RedPitaya STEMlab125-14 problem

[oligofrenia]

Hello,
I am an owner of RedPitaya STEMlab 125-14. I am trying to use my device for deep memory signal acquisition. I tried to use example code from the documentary(https://redpitaya.readthedocs.io/en/latest/appsFeatures/examples/DMA/deepMemoryAcq.html). I decided to use the Python code version. When I try to use this code, I have an error "ModuleNotFoundError: No module named 'rp'". Unfortunately, The path "/opt/redpitaya/lib/python/" does not exist on my device. I have "/opt/redpitaya/lib/" path, but "python/" folder does not exist there, so I cant add this to my .bashrc file(https://redpitaya.readthedocs.io/en/latest/appsFeatures/remoteControl/API_scripts.html#running-python-applications). What should I do next? Is there any possibility of downloading this library from your repository (I don't see this in the RedPitaya project on GitHub)?

Hello. The documentation corresponds to the latest version of the release. We do not support documentation for older versions.
All updates are downloaded here.

Can I use OS 2.0 version on my device? I am not sure if that device is not too old.

[b-swat]

We have full support for older devices starting from 125-10. At least we test on all devices)))

Thanks for your support. I downloaded a *.img file with OS 2.0 and flashed my SD card. I ran data acquisition, and everything was fine, but after I turned it off, and tried to turn it on again, my device did not work. I reflashed my SD card, but I still can't connect with rp-xxxxx.local address

Hey,
Since you updated from 1.04 Red Pitaya to 2.00, please check #250. That is one potential reason for Red Pitaya not booting properly. Please also try using the recommended Balena Etcher application to perform the flash. If none of the above work, please try establishing a console connection to Red Pitaya, then try using the local address (you can also try pinging the .local address) - https://redpitaya.readthedocs.io/en/latest/developerGuide/software/console/console/console.html#setting-up-the-serial-console

Hey,
I loaded 1.04-28 ecosystem and I found that my hw_rev is correct: hw_rev=STEM_125-14_v1.0. After that, I tried to connect by serial port by PuTTY, and I had access to my device. It looks like SSH and web-based view not working and something is wrong with the network tools.
Best regards,
Oliwia

check on another SD card

I checked and I have exactly the same situation. OS 1.04 work and 2.0 does not

It's hard to say that. you need to look at the systemd log. but looks like a certificate creation problem. Does RP have internet access?

[oligofrenia]

I am working now only with LAN connection without internet access.

[b-swat]

Try connecting to the Internet to create an SSL certificate, after which you can work on the Internet without it.

Ok, It was problem with ssh key, everything fine now. :)
