Just a shot in the dark, but do you have a video source connected to the video input port on the DM6446 DVEVM?

As you may image it does not work. After a while I figured out that it blocks on dequeuing buffers from the v4l device: ioctl(...VIDIOCQ_DQBUF...). To be more precise: videobuf_waiton() (which is a part of video_dqbuf()) returns with -EINTR. cat /proc/interrupts shows that there are no interrupts generated by the v4l module: [EMAIL PROTECTED]:/opt/dvevm# cat /proc/interrupts CPU0 0: 0 dm644xv4l2 8: 44042 davincifb 12: 1 musb_hdrc 13: 10125 EMAC 32: 4 free-run counter 33: 0 high-res timer 35: 73522 system tick 39: 1765 i2c 40: 2797 serial Err: 0 And yes, vpfe_isr() is not really called once (although register_irq returned with success). TVP5146 on the other seems to be working ok. I use S3(10)->OFF, means NTSC is supposed to be used by the kernel (from u-boot) Here's my u-boot environment: setboot=setenv bootargs mem=120M console=ttyS0,115200n8 root=/dev/hda1 rw noinitrd ip=dhcp video=dm64xxfb:output=ntsc bootcmd=tftpboot;bootm rootpath=/home/adam/filesys nfshost=10.5.0.5 bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=10.5.0.5:/home/adam/filesys,nolock mem=120M bootdelay=3 baudrate=115200 setenv=bootargs console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs video=dm64xxfb:output=NTSC; nfsroot=10.5.0.5:/home/rzubala/filesys,nolock mem=120M filesize=17628 fileaddr=80700000 ipaddr=192.168.16.85 serverip=10.5.0.5 bootfile=uImage stdin=serial stdout=serial stderr=serial ethaddr=00:0e:99:02:51:77 videostd=ntsc I've tried pretty much everything: I've recompiled the u-boot with (in my opinion) all VPSS_PSC enabled (both master and slave). Same goes for the kernel. From the point of configuration I think this is it, I have no idea what to do next... I'm starting to suspect that my DVEVM got damaged at some point. Maybe someone had similar problems? I would really really appreciate any help, and maybe uImage+u-boot that works 100%.? Please :) Best, -- Adam Dawidziuk Sentivision _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
