AD-DAC-FMC-EBZ with AD9163 bring-up

Hi,

As a starting point you can use the HDL design referenced here.

Together with that you can use the latest Kuiper linux image but unfortunately the devicetree is not included in BOOT partition yet so you'll have to build one on your own using this devicetree source

After that please try to use the IIO OSC tool already built in Kuiper image. With OSC tool you can load a waveform file and it will be streamed from DDR to DAC using the DMA.

Hello, 

Thank you for the reply.

The device tree source you mentioned is socfpga_arria10_socdk_ad9136_fmc_ebz.dts

So is this also covering ad9163? 

and can you suggest me a way to build it? 

Best Regards,

Ömer.

The devicetree I linked is targeted for https://wiki.analog.com/resources/eval/user-guides/ad-dac-fmc-ebz and it should support ad9163.

You can follow the steps presented here: https://wiki.analog.com/resources/tools-software/linux-build/generic/zynq to build the device tree

Thank you, I have used the device tree from your link and followed the steps from here to build the Kernel and the Device tree https://wiki.analog.com/resources/tools-software/linux-build/generic/socfpga

I have built also the FPGA project in Quartus and generated rbf and put all in the SDcard and booted. It seems boot is successful. 

I have also the  EVAL-AD916X board attached to FMCA connector of the A10SoC.

Now how can I verify actually that I have everything in place correctly? Are there some simple check points that you can suggest and any simple application examples to read/write registers and so on.. ?

Best Regards,

Ömer.

for example at the situation now, I don't have any iio devices appearing on the linux system. Is this normal? What should it look like to be said "it is OK to try some application now"

BTW - please don't open multiple threads for the same issue.

Can you please provide your kernel startup messages?

-Michael

Hello.

I opened the other thread since I thought and I saw in other past threads comments that encourage to open seperate tickets once the initial question is answered, and I even thought that not doing so would be a reason to not getting response since the thread is getting longer and longer

Aboiut the issue

I dig into the problem more in the meantime. And I realized that the kernel modules are not present/installed and loaded. in other words usr/lib/$(uname -r) does not exist.

I am trying to find out now: 

1- How can I build the .ko files during the kernel compilation?

2-How can I be sure that the rootfs has all the necessary files (including these modules built in 1-.  but are there any that I need to manually put in or somehow be sure with a script that all is in.)

Below are the full startup messages. Hope not too long.

Update: 

I have managed to  get the relevant directory stucture by 

make modules_install ... command and copy it into the rootfs to the relevant location. 

now the errors about the Load Kernel Modules has gone. 

Still I dont have and spidev or iio devices. 

One thing also I did is I have configured the spidev as an external modules instead of a builtin one and it loads also during the boot now as a module with its own .ko file. 

However at the moment I am looking into udev rules and I cannot see anything that could create relevant nodes either for iio devices or spidev.  

Most probably I will add some rules for those purposes as a next step. 

However it would be really great to have a proved rootfs ready alongside the pre-build Kernel image coming as a packet with the Kuiper SDCard image comes from below:

Kuiper linux image

I will update if I have something more.

Dear mhennerich and btogorean, would it be possible to share the Linux root file system of the evaluation board ADS7-V2EBZ ? At least I could have an idea to look into which drivers should be loaded at boot,  what udev config is needed and so on..  

Otherwise do you have any suggestions to get correct root file system to be able to do the following?: 

On A10soc Board, DAC-FMC board connected via FMCA, run the example application code given in the EVAL916x API for example?  Or as you suggested get something out using IIO_OSC? At the moment I cannot move a single step forward to evaluate the 9163 DAC in this setup, no single byte send to configure any chip on the DAC FMC board, no signal coming out.. 

Best Regards,

Ömer.

I don't think the rootfs of the ADS7-V2EBZ will be any useful. This board is supposed to work with ACE. A closed source evaluation application. And all driver actually run on your Windows PC.

Use our Kuiper image, build all drivers into the kernel, as we typically not use modules.

Use this devicetree as an example:

• https://github.com/analogdevicesinc/linux/blob/2019_R1_altera/arch/arm/boot/dts/socfpga_arria10_socdk_ad9172_fmc.dts/

There are some more AD916x examples here:

• https://github.com/analogdevicesinc/linux/blob/master/arch/arm/boot/dts/adi-fmcomms11.dtsi

Bindings are explained here:
