionCount: 0 02-09 02:59:51.999 1617 1617 E IO_UTILS_SPI io_utils_spi_add_chip@io_utils_spi.c:434 spi_init function failed with code -1, (SPI_ERR_OPEN) 02-09 02:59:52.001 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.001 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.001 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.001 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.001 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.042 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.042 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.042 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.042 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.042 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.084 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.084 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.084 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.084 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.084 1617 1617 W IO_UTILS_SPI io_utils_spi_transmit@io_utils_spi.c:606 generic function transfer not implemented 02-09 02:59:52.128 1617 1617 I CARIBOU_PROG caribou_prog_configure_from_buffer@caribou_prog.c:260 Sending bitstream of size 32220 02-09 02:59:55.678 1617 1617 I CARIBOU_PROG caribou_prog_configure_from_buffer@caribou_prog.c:292 FPGA programming - Success!

and then it continues with this:

But it ends and says that all went well.

When I run dmesg | grep spi I get:

And when i run lsmod | grep spi I get:

When I use my python file to transmit, i get:

And whenever I try to execute it in python, I get the error:

The memory access error is a known issue and I have no idea whats causing it see my issue #185

I dont know what OS you are using but you can head to my site https://radiomenace.com/2023/03/20/getting-cariboulite-working-in-dragonos-on-a-raspberry-pi/ and follow what I did some apps work some are mem access errors. CubicSDR works with both S1G and HiF but gqrx is a instant crash

I've realised the issue, so the cariboulite was finicky but the memory issue is only soapysdr's issue. Which means I will be spending the next couple days trying to find a fix.
I tested cariboulite by transmitting on a licence-exempt freq by just starting up ./cariboulite/build/cariboulite_test_app.

God speed my friend... God speed.

I wonder if updating to the latest Soapy would have any effect.

I wouldn't say so, but I have just found that you can automate the soapy sdr install with cariboulite. I haven't tried this yet as I just git clone the soapysdr library. If my python scripts work then I'll report back everything I did

[User25514]

I got it working!
I found that the tutorial I followed using https://github.com/cariboulabs/cariboulite/blob/main/installation.md#installation-details was partly wrong. Instead of installing soapysdr manually, you can automatically download and build soapy when running ./install in the cariboulite folder.
But before that, i made sure to put this in my boot/config.txt file.

Ok glad you got it. A lot of us are running DragonOS which has SoapySDR already installed so the install script skips it but looking at the github code hasn't been touched in long time and DrsagonOS is current anyways.

Personally, if your having issues with soapysdr working with cariboulite, then I would uninstall it on dragon os and reinstall it with cariboulite
