Configuring

When using this card on the PicoZed SDR SOM Development Kit, a slightly different device tree must be used (zynq-picozed-sdr2-fmc-rfcard-tdd). Please see here for further details: Preparing the Image

Function	File
FMCOMMS2/3 Device Tree	arch/arm/boot/dts/zynq-picozed-sdr2-fmc-rfcard-tdd.dts
ZYNQ ADRV9361 z7035 FMC RFCARD TDD Device Tree	arch/arm/boot/dts/zynq-adrv9361-z7035-fmc-rfcard-tdd.dts

This device tree includes the devicetree for the PicoZed SDR SOM Development Kit but configures the AD9361:

• For TDD mode.

• Sets TX LO frequency to RX LO frequency.

• Enables AD9361 GPO2 and GPO3 to slave the ENSM RX & TX states.

• Enables AD9361 GPO0 and GPO1 to control the external LNAs for RX1 & RX2.

• Configures LNA gain and bypass loss.
