Hey EJ,

Sorry for being slow I had to dig around to set that UHD Log variable,
which easy enough it was just a simple export. I then ran uhd_usrp_probe
with the --tree and setting the fpga to my bit file. Here is the output
from the probe.

root@ettus-e3xx-sg3:~# uhd_usrp_probe --args="fpga=./newinstall/e300.bit"

[INFO] [E300] Loading FPGA image:
/home/root/newinstall/usr/share/uhd/images/usrp_e3xx_fpga_idle_sg3.bit...
[INFO] [E300] FPGA image loaded

The failure output I got from running the python script shows that it can't
find "/mboards/0/xbar/gain_0/args/0/gain/value" and when I look at the
tree, there is no value instantiated by the probe. It only looks like the
furthest that the probe goes down in the mboards is
"/mboards/0/xbar/gain_0/args/0". I am assuming its something in the
arguments file not getting loaded, but everything appears ok to me on
glance in that XML file.

Regards,
Jon
