Kernel boot failure when adding a new/custom devicetree with petalinux

Category: Software
Product Number: AD9136—FMC—EBZ
Software Version: 2021.2

Sorry, I'm very new to linux.

I am configuring AD9136_FMC_EBZ. The HDL design used is 2021_R2 of ZC706.

Because the project support of AD9136 has not been added in the official linux, but only AD9172.

So I add new device tree according to https://github.com/analogdevicesinc/meta-adi/blob/master/meta-adi-xilinx/README.md web page

I use petalinux to create projects.

But in the end, the SD card booted and reported an error.

I did not make any changes to the generated HDL project, only modified the necessary settings to make the DAC AD9136.

The serial port printout of linux startup is as follows:

  • Hi,

    Can you share your devicetree and what have you exactly done to add it? All these errors might indicate some devicetree issue and it's hard to identify the issue with the bootlog.

    Also, if you only have to change some properties on the ad9136, you might just need to extend the base dts instead of adding a new one.

    - Nuno Sá 

  • Hi Nuno,

    Thank you for your previous response. I apologize for my delayed reply as I was busy writing an article and couldn’t make it to the lab earlier. When I connected the 1.4 GHz clock to AD9516, I encountered some issues with the output waveform. Initially, I tried to control it using the ADI IIO OSC software and set the frequency and other parameters in the DAC DATA MANAGER tab, but no waveform was generated. As I am not familiar with the driver framework, I am not sure how to troubleshoot this issue. I have read some documentation, but it didn’t help.

    https://wiki.analog.com/resources/tools-software/linux-drivers/iio-dds/axi-dac-dds-hdl

    I also checked the jesd_status in the terminal, and it seems to be normal.

    Can you please guide me on how to resolve this issue? I suspect that I might have missed some steps in my testing process. Also, I am not sure how to change the sampling rate, input clock size, and JESD204B link parameters. Does this require changing the device tree?Can you please advise?

    Thank you.

  • Hi,

    Sorry for the delay on this thread.

    Nuno is out for a few days. I would need to replicate the issue myself.

    I'm pretty sure it's related to TXEN when you don't see a DAC output, while the link is in DATA.

    We'll get back to you soon.

    -Michael

  • Hi,

    Thank you for your reply. I appreciate your response, and there's no need to rush.

    I want to mention that I have successfully controlled the AD9136 using the Xilinx JESD204B IP core with pure FPGA resources and Verilog language. In my design, I directly assigned txen as 2'b11. It worked but the hardware module implementation was quite rudimentary.

    However, when it comes to the Linux driver, I'm not very familiar with it. If there are any specific instructions or considerations related to the Linux driver that I should be aware of, please let me know.

    Once again, I appreciate your assistance, and I look forward to hearing from you soon.

  • There is one more point I need to add, I have posted it in another post.    Trouble with cf_axi_dds module and modifying JESD204B link parameters   

    I noticed that in the tutorial, the normal startup message for DDS should look like this: cf_axi_dds 79024000.cf-ad9361-dds-core-lpc: Analog Devices CF_AXI_DDS_DDS maste r (8.00.b) at 0x79024000 mapped to 0xf0998000, probed DDS AD9361

    But in my case, it appears as follows: cf_axi_dds 44a04000.jesd204-transport-layer: Analog Devices CF_AXI_DDS_DDS maste r (9.01.b) at 0x44A04000 mapped to 0x(ptrval), probed DDS (null)

    Therefore, I believe this discrepancy might be the cause of the issue.

  • Can you try this change. The GPIO assignments are wrong that's why the TXEN pins are floating.

  • Thank you for your response. Unfortunately, I am unable to perform the testing at the moment. I will conduct the tests in the next couple of days and inform you of the results before the end of this week. I greatly appreciate your assistance and patience. Thank you once again for your support.

  • Hi,

    Thank you for your prompt response and assistance. I greatly appreciate it.

    I wanted to inform you that I have tried the modifications you suggested in the two lines of code, and now I can see waveforms on both channels. However, I'm experiencing periodic loss of synchronization in the JESD status, specifically from DATA to ILAS. This instability in the JESD synchronization results in highly unstable waveforms.

    Additionally, I wanted to confirm the clock signal requirements for the AD9516. Is it correct that the input clock signal should be 1400MHz? I haven't made any other modifications in this regard.

    Once again, thank you for your support, and I look forward to your guidance.

  • The link is rock solid on my side and the spectrum is clean.

    I'm also using 1.4GHz for testing. What is your signal level? Can you use +3dbm ?

    -Michael

  • I have been using the same settings as before, and it remains stable for a few seconds after power-up, but then periodically loses synchronization. I also tried the previous Verilog program , and its link status was very stable without any synchronization issues. Therefore, I can rule out hardware problems. Currently, I am using uImage and devicetree.dtb files compiled separately from the ADI Linux GitHub repository, without using PetaLinux for compilation.
