[Xenomai-core] cmd_write

[Xenomai-core] cmd_write

[Stefan Schaal]

Hi,

  I have been trying to test the functionality of the analogy_ni_pcimio driver on a NI6259 board. I am using a linux kernel 2.6.29.5 with the xenomai-head (rc5). Doing an a4l_sync_write to an analog output channel works fine. Now I am trying to use the cmd structure for writing to the same analog output channel, as done in the cmd_write progam (whose source I found in <xenomai_root>/src/util/analogy/cmd_write.c .

But I am getting the error as indicated below. Any idea why this happens? My own programming gets the same error.

Thanks a lot!

-Stefan


unix> /usr/xenomai/bin/cmd_write -v -d analogy0 -s 1 -c 0 -S 1

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: scan size = 2
cmd_write: size to write  = 2
cmd_write: command successfully sent
cmd_write: triggering failed (ret=-32)

Is there any kernel error messages ? Could you give us the last few 
lines of `dmesg` ?

This bug hapens randomly on a card to which I have a remote access.
The occurences were scarce, that is the reason why this bug is still
at the tail of my todo list.

On your board, I suppose it happens at every try. I will try to fix
this bug as soon as possible.
