Hi

I uploaded this question a while ago but haven't got any response yet.

Please have a look at this and I'd really appreciate your help.

:

I have an AD-FMCDAQ2 Rev. D and a KC705 board.

Following the instruction, AD-FMCDAQ2-EBZ Quick Start Guide(AD-FMCDAQ2-EBZ Quick Start Guide [Analog Devices Wiki]),

the prebuilt image(kc705_fmcdaq2_2014_R2_PRE.zip) was successfully downloaded to KC705, and it shows an ip address in my network.

But the remote iio oscilloscope does not work right (seemingly not all devices on board are identified.The picture below shows the result of connection.)

When I look into the UART log (attached) and compare it with the reference log shown in the above link, my log is different in some lines:

 

sched_clock: 32 bits at 99MHz, resolution 10ns, wraps every 43383508981ns <- as opposed to 100MHz in the reference log.

cf_axi_jesd204b_gt 44a60000.axi-jesd-gt-rx: RX Error: Interface Error

ad9467 spi32766.2: Failed to initialize

ad9467: probe of spi32766.2 failed with error -5

 

Any comment or help would be appreciated.

%FYI, the remote iio fails to connect to the board. The above image was captured after several rebooting.

 

Thanks.
