AD9361 is showing on initialisation TX tuning failed, how to solve this problem, is this a hardware or a software problem
Has your problem been solved?I also encountered a similar problem.My hardware platform is KC705+FMCOMMS3. The bit file I use is kc705_fmcomms2-3_2015_r2. Is your hardware platform the same as mine?
Refer below links
AD9361 FMCOMMS3: TX tuning failed
ad9361_dig_tune: Tuning TX FAILED! ad9361_init : AD9361 initialization error
Moving to No-OS for more inputs.
Thank you for your reply.
I follow the steps of the AD-FMCOMMS2-EBZ Microblaze Quick Start Guide(AD-FMCOMMS2-EBZ Microblaze Quick Start Guide [Analog Devices Wiki] ).Download kc705_fmcomms2-3_2015_r2 from here.
Then I use vivado TCL Shell loading the design.When it is done, I open the IIO Oscilloscope and input IP address on the KC705.But I can't find cf-ad9361-lpc on IIO Devices.
And there is another problem.I use the IIO software to set up to emit a single tone signal, but on the oscilloscope can only see a signal with very short duration, after which no output can be seen on the oscilloscope.
Is the AD9361 unable to output continuously? Or am I using IIO in a wrong way?
By the way,I have used IIO software to transmit persistent waveforms. However, the KC705 used at that time was broken. Now it has changed a new KC705. Is the KC705 I use now broken?But I tested the KC705 with the test method provided by xilinx, everything is normal.
Looking forward to your reply
I have two FMCOMMS3 card. None can find cf-ad9361-lpc in IIO Oscilloscope.But cf-ad9361-lpc can be found on the KC705 board I used before.Is this due to a change in my KC705 development board? Or is it due to another reason? I entered the Linux boot log and saw Tuning TX failed and cf_axi_adc:probe of 79020000.cf-ad9361-lpc failed with error -5.Just like the picture I showed.
This was discussed here: Followed AD-FMCOMMS2-EBZ(AD9361) Microblaze Quick Start Guide Failed too.
