Hi Jan, I have two USRPs to test with, one a Rev 3 and one a Rev 4.1. Both have the same behavior, except that one shows version 0.04 and the other 0.02 when I first plug them in (in the system profiler). Then, I run test_usrp_standard_tx, the firmware uploads, i.e. the LEDs start to blink slower, but the system profiler still shows the old values, i.e., they stay at "Vendor-specific".
I will try to see if I can enable some more debug information. Thomas On 7/29/06, Jan Schiefer <[EMAIL PROTECTED]> wrote:
Hi Thomas, I am using gnuradio+USRP on a MacBook Pro under 10.4.7, this setup should be very similar to yours.I have a version 3b USRP, with a BasicRX and a BasicTX board. Have you checked out http://comsec.com/wiki?UsrpInstall ? When I plug the USRP in my system, before it loads any firmware (i.e. before I run any usrp-related program), I see the following in the System profiler (Apple logo/About This Mac, click More Info... , Hardware/USB, USB High-Speed Bus/Vendor-specific Version 0.02, etc etc Product ID 0x0002, Vendor ID 0xfffe. After running test_usrp_standard_tx, this information changes From "Vendor-specific" to "USRP Rev 2", the version changes to 1.02 and there is a "serial number" string of all zeroes. Does yours show the same information in the System Profiler? Also, what does it say if you go to the usrp directory and run a "svn up"? Mine says "At revision 832."
