Hi Jonathon,
Thanks, you are right.
I am normally working with UHD 4.0 on both host and device.
But I forgot I had swapped the sd-card with a uhd 3.15 version for a
test the previous day.
I put the UHD 4.0 back in and now it works.
Best regards,
Martin

Hi Martin,
From your logs, it looks like the E310 locally is running UHD 3.15, but
your host computer is running UHD 4.0. You need to run the same version
of UHD on both the host and device. You should image your SD card to UHD
4.0 using this file:
https://files.ettus.com/binaries/cache/e3xx/meta-ettus-v4.0.0.0/e3xx_e310_sg1_sdimg_default-v4.0.0.0.zip

Hi,
I am trying to run the RFNoC example rfnoc_rx_to_file on a E310 sg1.
When I run it directly on the E310 hardware it succeeds.
But if I run it from a host-computer (connected to the E310 over
ethernet) it fails with:
Error: rpc::timeout: Timeout of 2000ms while calling RPC function
'set_device_id'
The only place I found that does set_device_id is in
host/lib/usrp/mpmd/mpmd_mb_iface.cpp
mpmd_mboard_impl::mpmd_mb_iface::mpmd_mb_iface(
const uhd::device_addr_t& mb_args, uhd::rpc_client::sptr rpc)
: _mb_args(mb_args), _rpc(rpc),
_link_if_mgr(xport::mpmd_link_if_mgr::make(mb_args))
{
_remote_device_id = allocate_device_id();
UHD_LOG_TRACE("MPMD::MB_IFACE", "Assigning device_id " <<
_remote_device_id);
_rpc->notify_with_token("set_device_id", _remote_device_id);
}
But I am not sure what this code does, or why it is run and fails here.
Here is the output of the failing remote and succeeding local runs:
