Hi! When running the 'test_usrp_standard_rx' or _tx programs contained in the usrp-0.8 tarball, I get
[EMAIL PROTECTED]/7 (21:54) 2.5/usrp-0.8/host/apps > ./test_usrp_standard_rx
RX d'board A: Basic Rx
RX d'board B: TV Rx
fusb::pending_remove: failed to find urb in pending_rqsts: (nil)
zsh: 10309 segmentation fault ./test_usrp_standard_rx
This is on a dual opteron 246, running debian-amd64 and a vanilla
2.6.12-rc2 kernel.
strace'ing the program, I get the following last lines:
ioctl(3, USBDEVFS_SUBMITURB, 0xd1c940) = 0
ioctl(3, USBDEVFS_CONTROL, 0x7fffff800630) = 0
ioctl(3, USBDEVFS_CONTROL, 0x7fffff800670) = 4
getrusage(RUSAGE_SELF, {ru_utime={0, 6998}, ru_stime={0, 8998}, ...}) = 0
ioctl(3, USBDEVFS_REAPURBNDELAY, 0x7fffff7fc630) = -1 EAGAIN (Resource
temporarily unavailable)
ioctl(3, USBDEVFS_REAPURB, 0x7fffff7fc630) = 0
write(2, "fusb::pending_remove: failed to "..., 65fusb::pending_remove: failed
to find urb in pending_rqsts: (nil)) = 65
So it seems like the REAPURB ioctl returns a NULL-pointer and aborts.
Does anyone have an idea what's going on?
