Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

Recently I received a pair of PackRFs. When I ran with 2016_R1 image, the RFSOM-BOX-GUI showed up immediately.
However, when I ran with 2019_R2 image, the Linux penguin showed first and then the Linux desktop showed up. The screen is so small that I could not find the application tab and run the RFSOM-BOX-GUI, let alone finding the IP address of the PackRF.
Is there a way to start the RFSOM-BOX-GUI by using the click wheel and button only?
Thanks a lot in advance.
I checked the /etc/rc.local file in the 2019_R2 image after typing "sudo adi_update_tools.sh dev" to update the tools. It does have the command "/usr/local/bin/rfsom-box-gui-start.sh" to run RFSOM Box GUI automatically. However, when I run /etc/rc.local, there are some errors.

Here is the screen on the PackRF.
Some stuff changed when we switched to Kuiper Linux. I'm looking into a solution for it and let you know once I figure it out ..

Hi ..
Can you edit /etc/rc.local and remove the line invoking rfsom-box-gui-start.sh .
After this can you try running adi_update_tools.sh as I've updated the scripts and the application.
Thanks,
-Adrian
Can I still use "adi_update_tools.sh dev" instead of adi_update_tools.sh? This is because I still prefer libiio ver 0.23.
I fixed the iio_attr -q here: https://github.com/analogdevicesinc/rfsom-box-gui/commit/d2bf5906deccda3a15a9ec873c13d89dfb29dc88 I think this bug predates libiio v0.23 so you should be able to use libiio v0.23 without issues.
-Adrian
Thank you for your fix, Adrian. I use either "adi_update_tools.sh dev" or "adi_update_tools.sh" and the RFSOM-BOX-GUI comes out.
Hi Adrian,
If I boot the Packrf and don't want open rfsom-box-gui at startup, how should I do?
Thank you very much.
You could ssh into the device and do "killall -9 rfsom-box-gui". Alternatively you could disable packrf permanently by running
sudo systemctl disable packrf.service
The command to enable the systemd service is here: https://github.com/analogdevicesinc/linux_image_ADI-scripts/blob/master/adi_update_tools.sh#L144
