The usrp / gr-usrp hacking continues...
If you're tracking CVS, please update usrp and gr-usrp.
Prior to building usrp, you'll probably want to do a
"rm -fr PREFIX/share/usrp" to avoid possible confusion down the road.
I've added provisions that allow code to specify the
firmware and fpga files that are to be loaded. In addition, we are now
shipping *two* standard fpga images, one that contains 2 Rx paths with
halfband filters and 2 tx paths (the default) and one that contains 4 Rx paths
without halfbands and 0 tx paths.
The names of the fpga and firmware files have also be reworked.
Now after updating and installing you get something like this:
[EMAIL PROTECTED] multi-antenna]$ ls -lR /usr/local/share/usrp/
/usr/local/share/usrp/:
total 8
drwxrwsr-x 2 eb wheel 4096 Feb 18 19:53 rev2
drwxrwsr-x 2 eb wheel 4096 Feb 18 19:53 rev4

-rw-r--r-- 1 eb wheel 171213 Feb 18 19:53 std_4rx_0tx.rbf
/usr/local/share/usrp/rev4:
total 368
-rw-r--r-- 1 eb wheel 19840 Feb 18 19:53 std.ihx
-rw-r--r-- 1 eb wheel 175896 Feb 18 19:53 std_2rxhb_2tx.rbf
-rw-r--r-- 1 eb wheel 171213 Feb 18 19:53 std_4rx_0tx.rbf
std.ihx is the FX2 firmware. [Previously called usrp_firmware.ihx]
std_2rxhb_2tx.rbf is the FPGA image with 2 Rx paths with halfbands & 2 tx paths
std_4rx_0tx.rbf is the FPGA image with 4 Rx paths w/o halfbands & no tx paths
The default default is to load std_2rxhb_2tx.rbf.
You can specify the fpga filename to load in the constructor like this:
[EMAIL PROTECTED] usrp]$ python
Python 2.4.1 (#2, Nov 11 2005, 12:26:27)
[GCC 4.0.1 (4.0.1-5mdk for Mandriva Linux release 2006.0)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gnuradio import usrp
>>> u=usrp.source_c(0, fpga_filename="std_2rxhb_2tx.rbf")
>>> u.nddc()
2
>>> u.nduc()
2
>>> del u
>>> u=usrp.source_c(0, fpga_filename="std_4rx_0tx.rbf")
>>> u.nddc()
4
>>> u.nduc()
0
>>>
In addition, these environment variables override the default defaults:
USRP_FPGA=my_fpga_file.rbf
USRP_FIRMWARE=my_firmware.ihx
Also, if USRP_VERBOSE=1, you'll get chatty messages giving the
fully resolved pathnames to the firmware and fpga files.
That's it for now!
