See the print-outs below for the problem we have.

Thanks so much for looking into this!

Using the cmd_write() function that you provide in analogy, we get the 
following problem:

r...@xenomai:/usr/src/xenomai/src/utils/analogy# ./cmd_write -v
cmd_write: device analogy0 opened (fd=0)
cmd_write: basic descriptor retrieved
         subdevices count = 14
         read subdevice index = 0
         write subdevice index = 1
cmd_write: complex descriptor retrieved
cmd_write: channel 0
         ranges count = 3
         range's size = 16 (bits)
cmd_write: channel 1
         ranges count = 3
         range's size = 16 (bits)
cmd_write: scan size = 4
cmd_write: size to write  = 400
cmd_write: command successfully sent
cmd_write: triggering failed (ret=-32)

r...@xenomai:/usr/src/xenomai/src/utils/analogy# dmesg -c

Another problem we have is with the --mmap option:

r...@xenomai:/usr/src/xenomai/src/utils/analogy# ./cmd_write -v --mmap
cmd_write: device analogy0 opened (fd=0)
cmd_write: basic descriptor retrieved
         subdevices count = 14
         read subdevice index = 0
         write subdevice index = 1
cmd_write: complex descriptor retrieved
cmd_write: channel 0
         ranges count = 3
         range's size = 16 (bits)
cmd_write: channel 1
         ranges count = 3
         range's size = 16 (bits)
cmd_write: scan size = 4
cmd_write: size to write  = 400
cmd_write: buffer size = 65536 bytes
cmd_write: a4l_mmap() failed (ret=-22)


r...@xenomai:/usr/src/xenomai/src/utils/analogy# dmesg -c
