Hi Philip and Thomas,
I just tried the new image from http://files.ettus.com/e1xx_images/current/
and the lpm module loads without error. The only problem now is that lpm
doesn't seem
to be resetting the dsp. The output below shows that the first program
(loopgpp) runs fine, but the second program (messagegpp) freezes. Even after
running lpmON/OFF, the second program still freezes. Any ideas why?
Best,
Leaf

This is my fault. The new image should work and I will check if I have the

The module failing to load is problematic. I'm surprised that the
dsplink module would load but not lpm. What is your kernel version?
I copied the lpm kernel module and utilities from another image onto
my current filesystem, and can confirm that the method works.
