Dear ADI Team,

We have designed a custom ZYNQ board with the AD9361. The board has been successfully tested with version 2022.2 and NO-OS, and everything works as expected.

However, while testing with PetaLinux 2022.2, we encountered an "RX Tuning Failed" error during boot. For your reference, we are attaching the device tree and boot log.

Upon comparison of the HDL registers between the NO-OS and PetaLinux implementations, we noticed one key difference in the REG_CLK_FREQ register:

Value in NO-OS: 0x13A93
Value in PetaLinux: 0x27525
The clock source in both designs is 26 MHz, and we have confirmed that the clock at the XTAL is identical.

I have attached the boot logs and dts files in the zip.

Could you please help us identify the root cause of this issue?

Hi,

If it works with no-OS, my guess is that the configuration is done wrongly in Petalinux, regarding the clock rates. I'm guessing this because the clock frequency reported in Petalinux is double the one from no-OS (with a minor error, as 0x13A93 * 2 is 0x27526). It could be that in Petalinux the configuration between the AD9361 chip and the crystal is not ok. So you should probably start with those.

After looking briefly at you dts/dtsi, I see you changed the addresses for the ad9361 and dds nodes. Why is that? They should correspond to the ones in the HDL project. Unless you have a custom HDL project?

Best regards,
Iulia

Hi,

For Clock, we are using the 26MHz Osc of part number "KT2520F26000ACW18TAN" which is fixed and there is no configuration required for the XO as it runs by default from the power on. Yes, as you said, we also suspect the clock configuration only, but in the device tree i mentioned as 26MHZ as input clock. We don't know what else we need to configure in the petalinux.

For the address, we just re-instantiated the ad9361 IP, hence there is a change in the address. The same design we tested with non os.

Please let us know what other aspects we can debug. Also similar to the non os can we enable any debug prints in petalinux for ad9361 drivers?

Hi , could you give some thoughts on the Petalinux side?

Thanks,

Hi,

Could you share the devicetree you have on your system? Also if this is a custom board, how are you integrating it with petalinux? Do you have your own devicetree?

Another thing that could make sense to test would be to manually build things and test it so that we can see if the problem is with the petalinux flow or some other root cause. Manually build instructions can be found here:

Hi,

Thanks for the reply.

We are working on custom board, but we tested the board with baremetal code in vitis, with that we are not getting any rx-tuning error

I'm attaching the device tree of petalinux below.

Hi Team,
could you please let us know the update on the query?

I am attaching the debug prints of Vitis and Petalinux along with the device tree.

WE ARE EXPECTING SOME RESPONSE FROM YOUR TEAM.
