Problems building DSP gateway on 2.6.15

Problems building DSP gateway on 2.6.15

[Richard Copeman]

Hi,

 

I have just built 2.6.15 kernel with 2.6.15-omap1 patch. I included the DSP
gateway support in my "make xconfig" stage. I downloaded the utils and apps
from sourceforge for dspgateway 3.3 and built those successfully. I am using
Uboot 1.1.1 to setup my 5912 OSK board and then downloading the kernel and a
ramdisk via JTAG to target memory. Console is via serial port and minicom to
my host PC. My ramdisk is created with:

 

set -x

SIZE=8192

DEV=/dev/ram

ROOTFS=/usr/src/5912/rootfs2.6

/sbin/mkfs.ext2 $DEV $SIZE

mount -t ext2 $DEV /mnt/ram

cd $ROOTFS

cp -av . /mnt/ram

df /dev/ram

umount /mnt/ram

dd if=$DEV bs=1k count=$SIZE | gzip -9 > ramdisk.image.gz

chmod 666 ramdisk.image.gz

 

 

 I try to do: dspctl load ex_task.out but it tells me that:

 

Warning: none of /sys/devicesplatform/dsp.0/ifver,
/sys/devices/platform/dsp0..

(DSP Gateway driver is too old or not loaded)

open control device: No such file or directory.

 

In /sys/devices/platform I have: i2c_omap.1, omap_mcbsp.1, omapflash.0,
serial8250.0, omap-keyboard, omap_t2, power, smc91x, omap_cf, omapfb,
serial8250 and uevent.

 

In /dev I have: console, tty, tty0 and ttyS0

 

lsmod shows no modules loaded.

 

I'm sure I have missed a step along the way here but I can't find it. Can
someone point me in the right direction please?

 

Thanks,

 

Richard.

There should be /sys/devices/platform/dsp directory if the DSP Gateway is
compiled in the kernel. 
Do you see "OMAP DSP driver initialization" in the boot message?
If yes, DSP Gateway is in your kernel and I suspect you have a problem
in your fs. Otherwise your kernel doesn't contain DSP Gateway.
Didn't you miss to do 'make uImage'? (Since sometimes I do. :))

Toshihiro san,

Thanks for the pointer.
There is no OMAP DSP Gateway message displayed during my startup.
I do not do "make uImage". I use a JTAG debugger to download vmlinux
directly to RAM. What does "make uImage" do for me?

Thanks,

Richard.

If you use JTAG debugger for download you don't need 'make 
uImage'. You only need this if you use bootloader U-Boot to 
download and start the image.

Yes, Richard-san, I've missed you'd explained you are loading the kernel
with JTAG debugger. Sorry for that.
But anyway your kernel doesn't contain DSP Gateway,
so you should check you are loading correct kernel image.

When I load my kernel through JTAG, I use vmlinux for symbols besides
using zImage for the binary to run, to save download time by using a
compressed image. In that case I need to replace both vmlinux and
zImage on the debugger host.
Could this kind of things happen on your situation?
