We tried the loop-back with the provided script, but unfortunately it did not work. It is worth noting that the IPv4 and port used were "192.168.10.10" and "22" (SSH) because our board is a custom-made one (which is connected via ethernet to the PC) instead of an ADI evaluation one. Moreover, the same error was issued upon running the code:

I was wondering if there is a way to set the TRx in internal digital loop-back through the API instead of Iron Python.

I would like to mention that we have tried to use the following functions without success:

• adrv9010.Control.ProductIdGet() -> Error: System.FormatException: Input string was not in a correct format.
• adrv9010.Tx.TxAttenGet() -> Error: System.FormatException: Input string was not in a correct format.
• adrv9010.DataInterface.DeframerStatusGet() -> Error: System.ArgumentException: respString parameter did not have enough comma separated values to correctly parse
• adrv9010.RadioCtrl.RxTxEnableGet() -> Error: System.ArgumentException: respString parameter did not have enough comma separated values to correctly parse

Here is our code: test_ADRV9026conn.py

We are not sure whether these errors are related to the ADRVTRX Eval. Soft. because we got a few errors during the installation:

Please provide the FPGA details used in your setup?

Are you using the ADRV9026 -SDCARD image from here ADRV9029 Datasheet and Product Info | Analog Devices

adrv9010.Hal.SpiByteRead(address, 0) which we are still trying to solve.

Could you please try writing and reading from Scratch pad register 0x00A multiple iterations to check SPI functionality.

No, we are not. Since our board is custom-made (as mentioned in a previous reply), we are using our own SD card featuring Petalinux. It is worth mentioning that we imported all necessary files regading the ADI API into Vitis for building and launching the application.

As long as we use the API, we are able to initialize, configure and monitor the transciever. Therefore, we are pretty sure the SPI is up and running properly.

The very same error was issued when we tried to read the indicated register. A time.sleep(0.5) cmd. was added after both the spiWrite() and spiRead() ones, although they are not shown in the code below. In fact, they were removed because strangely the time.sleep() cmd. was not allowed to be present in the inserted code.

We tend to think these errors suggest that it might not be possible to use Iron Python for completely configure and monitor the transceiver in our specific case.

Can you try running a basic script printing "Hello world" using Iron python in your setup and confirm that the environment is fine?

Upon running the suggested basic script, we concluded the environment was working just fine.

Is there any new update here?

Can you try writing a different register and readback if its successful?

We got the very same errors as before. We continue to be unable to use Iron Python for completely configure and monitor the transceiver in our specific case and custom board.
