Picozed SDR breakdown

halimlee — Mon, 14 Oct 2019 15:39:00 GMT

Hi, I'm working on Picozed SDR 2x2 SOM board (I bought a software development kit). I wanted to connect the board to a portable battery and use it, and in the process, the board seems to have overcurrent. After a little noise, the board was turned off, and after that, the board will not turn on.

Is the board completely broken? Or can you tell me how to solve this problem?

Also, if the board is totally broken, do I have to buy all the new parts?

100frk — Thu, 17 Jan 2019 06:52:32 GMT

Dear All

I am working on picozed sdr som (adrv9361-z7035 ) . downloaded the reference design (HDL - linux OS) and then inserted ILA to see the samples on ADC path and DAC path. On ADC path I observed some samples but on DAC the data is zero. kindly help me how to do this loop back (RF RX--->RF TX) .

Regards

Unable to find device: No such device.

Former Member — Tue, 21 Aug 2018 17:28:18 GMT

After compiling the FPGA and using cammand:

"sudo iio_reg cf-ad9361-lpc 0x8xxxxxxx" I get: 'Unable to find device: No such device'

I do not have any timing errors. This seems to happen randomley after a recompile. This seems to be happenning more often and after a recompile this error goes away. Some time it takes several recompiles. Any ideas what to look for?

On the page, http://microzed.org/product/picozed-sdr-development-kit, the video "Day 1 PM Lab: QPSK Receiver with Radio-in-the-loop " cannot be viewed.

Where can one find this video and all other information regarding the Software-Defined Radio with Picozed SDR SpeedWay 2015?

Thank you

HW mac addr

Former Member — Fri, 08 Dec 2017 15:12:58 GMT

Hi, I have spent some time trying to see where the board gets its mac addr from for eth0 and I am now stumped. This is a unique address which is on a sticker on the SOM. I thought perhaps this was programed into the EEPROM, but this is blank. Can anyone tell me where this is actually set?

Thanks

Undeterminated start state

Former Member — Tue, 28 Nov 2017 11:27:28 GMT

Hi, nice to meet you everyone.

Within a University Research Project, I'm working on a PicoZed SDR platform (PicoZed+PicoZed SDR) to implement a full duplex SDR able to communicate with some RFID-like tags.

The communication paradigm is quite simple: the SDR shall modulate an 5.8GHz RF carrier through an ASK modulation scheme (simply putting MIN_DAC,MAX_DAC values on the sample input port), and after that during a MAX_DAC interval belonging to a full continuous wave period such wave will be used by the tag to modulate its data through a switching diode.

The radio works almost all the time.

The problem is that sometimes, at the power-up and after the PLL is locked (that's verified through the AD9364 SPI registers state), the 9364 seems to totally ignore the sample stream which I send synchronous with the DATA_CLK and TX_FRAME signals. Looking through a spectrum analyzer, the PLL seems to be well-locked, but the carrier level is the same as when I put a flow of all zeros as samples: changing samples does not change anything.

When this happens, the radio must be switched off, resetted and restarted to restore the full functionality. This way, the "zero" RF carrier level is the same as in radio-stuck case, while the "one" RF carrier level belongs to the maximal output power.

I'm using Vivado 2017.3.1, and all the timing constraints are met. Also verifying through the oscilloscope, the samples are correctly sent both when the radio started well or not.

Actually I put a workaround making the radio resetting itself until a valid tag answer is obtained, but I would not apply such scheme in the final implemented product.

Have you any idea?

Thanks

No Network Activity on Ethernet

alionneemah — Tue, 29 Aug 2017 18:55:13 GMT

Hello,

I may have a problem with one of my PicoZed SDRs. It seems the Ethernet PHY has an issue. Linux boots the PHY without a problem and can read/write from/to the PHY, but anything external doesn't see any activity. For example, basic network functions such as ping won't work.

We tried multiple carrier cards, and the problem appears to follow the SOM. Using a new SOM fixes the problem.

Thank you for your time.

PicoZed SDR power-only carrier

liuf_stanford — Thu, 06 Jul 2017 21:17:23 GMT

We're developing an application using the PicoZed SDR which needs only power inputs from the carrier - no IO (ethernet, USB, HDMI, etc...) required. Since we don't want to re-invent the wheel, are there any such designs which already implement this functionality? If not, are there any good resources out there which might help us design our own carrier?

I know Avnet no longer sells PicoZed SDR units, but I'm posting here since replies on the EngineerZone forum are slow (and mostly useless).

Thanks!

Power Supply for PicoZed SDR

100spacegeek — Fri, 23 Jun 2017 17:53:20 GMT

I have a board with the model number AES-PZSDRCC-FMC-G that my research group received from another company. However, the company did not send the power supply. We've tried using a computer power supply from a work station (1300 W), but the power supply did not deliver power. Can I please get the specs for the appropriate supply, or a link to purchase one?

No firmware for sdr1 on breakout SD card

gastraea — Thu, 15 Jun 2017 02:34:48 GMT

Apologies if this is not the right place for this issue.

The SD card that came with my Breakout Carrier did not come with the folder zynq-picozed-sdr1-brk. I need this folder as I am using an SDR 1x1.

I have not been able to find out a simple way to just download this folder. I'm wondering if this is related to the change over from avnet to analog devices.

I have browsed Avent and Analog Devies git repos and it looks like there may be a way to recompile these but I'm a noobie and just want a known entity that matches the "Getting Started" instructions. At least then I can branch out from there.

Any pointers would be welcome.

PicoZed SDR 1X1 SOM Documentation

Former Member — Wed, 31 May 2017 11:44:05 GMT

Hi,

Could anyone provide the detailed schematics and relevent documentation for the PicoZed SDR 1x1 SOM produced by AVNET?

They are available for the 2x2 SOM, but not for 1x1 SOM which includes a different Zynq chip, and a different analog chip.

Regards.

PicoZed Peripheral Interfaces

jshimoun1 — Mon, 22 May 2017 20:49:46 GMT

I would like to attach several peripherals using some of the available interfaces on the PicoZed, starting with I2C and SPI. One such peripheral might be a 9DOF accelerometer.

I am currently running the standard Linux image. Is it possible to connect these peripherals without modifying the SD image in Vivado? Is it possible only with Linux drivers?

PicoZed SDR compatibility with ON PYTHON-1300-C Camera Module

jshimoun1 — Mon, 22 May 2017 12:53:53 GMT

I have a Picozed SDR 2x2 and SDR FMC Carrier Card included with the PicoZed SDR Development Kit. I would like to connect the ON Python 1300 Camera Module to the Picozed through the PCI port on the carrier card.

I currently have the standard image booted on the SD card and I would like to use the camera interface through Linux drivers instead of modifying the hardware image. Is this possible? Can I simply modify the device tree to include the Python Camera? Are there drivers that I can download for the camera?

Windriver Pulsar linux image for Picozed-7035 SOM

vinaygb — Tue, 09 May 2017 03:36:49 GMT

Hi,

The picozed 7035 som comes with an SD card pre-installed with windriver pulsar linux.

Where to get the image of this linux for further development ?

It is not available in the repository of windriver - https://distro.windriver.com/public_feeds/WindRiver-Pulsar-Linux-Avnet-PicoZed-image/Releases/Latest/

Latest available is that of picozed 7030.

Is Picozed 7030 similar to Picozed 7035 som?

PicoZed 7035 SOM board definition files

vinaygb — Tue, 02 May 2017 02:30:43 GMT

Its been more than 6 months since the release of Picozed 7035 SOM and we don't see Board definition files for vivado yet.

In one of the forum topics, this issue was discussed and ADI TCL scripts are suggested as solution.

But there are no gudies/manuals for developing using those scripts.

Kindly provide Board definition files for Picozed 7035 SOM or provide user manuals for those scripts.

PicoZed SDR configuration process

banksbh — Fri, 21 Apr 2017 13:45:52 GMT

I have seen examples using Mathworks Simulink, communications toolbox, HDL Coder, and embedded coder.

The examples use the Workflow advisor for channel mapping and setting up the rx and tx paths. Also, the system blocks can be separated into what will be part of the ARM section and what will be part of the FPGA fabric section.

My question is on how this can be accomplished using Mathworks Simulink and the Xilinx Vivado design suite and System generator. I have designed a system using the Xilinx blockset which I can generate the binary data stream. I wasn't sure the process for implementing the ARM section and linking it with the FPGA portion. I have seen some c code examples on setting up the hardware, setting Tx and Rx freqs, BWs, etc. I wasn't sure the exact process. Are there any examples that show how this is done? Also, is there info on configuring the ports for the signaling. I figure this is done with the constraints file, but details on how this is implemented would be greatly appreciated.

Thanks in advance,

Brian

Communication system proto-typing using PicoZed SDR board

vinaygb — Mon, 10 Apr 2017 04:10:54 GMT

Hi,

We are trying to build an end-to-end communication link using PicoZed SDR modules.

End-to-End means sending data from computer over ethernet, receiving it on ARM running Linux and passing data over to FPGA running QPSK modem(the one provided in matlab packages), configuring AD9361 for RF communciation and sending data over air using AD9361 and receiving on another PicoZed module(or loopback) and passing data to another computer.

There are no proper software guides available at one place/website for complete development starting from Data handling on Linux to configuration of AD9361 and communication using example transceiver.

All we can do is run existing QPSK hardware in loop example which sends data from ARM and receives it on Computer(running Matlab).

There is no description of how ARM is linked to FPGA fabric and how to access and configure this interface.

Also how to build custom software on Linux which is provided along with Picozed SDR ?

How to access ADAU1761 for voice communication ? There are many forum questions which discuss ADAU1761 but none explains how to build the configuration code in existing Linux of Picozed SDR.

May be these questions are trivial for expert programmers in Linux. But someone who has worked only on FPGAs might need a little more specific guides on using linux on ARM.

Kindly help in addressing these issues.

MIMO beamforming using PicoZed SDR

ludoferranti — Thu, 06 Apr 2017 20:43:59 GMT

Dear all,

I recently acquired a PicoZed SDR and I intend to use it for MIMO beamforming.

Although I'm experienced with SDRs, PicoZed si pretty new to me, so I wanted to ask for advice.

Is there any design constraint that I should keep in mind while using PicoZed for MIMO beamforming?

Is it possible to implement such scenario directly from MATLAB or I need to get down to lower levels of programming?

Thank you all.
