Hi All, 
  I tried vtuner on my router(mips arch), The system is running linux-2.6.21.5. i did two things:
1. Backport the usb dvb-t driver from the v4l. I seems the driver module loaded 
and device initialized success.
usb 1-1: new high speed USB device using ehci_hcd and address 2
usb 1-1: configuration #1 chosen from 1 choice
dvb-usb: found a 'Mygica D689 DMB-TH' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
DVB: registering new adapter (Mygica D689 DMB-TH)
DVB: registering adapter 0 frontend 0 (AltoBeam ATBM8830/8831 DMB-TH)...
dvb-usb: Mygica D689 DMB-TH successfully initialized and connected.
2. cross-compiled the vtuner-app and run vtunerd-mips on my router, but i met 
ioctl fail message:
root@OpenWrt:/overlay/D689# vtunerd.mipsel     
vtunerd: [738 ../../vtunerd.c:87]  info: S2API tuning support.

vtunerd: [738 ../../vtuner-dmm-3.c:60]  info: FE_GET_INFO dvb-type:2 
vtuner-type:4

vtunerd: [738 ../../vtuner-dmm-3.c:71] error: DMX_SET_SOURCE failed for 
/dev/dvb/adapter0/demux0 - Invalid argument
   Could anyone give me points to solver this issue? Thanks!

Few remarks:

1, I'm not expert in DMB-TH, but are you sure that you have compiled-in 
dvb-core subsystem with support for DMB-TH? I guess the original 2.6.21 has no 
support for it. But, of course, you can very easy backport dvb-core from some 
higher vanilla kernel. If you are sure about it, then ok and never mind my 
question.

2, You definitelly need another vtunerd binary. Original vtunerd.mipsel is 
solution for Dreambox set-top-boxes. They are using a bit modified DVB API 
subsystem and this is the main reason why it is not working for you.

I see you are croscompiling yourself, so do the same for vtunerd.mipsel. But 
don't forget to remove -DDREAMBOX_HARDWARE define from Makefile! 

If you have any troubles with it, let me know and I prepare binary for you.
