Re: Problems with the NI PCI-6110

Frank,

Thanks for the response, however I still get errors like :

kernel: A status: fifo_empty
kernel: ni_mio_common: DMA overwrite of free area:
kernel: ni_mio_common: ai error a_status=a4f2
kernel: ni_mio_common: wait for dma drain timed out

With the returned data being 0 or random large values (which I assume 
are data from random memory locations where I have stepped out of the 
array), even with setting my --read-buffer flag to values ranging from 1 
to 64MB.  I have 2gb of physical memory, so i doubt I am running out of 
it, and I'm only trying to capture 1.  Any further suggestions?

Doug
