Dear all,
I have followed your advice and just tested with the following
kernel/xenomai versions:
Linux 2.6.38.8-xenomai-2.6rc4 #1 SMP PREEMPT Thu Sep 29 16:17:41
BRT 2011 x86_64 GNU/Linux
Now both "cmd_read" and my own code are running, but "a4l_async_read" reads
either garbage or either value of 0 or 0x8000. In order to make cmd_read
work with my board I had to make the following changes to the code:
--- cmd_read.c.orig2011-09-29 16:40:50.0 -0300
+++ cmd_read.c2011-09-29 16:41:04.0 -0300
@@ -66,8 +66,8 @@
.start_arg = 0,
.scan_begin_src = TRIG_TIMER,
.scan_begin_arg = 800,/* in ns */
-.convert_src = TRIG_TIMER,
-.convert_arg = 50,/* in ns */
+.convert_src = TRIG_NOW,
+.convert_arg = 0,/* in ns */
.scan_end_src = TRIG_COUNT,
.scan_end_arg = 0,
.stop_src = TRIG_COUNT,
otherwise the drive would complain about "the driver cmd_test failed" or
something like that, because my board has 8 parallel ADCs.
If I run my program (see attachment) and call dmesg I can see:
[ 641.237710] Analogy: analogy_ni_pcimio: ni_ai_cmd: start
[ 641.237718] Analogy: analogy_ni_pcimio: ni_ai_cmd:

I just checked my setup with our RTAI/comedi code and it is properly
working. The input card is attached to a 3Hz sine wave generator with 1V
peek-to-peek. If I run the attached program, the output looks like this:
Analogy device analogy_ni_pcimio.
Channel 0 has 16 bits and 1 different ranges
32768
32768
32768
32768

[...]
32768
Any help on debugging this would be greatly appreciated.
Sincerely,
Fernando
