FMComms2/3 plugin missing

Hi,

I'm trying to make work the AD-FMCOMMS3-EBZ in a custom board with a xc7z015clg485-1 ZYNQ FPGA.

So far i have adapted the Zedboard's project in vivado, taking away the following:HDMI, USB0, SPI1, i2s, spdif, GPIO, and have created the BOOT.bin, also the devicetree and the uImage including the drivers.

The custom board finds the ad9361-phy device under  /sys/bus/iio/devices/iio\:device0. When the ADI IIO Oscilloscope is connected through Ethernet a message ( see below) appears automatically in the board's terminal, also the following plugins appear on the oscilloscope: Debug, DMM and FMComms2/3/4/5 Advanced, but not the FMComms2/3 plugin.

When I connect the oscilloscope to the Zedboard it starts with a preset, and a lot of settings fixed, but at the custom board all the values are empty.

Would anybody know what step am I missing? I would really appreciate any help.


Best regards

Huse
