ADRV9002 + zcu102 linux and GNU Radio support

When I boot, i get a console to the linux but unable to get linux GUI. The screen is jut black and displays a single underscore character.

Are you connecting over UART or with a keyboard+mouse directly connected with a monitor?

Also, wanted to ask is there a GNU Radio support for ADRV9002? Are there appropriate Sink/Source blocks like for fmcomms?

For now, you need to use the generic IIO Source and Sink blocks. These work fine out of the box with ADRV9002.

Hi Travis,

Thanks for the reply.

I'm using UART with teraterm on PC, and monitor through DisplayPort + mouse and keyboard.

Through Teraterm, on the PC, I'm able to access the console. In addition, if i press Alt+Ctrl+F1 on the keyboard then im able to see the console on the monitor connected though the DisplayPort. However, there is no GUI that runs instead of the console on the monitor. And if i try to manually start the GUI through "startx" commend it executes some commands, then hangs on "Loading Extension GLX". I would like to have the linux GUI in order to use the GNU Radio companion on the Zynq.

I did manage to get the GUI on the ZedBoard, so I assume it is supported through the linux on the SD Card, but for some reason, the GUI on the ZCU102 is not executing properly.

Regarding the second issue with GNU Radio, I was able to communicate with the ADRV9002 through the generic iio sink and source. However, I wasn't able to change the sampling frequency attribute. This is not possible through the linux console as well. And also, in iio-osciloscope this parameter is not editable. What can I do to change the sampling frequency?

ZCU102 has a slightly finicky display output and only is known to were with certain monitors. There is something you can try here: https://wiki.analog.com/resources/eval/user-guides/ad-fmcomms2-ebz/software/linux/zynqmp#displayport_-_no_picture

If this does not function you could either X-Forward or use install VNC on the board.

The majority of the configuration of ADRV9002 is done through profiles. See here: https://wiki.analog.com/resources/tools-software/linux-drivers/iio-transceiver/adrv9002#profiles

Hi Travis,

I've successfully got the GUI after trying the instructions on the link you've attached.

Ragarding the profile. I created a profile and a stream using TES for the adrv9002.

However, i've failed to load them via the iio-osc. It gives me an error "Failed to load profile using the selected file!", tried loading the stream before and same error there.

I've also tried the method through the console, proposed here:

https://wiki.analog.com/resources/tools-software/linux-drivers/iio-transceiver/adrv9002#profiles

however, i'm getting an error that I dont have premission when trying to do the folowing:

root@analog:/sys/bus/iio/devices/iio:device1# cat /media/analog/BOOT/kozlov/prof
ile1.bin > stream_config
-bash: stream_config: Permission denied

If you are using the BOOT.BIN from the 2019_R1 release it only supports TES v0.12.

TES v0.14 is supported in the pre-release SD card here: https://github.com/analogdevicesinc/hdl/releases/tag/hdl_2019_r2
