Ethernet works intermittently

Hi

More information: For this purpose I use software code  AD9371/AD9375 API Source Code Ver. 3566

Communication is OK for ZC706 if I don't use this code,The disconnection of communication reads even when I don't run the GUI.

Can you check if the physical ethernet cable connection is proper, without any loose connection ?

Are you able to connect to the board via the serial port?

When you notice communication is lost with the board, are you also unable to access the board through the serial connection?"

Can you try continuously pinging  to the board? Can you check if the firewall is disabled?

Are we connecting the board with a lab network ?

Have we tried connecting the board directly to the laptop/PC directly and check if we do not see this issue?

As we are facing issue since even before connecting to the GUI, this seems to be a network issue.

Can you please try reflashing the SD card image from the below link and check again.

Hi

I did all your questions and still the communication is disconnected.

I have some information that might help you find the problem:

1. Software version I work with the communication works continuously- 2024-11-08-ADI-Kuiper-full

2.Software version I work with the communication don't works continuously- AD9371 Image 20161130

I would appreciate an answer as soon as possible.

Hi 

Thanks for the answer

Are we connecting the board with a lab network ? I didn't quite understand.

Have we tried connecting the board directly to the laptop/PC directly and check if we do not see this issue? Yes I am connected directly I also tried with a laptop and PC, I set the IP address I believe I set it correctly because otherwise I would not be connected.

Can you please try reflashing the SD card image from the below link and check again. I've tried reflashing the sd and working with it several times. 

Are there any other ideas to solve the problem?

Can you please share us the serial port console log with us ?

And once you get the console via serial port , can you check the IP address set using vi/etc/network/interfaces ?

And from the TES GUI and command prompt screenshot shared the IP domain series for AD9375  is 192.168.1.x and not 192.168.2.x.

Below is the IP address screenshot for reference.

Can you please go through TRANSCEIVER EVALUATION SOFTWARE section from the UG-992  for more details.

Hi

And from the TES GUI and command prompt screenshot shared the IP domain series for AD9375  is 192.168.1.x and not 192.168.2.x.  -  I also tried to work with IP 192.168.1.10 without success.

Can you please share us the serial port console log with us ?

I notice that I am booting with an SD CARD (I don't see the default IP setting for the software that needs to be loaded from the SDCARD when the ZC706 is turned on)

I type the ifconfig command and get the following output:

I would appreciate an answer as soon as possible.

Hi

Do you have an answer for me?

There are two GUI options and 2 SD cards for the AD9375. 

• One for Linux driver and IIO Scope (AD-FMC-SDCARD)
• One for Windows-based GUI (ADRV9371-SDCARD)

The 20xx_R1 SD card will work only with IIO oscilloscope based GUI and not with TES GUI. From the serial console log , looks like you are using IIO based SD card,

When you wrote the SD card from where did you download the image. TES SD card image is available here. (ADRV9371-SDCARD)  https://www.analog.com/en/license/licensing-agreement/transceiver-evaluation-software.html

From your first post , looks like you are able to program the board, but you are loosing connection intermittently. I guess you did ping the IP from command prompt and the ping is continuous, If this is the case you need to check if there is some firewall settings that is blocking the GUI communication, 

I am working with the same SDCARD and the same software on 2 different ZC706 cards. One of them has communication working, the other card has communication problem.
Works with Windows operating system and the firewall settings that is blocking.

Which SD card are you using and which GUI are you using ? 

You have 2 setups with ZC706+ADRV9371 and one of them works and the other one does not. Hope my understanding is correct. Have you tries swapping the SD card to rule out SD card corruption. ? Try putting SD card from working system on non-working ZC706+ADRV9371. 

Hi

I have tried yet without success.

From the screenshot shared the IP address entered is 192.168.2.10 , that is the reason we suspected the IP address conflict.

Assuming that the IP address configured is correct i.e 192.168.1.10, have you configured the ethernet settings (eth1) in the /etc/network/interfaces? I don't see this in the console log shared by you.

Below screenshot is from our setup in the /etc/network/interfaces file for reference.

Are you able to continuously ping to the IP address configured in the board?

After configuring the IP address properly and if we still ping inconsistency then the issue might be due to firewall connection settings which needs to be fixed.
