Hello,
I have a problem that I can't solve despite searching the forum and the guide provided by analog device.
I have the ADRV9364-Z7020, ADRV9361-Z7035, ADRV1CRR-BOB and ADRV1CRR-FMC boards.
I want to connect an external oscillator, so for this I have to use a 26MHz TCXO on the ADRV9361-Z7035 + FMC board through the J1 connector.
When I change the reference oscillator in the devicetree, when I start the board I get the following problem:
RX Tuning FAILED.
And also when I check the clock to use with cat / sys / kernel / debug / clk / clk_summary, I don't see the change I made in the reference clock.
To resolve the first bug I followed what was recommended in the forum and disable the FIR filter and set adi, digital-interface-tune-skip-mode = <0x02>.
This way I no longer get the error in RX Tuning.
1) Can you help me with the setting of the reference speed? Where can the error be?
2) When I make the changes to eliminate the error in RX Tuning Failed. What problems can this bring me?
On the other hand I tried to change the device tree of ADRV9364Z7020 + BOB and I can see the change in the clock setting. But I can't do it by combining ADRV9361-Z7035 + FMC,
I get the same problems that I already detailed.
3) Are there any errors or things that I have to take into account with the ADRV9361-Z7035 board?
Attached is the device tree of AD9361-Z7035 + FMC.

Please I need help,
Thanks.
