Failed to find device: cf-ad9361-A

Hello,

I was trying to use R2020b, fmcomms5 and zc706 board with "Communication Toolbox Support Package for Xilinx Zynq-Based Radio".

At the beginning of the setup, I format the sd card and set the network as Toolbox requested.Then, plug sd in the board,

i'm having following error:

What could be the reason for this error ?

Thanks

[Martin Enderwitz]

Hi,

This error suggests the libiio driver is unable to probe the AD9361 on the FMCOMMS5. This could be due to a bad connection between the FMCOMMS card and the ZC706, a faulty FMCOMMS5 card, a faulty FMC connector on the ZC706, etc.

To try and diagnose the problem further, could you please try the following:

• Remove the FMCOMMS5 card from the ZC706
• Reinsert the FMCOMMS5 card into the ZC706, ensuring it is fully inserted into the mezzanine connector and stable.
• Run the following code in MATLAB:

rx = sdrrx('FMCOMMS5');

info(rx)

• If that still fails, run the following and share the output for more detailed debugging:

sh = matlabshared.internal.remoteshell('192.168.3.2','root','root');

[stat, log] = sh.execute('dmesg')

Answer 1

Hello Martin,

Unfortunately it still fails. Here below the logs that you requested.

>> sh = matlabshared.internal.remoteshell('192.168.3.2','root','root');

[stat, log] = sh.execute('dmesg')

y

stat =

0

log =

'WARNING - POTENTIAL SECURITY BREACH!

The server's host key does not match the one PuTTY has

cached in the registry. This means that either the

server administrator has changed the host key, or you

have actually connected to another computer pretending

to be the server.

The new ssh-ed25519 key fingerprint is:

ssh-ed25519 255 0f:07:ff:bf:fa:80:61:bc:44:ac:fb:b4:1f:31:1e:4f

If you were expecting this change and trust the new key,

enter "y" to update PuTTY's cache and continue connecting.

If you want to carry on connecting but without updating

the cache, enter "n".

If you want to abandon the connection completely, press

Return to cancel. Pressing Return is the ONLY guaranteed

safe choice.

Update cached key? (y/n, Return cancels connection) [ 0.000000] Booting Linux on physical CPU 0x0

Thanks for help.

Thanks for providing the dmesg output.

Of note are the occurrences of messages such as this:

 [   18.744243] SAMPL CLK: 1000000 tuning: RX
 [   18.748241]   0:1:2:3:4:5:6:7:8:9:a:b:c:d:e:f:
 [   18.752628] 0:# # # # # # # # # # # # # # # #

 [   18.761491] ad9361 spi32766.1: ad9361_dig_tune_delay: Tuning RX FAILED!
 

These messages indicate failures tuning the Tx/Rx front-end filters of one (or both) of the AD9361s on the FMCOMMS5. These failures are occurring at multiple different clock rates (1MHz, 30.72MHz, 61.44MHz), which suggests it may not related to the FPGA timing.

I have been unable to reproduce this issue with any of our own FMCOMMS5 hardware and the R2020b version of this support package. I would recommend the following:

• Reformat your SD card and rerun the setup wizard from the beginning. If you still see the same failures then;
• Reach out via the Analog Devices EngineerZone community forums for additional support in identifying the root cause of your issue, which may be related to this specific hardware.

Hi Martin,

As i understood, ZC706 board may have trouble. I'm going to try renew the ZC706 board and try it again.

Thanks for support.
