I fixed a typo and pushed it to the master. When you leave the dboard
name blank, and you have a single slot, it should use the name of the
only daughterboard slot on your usrp. Except for the typo...
So, to use the AB subdev on basic RX on usrp2, the following would work:
"0:AB"
":AB" - was previously broken by the typo
"" - empty string automatically picks the first subdevice 0:AB

Hi Josh and List,
I am now trying to use the latest version of UHD. I am working with one or two
USRP2s (I have previously worked successfully with up to four USPR2s).
I tried the following which I though should be the way to handle a general
number of USRP2s (no_ant).
std::string abcd_string("ABCDEFGHIJKLMNOPQRSTUVXYZ");
uhd::usrp::subdev_spec_t abcd(":"+abcd_string.substr(0,no_ant));
d_mdev->set_rx_subdev_spec(abcd, uhd::usrp::multi_usrp::ALL_MBOARDS);
d_mdev->set_tx_subdev_spec(abcd, uhd::usrp::multi_usrp::ALL_MBOARDS);
However, I get the error:
error: Validate rx subdev spec failed: :AB
assertion failed:
is not a valid rx dboard name.
possible values are: [0].
Then I made a different intepretation and tried:
uhd::usrp::subdev_spec_t e("0");
for (uint32_t i1=0;i1<no_ant;i1++) {
d_mdev->set_rx_subdev_spec(e, i1);
d_mdev->set_tx_subdev_spec(e, i1);
}
However, the results are still in error.
