hi...
just out of curiosity, are there any good images available from the PCB of the Philips DIT9719 ?
I Will upload some, just need to find my Camera.
missing since christmas
I have uploaded a so-so image to the wiki.
Great,
but whats the black "socket" in rear left edge.
For all people, who don't find the pic,...heres the link:

This is a slot for a viewing card and a smart card, they use a viewing card for premium dvb-t
I will upload a different image with breakdown of board
I like how they covered the flashrom in this white stuff ;)
not sure if that makes any sense, since the content of the rom will be most likely encrypted anyway... but looks nice :)
that empty connector named "1300" just left of the SMP could be a good candidate for a JTAG interface
I was looking towards the right of the SMP at the port 1052
One could be Uart the other JTAG
Found it - (almost certain) it is below 1300 - 1301.... It's even marked with pin 1 and pin 14.... Don't know how I missed it before.
Will be brave and solder some pins onto it and give it a shot.
you should check if the even pins are all GND... if not, it is unlikely to be a JTAG port.
Harsh lesson learned.... never solder directly onto a board without using a low voltage soldering iron.
Managed to strip the tracks of the ports..... luckily it was my spare box, and suprisingly it still works.
Might have to take a file to the SMP chip now to get things moving.
did you check if the port is actually the JTAG ?
no, my only way of testing is to connect up and hope for the best.
sounds risky...
using an ohm-meter to check against GND and also the JTAG traces on the CPU is not too difficult and might save your box ;)
Im a fly by the seat of my pants type of guy though.... :'(
Hi
Another Brit here. I've been eyeing up a BT Vision box as a replacement for my mythbox which keeps screwing
up so it's no longer "girlfriend approved".
I'm not a member of BT, so the box apparently won't work unless it's connected via BT Broadband. Is there a way
using the modding described in the wiki for the x300t to bypass that check?
Sorry if it's a dumb question.
I assume you just want to use DVB-T (DTT) ...
technically the dit9719 and x300t are very similar, but I think no one found the JTAG port on the PCB of the dit9719.
with very good soldering skills, you might be able to wire up the JTAG directly on the CPU, but that is not recommended.
anyway, if you have that step done, then the next problem is the bootloader, which is most likely different (but similar) to
that of the x300t. the bootloader needs to be patched to allow running modified files.
then there is a last problem, which is that the application does not fully initialize if it cannot connect to the IPTV server.
the DVB-T does not seem to work correct if the application is not fully initialized.
Yes - ideally, I'd like to exploit it's HDMI / Optical-out and potential media sharing capabilities.
Is hacking it so that initialises without connecting to the BT Vision server out of the question?
that should be possible... but it has not been done yet.
Hi All,
I'm another BT Vision / Philips DIT9719 owner. Ultimately I'd love to get it running Linux as a hackable PVR but from my browsing on the net I haven't seen much to do with the SMP86xx processors and Linux (well devices running Linux where the makers have released the source). Or whether its possible to even move it from Windows CE to Linux.
From searching on the web I found a Teac PVR in Australia that seems to be built from a similar platform that runs linux here - http://www.teac.com.au/file/product_manual_496.pdf and from a firmware I found this company that seems to have created their firmware and releases (some pretty ancient) Linux stuff but not sure of how much use it is. Link here http://netgem.com/en/supportLinux.php
Anyway, there's another person looking to hack :)
Peter
well there are serveral devices with SMP863x running Linux now.
Popcornhour
Dune HD
Freebox HD
the netgem HD is also known, but they use an old 2.4 Linux
the others did not release their kernel sources.
anyway, it is possible to run Linux on any SMP863x, but you need some hardware adjustments to pull this off.
it is currently being worked on to get the Linux Kernel running on the x300t WinCE box
