DSP gateway build problems with 2.6.13.4

DSP gateway build problems with 2.6.13.4

[Richard Copeman]

Hi Everyone,

I suspect that much of this is down to my lack of understanding.

I have a 2.6.13.4 kernel which I can build and which runs nicely on my OMAP
5912 OSK board.

I downloaded dspgateway 3.3 and it comes with a patch from 2.6.12-omap1.
Some of the pathnames have been changed from here to 2.6.13.4. I don't know
enough yet to know which bits need patching to what level to get something
that I can build and run. Does anybody have a patch which I can apply to my
2.6.13.4 tree (preferably with idiot proof instructions for applying said
patch too :-) ) please?

Many thanks,

Richard.

	DSP Gateway has been merged with the OMAP kernel for quite some time
now, so the version of Gateway already in your 2.6.13 kernel would be
either the same as --- or possibly newer than --- the one in the 2.6.12
patch.  It would not be difficult to modify things so the paths would
match up, but in this case it is unnecessary.  Just recompile with
CONFIG_OMAP_DSP selected.

Hi Matthew,

Many thanks for the pointers. I re-built my kernel and it did link in the
dsp kernel objects. However, when I try to run

	dspctl start ex_task.out

on my target I get an error (some of which has been truncated by minicom)

Warning: none of /sys/devices/platform/dsp.0/ifver,
/sys/devices/platform/dsp0/<stuff missing here>.
(DSP Gateway driver is too old or not loaded)

I have grep'ed the header files and it is DSP Gateway 3.3 that has been
built. I built the ex_task.out and dspctl using the dspgateway 3.3 stuff I
downloaded from sourceforge. 

How can I check if the dsp gateway kernel object is loaded?
How can I get information about it's version?

Thanks,

Richard.

Hello Richard,

 Do you have the /sys directory? The dsp gateway needs
the sysfs mounted in the directory, as other drivers do.

 If not, please try

	# mkdir /sys
	# mount -t sysfs sysfs /sys

 Ishigami

Hi Ishigami,

I did not have a /sys directory. I created it as per your instructions but I
still get the same message from dspctl when I try to load the example.

I do not have a /sys/devices/platform/dsp.0 entry. /sys/devices/platform
contains:

i2c_omap	omap_ts	omapflash.0	serial8250		smc91x
omap_cf	omapfb	power		serial8250.0

Have I missed something important somewhere?

Also, how do I fix it so that this directory is automatically created and
mounted at boot time?

Thanks,

Richard.

G'Day,

	The directory should be there once you have created it, but to mount it
automatically add the following line to your /etc/fstab file:
none            /sys            sysfs   defaults        0       0

	If you already have it linked into kernel, then I am a little stuck as
to why it would not be creating the /sys/device/platform/dsp/ directory;
this should be automatically done, once you have sysfs compiled in and
mounted (as you have now done).

 Hmm, your kernel doesn't seem to have the dspgateway
driver. Could you double-check your kernel configuration?

 Add "mount -t sysfs..." at your "/etc/inittab" file. In most
linux system, this file acts as "autoexec.bat" used for
old MS-DOS days. For its syntax, see the url below

	http://www.busybox.net/downloads/BusyBox.html
	(look for "init" command)

 Hope this helps.

RE: DSP gateway build problems with 2.6.13.4

Hi,

Many thanks for the pointers. I've grep'ed my .config file and I can see the
following:

CONFIG_PROC_FS=y
CONFIG_SYSFS=y
#CONFIG_DEVPTS_FS_XATTR is not set
#CONFIG_TMPFS is not set
#CONFIG_HUGETLB_PAGE is not set
CONFIG_RAMFS=y


CONFIG_OMAP_DSP=m
# CONFIG_OMAP_DSP_MBCMD_VERBOSE is not set
# CONFIG_OMAP_DSP_TASK_MULTIOPEN is not set
#CONFIG_OMAP_DSP_FBEXPORT is not set

This leaves me confused on two scores - 
1) Why is /sys not being created?
2) Is "m" the correct option to include the DSP gateway driver?

If anyone has any clues for me....

Thanks,

Richard.

RE: DSP gateway build problems with 2.6.13.4

[Ishigami]

Hello,

 1) Why is /sys not being created?

 The simple answer is --- because it's designed so.

 2) Is "m" the correct option to include the DSP 
 gateway driver?

 There are two ways to build a driver --- as built-in
and as module.
 Option "m" means you build this driver as
module, which you need to explicitly install every time
your system boots-up.

 Until you get familiar with the steps, I'd recommend 
to use option "y". ( embedded the  drivers in your kernel )

 Ishigami

RE: DSP gateway build problems with 2.6.13.4

[Richard Copeman]

Hi,

I'm definitely getting closer with this now.. ;-)

I changed the CONFIG_OMAP_DSP option in my .config from "m" to "y" so now I
have the driver built into the kernel.

I created a /sys directory in my ramdisk root and added the appropriate line
to /etc/inittab so busybox creates all the correct entries under there for
me.

I built the DSPtools 3.3 for my host system (linux 2.6.13.4) using gcc 3.4.1
and built the ex_task demo application that comes with it. I placed the
binary fro this into my target /root directory.

I built the dspctl binary (cross compiled to arm with gcc 3.4.1) and placed
that in my target /sbin directory.

I boot that target, load he ramdisk, start the shell and enter:

dspctl start ex_task.out

I get lots of info scroll across my terminal and then the last few lines
give me:

Setting DSP reset vector to 0x0182a7
Releasing DSP reset
DSP configuration ... succeeded
Open taskdev: No such file or directory
/ #

My next question is... Can somebody tell me what I've missed please?

I checked into /dev/dsptask because the instructions for the demo say to cat
initial1.txt /dev/dsptask/test2 and I didn't have a test2 entry but I had
dsptask0 - dsptask9. I then tried:

Echo 'hello' > /dev/dsptask/dsptask2 and got:

mbx: ERR from DSP (TASKBUSY): 0x1002
mbx: ERR from DSP (IPBFULL): 0x00fe

Is this error related to the one above or something else I should worry
about?

Thanks,

Richard.
