RedHawk v2.1 Device IDL Error

We have using RedHawk v2.1 on Xynq7035 ARM COretex A9 with Embedded Linux kernel 3.14. Our application is SSB Tx/Rx SDR. So waveforms consist of 3 types, one is SSB RX, two is SSB TX, three is CW TX. The HW device has 6 dataFloat ports and 6 dataUlong ports, each with a total of 12 ports. Start up procedure is below.

#nodeBooter -D &
#nodeBooter -d /usr/lib/redhawk/sdr/dev/nodes/dev_trx_node/DeviceManager.dcd.xml &
#rh_start.py &

rh_start.py code is below.

from ossie.utils import redhawk
import logging
logging.basicConfig()
domain_list = redhawk.scan()
dom = redhawk.attach(domain_list[0])
wave0 = dom.createApplication("/waveforms/rx_waveform/rx_waveform.sad.xml")
dom.devices[1].connect(wave0.comps[0], usesPortName='out_data_rx', providesPortName='in_data' )

The error is occered when connecting the device and waveform port. Error code is

The error is on all the ports of my device and all ports of GPP. My device is created with RedHawk-IDE v2.1. GPP downloads v2.1 and cross-compiles. GPP.scd.xml has no changed. Is the scd.xml file wrong? our device ports section in scd.xml file is below.

<ports>
  <provides repid="IDL:BULKIO/dataFloat:1.0" providesname="in_data_cw">
    <porttype type="data"/>
  </provides>
  <uses repid="IDL:BULKIO/dataFloat:1.0" usesname="out_data_cw">

  </provides>
  <uses repid="IDL:BULKIO/dataUlong:1.0" usesname="out_cnt_tx">

  </uses>
</ports>

The application itself works, but could you tell us the cause of the error and the workaround?

Solution

it seems IDL:BULKIO/dataFloat:1.0 is not present in the IDL library according to the line 1266 of model module init. Check if IDL library exists in the path: $OSSIEHOME/share/idl. also check if your scd file has something like:

<interface name="ProvidesPortStatisticsProvider" repid="IDL:BULKIO/ProvidesPortStatisticsProvider:1.0"/>
    <interface name="updateSRI" repid="IDL:BULKIO/updateSRI:1.0"/>
    <interface name="dataFloat" repid="IDL:BULKIO/dataFloat:1.0">
      <inheritsinterface repid="IDL:BULKIO/ProvidesPortStatisticsProvider:1.0"/>
      <inheritsinterface repid="IDL:BULKIO/updateSRI:1.0"/>
    </interface>

inside the interfaces tag.

a tip: ports can use core-framework IDLs, besides IDL:BULKIO, you can use IDL:CF/Resource to control a component, IDL:CF/Device to control a Device. you are even able to get a reference of the Domain using ports. This way, you can create a single waveform for the SSB (TX and RX) implemeting a proper Assembly controller, to dictate the way your waveform works.

Are you using a ADRV9361 (picozed sdr)? if so... you could evaluate my FrontEnd Device AD936X_LIBIIO... how did you embed (cross compiled) in Zynq REDHAWK?
