I've made it a habit to always be explicit about which device (or device class, at least) I'm going for when I use UHD tools.
So, I *always* either specify "--args type=usrp1" or --args "addr=192.168.10.2" to UHD tools, so that I don't have to rely on autodiscovery stuff that might produce weird results. I kind of *have* to on one of my systems, because I have both a USRP1 and USRP2 on the same system.
I vaguely recall from the mists of my memory that there's some subtle brokenness with SIGINT handling in *BSD Python and Gnu Radio, but that's as much as I remember.
In terms of why it's reloading the .ihx, I'm not sure, although I'll note in the code that there's a "force" parameter to the routine that loads the firmware, so that if "force" is set, the FX2 firmware is reloaded regardless of whether the local-file and on-board hash match. I'll also note that the routine that *calls* the firmware loader doesn't actually supply this parameter, so perhaps there's actually a bug.
Whereas the routine is defined here:
void usrp_load_firmware(std::string filestring, bool force)
I'm not much of a C++ guy (more of a C-only fossil), but it seems like there may be a mis-match in the args here, and that maybe on *BSD it just *happens* that the "force" parameter is being set by accident.
Perhaps Josh (when he's awake :-) ) can comment.
