Failed to satisfy device dependencies for component - Waveform loading on Taget board

[NayanaAnand]

Hi,

I have the meta-redhawk-sdr(Branch : Pyro) with Yocto BSP am57xx and loaded image on Target board.

Loaded image has all the Redhawk components and basic Waveform. Now trying to launch one of the available basic waveform from the image loaded on Taget board(Phytec).

Procedure or Fallowed steps:

1. Target board connected to Desktop server via serial cable and VLAN also available.
2. Started Domain and Device manager with naming services on Target board.
3. Connected to sandbox from python script as shown below :

[redhawk@2a23bdd8bb78 ~]$ python Python 2.6.6 (r266:84292, Aug 18 2016, 15:13:37) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

from ossie.utils import redhawk,sb

import time

dom = redhawk.attach("REDHAWK_DEV")

app = createApplication("/waveforms/rh/basic_components_demo/basic_components_demo.sad.xml") Traceback (most recent call last):

File "", line 1, in NameError: name 'createApplication' is not defined

app = dom.createApplication("/waveforms/rh/basic_components_demo/basic_components_demo.sad.xml") Traceback (most recent call last):

File "", line 1, in File "/usr/local/redhawk/core/lib/python/ossie/utils/redhawk/core.py", line 1794, in createApplication app = app_factory.create(name, initConfiguration, []) File "/usr/local/redhawk/core/lib/python/ossie/cf/cf_idl.py", line 2026, in create return _omnipy.invoke(self, "create", _0_CF.ApplicationFactory._d_create, args)

ossie.cf.CF.CreateApplicationError: CF.ApplicationFactory.CreateApplicationError(errorNumber=CF_ENOSPC, msg="Failed to satisfy device dependencies for component: 'rh.SigGen' with component id: 'SigGen_sine:rh.basic_components_demo_339_120418450_1'")

Understanding from source:

• As seen in the source or *.spd.xml file, observed PROCESSOR name is playing major role with respect to Target boards(cross compiled OS).

• My requirement for Target board is MACHINE_NAME=am57xx-phycore-rdk and PROCESSOR=armv7l

• I have mentioned both variables in conf/local.conf.

• But few of the components only showing armv7l implementation like dsp, rbdsdecoder , device and domain manager spd.xml files.

• All other components are with armv7ahf-neon processor implementation.

Can any one suggest how to change processor name from armv7ahf-neon to armv7l during the building image

If my observations are wrong as per above Error: can you suggest the solution for Failed to satisfy device dependencies for component

Hi,

Please find attachment for the reference (Target board terminal).

This group is not responsible for maintaining meta-redhawk-sdr. Please feel free to submit this issue to our issues list.

That said, the pyro branch uses a much older attempt at patching a processor name into place at build-time by setting the REDHAWK_PROCESSOR value at the global level (a .conf file) as indicated in the README.md. This method was later abandoned in favor of a script relying on redhawk-codegen-native to dynamically patch the XML files to match the various other patches that have to be applied to the core framework source code so that the build-time and run-time environments are guaranteed to match (especially on devices where this value is read from the CPU's registers rather than from source files).

Hi Thomas Goodwin,

Okay, i will post the same question on meta-redhawk-sdr group.
