cariboulite_radio.c:1048 SMI reading operation failed

[saarbastler]

Hi all,

I have issues to get my Cariboue lite running. If I run the cariboulite_util : sudo ./cariboulite_util -c 1 -f 90600000 -n 100 -

I tested on a Raspberry PI 3B, 3B+ and 4B using Bullseye 64Bit 2023-05-03 and setup as described (git clone, install.sh)

Same result on all my tests.

Please advise how to get it running.

can you make a photo of the modem on board? its on the back side under the "MODEM" label. Edited: Okay it seems like a bug that was already been resolved and overwritten. please confirm that it happens only when running the "self-test" in the test app and that the software runs otherwise.

Thanks, David

Hi David,

here the photo.

the self-test only work once, then it does not find AT86RF215.

The cariboulite_util has this error: 948 E CARIBOULITE Radio cariboulite_radio_read_samples@cariboulite_radio.c:1048 SMI reading operation failed

SDR++ seems to work, but I could not receive anything. I ordered an antenna, I have to wait until it will be delivered.

Thanks a lot, Jörg

I also get SMI reading failed with SDRPP or self test

Gettin the same error. Rpi 4B Image: 2023-05-03-raspios-bullseye-arm64 Clean install as shown in README

mkdir ~/projects cd ~/projects git clone https://github.com/cariboulabs/cariboulite cd cariboulite After that, reboot.

I tried alredy, DragonOS, Ubuntu, Raspbian lite, RPI3 in all possible combinations. The result always ends with a SMI timout.

I tried starting sudo SoapySDRServer --bind, which started without any problems. Then checking with gqrx or sdr++ the stream. After a few seconds I got some samples, but no signal in it. Just a random noise floor with a fat spike in the middle.

Running caribout_test_app and receiving some samples seems so work, but only on the second run. The first run brings again some timeouts...

What can I do more at this point ?
