Linux / yamon setxenv - pflash write/erase timeout fails

02. Apr 2010, 17:26

Making a start on Linux on the old btv box (silver)  but hit a couple of problems....

First problem, can't get the modchip to react to the GND'd pins so only way to boot yamon or linux kernel by renaming them to nk.bin

Next prob, trying to set the parameters in yamon seems to fail.

YAMON> setxenv a.linux_cmd "console=ttyS0 root=/dev/hda3"
Original value: "console=ttyS0 root=/dev/hda3", New value: "console=ttyS0 root=/
dev/hda3"
Updating XENV block at 0x48000000********************************pflash write/er
ase timeout fails.
.

XENV verification OK.

setxenv by itself shows the value set, but it does persist after a reboot, which I gues is the whole idea of setting this.

Any ideas?

Cheers

WinCE / Removing SigCheckFilter in latest binary

20. Nov 2009, 23:34

Was given a working Setanta/ESPN card so thought I'd give it a go by grabbing the Viewing Card Enabled firmware.  On startup, BT recognises that my account doesn't have a viewing card and forces a firmware "update" for the not setanta version.  Tried to spoof the contentversion so that it wouldn't force the upgrade and it seemed to be working as was almost completely started up when it decided to do some content checks and rebooted into NR01

This is where I suspected that the signature checking had moved until later in the process and some research found the following

*Update*

The program for editing the registry must not be working properly..
I manually hex edited the hv's and replaced the ref's to the sigcheckfilter.dll with 0x00, binmodded the nk.bin, and..... the box booted with no file checking 

I was able to verify this by modding the splash logo.

I found a working tool for handling the hv files but was wondering what you changed?  Did you blank out the entire registry keys or just the value?

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\HDProfile\FATFS\Filters\MyFilter]
    "Dll"="SigCheckFilter.dll"
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash\FATFS\Filters\MyFilter]
    "Dll"="SigCheckFilter.dll"

I tried using an older firmware with the smartcard activated, but amongst the 12 less channels that the channels scan finds on the older firmware is the one that the smartcard actually unlocks...

Hardware / BTV / Modchip / Linux boot

16. May 2009, 16:55

Just a couple of question for anybody who has had a go with linux on BTV box...

Which pins need to be jumpered with GND to boot with Yamon/linux?
The readme with the modchip source suggests PD6 or PD7, while the modchip pinout diagram I used shows a jumper across GND and PB1 or PB2.
So which is it, I'm guessing I should go with what the readme suggests...

Anybody had success with BTV and booting linux?
is0-Mick, you suggested this didn't seem to work on btv http://www.t-hack.com/forum/index.php?topic=169.msg1528#msg1528 do you happen to recall which pins were you jumpering to test at the time?

BT have rolled out an update to add download functionality so that they can offer HD content.  They haven't mentioned much else about what the update includes but it might be worth seeing what else they have updated...

Software / XML Mods / Start.xml / UPNP-av

31. May 2008, 11:18

...
however this solution only allows to do modifications to the firmware. you still need to modify the firmware separately.
there is no patch or alternative application yet to make the box work without IPTV server, although it is possible to manipulate the
gui configuration files so that you can at least use the GUI and browse UPNP servers.

Do you remember what you had to do to get GUI changes to take effect?
I have been trying to make GUI changes on the BTV since I was able to load unsigned content.  Modifications to strings.xml take effect, but changes to Start.xml are ignored... either the box loads the menus live from BT or they are stored elsewhere in the box...  any ideas?

Hardware / JTAG problems on DIT9719

27. Apr 2008, 11:37

Finally got round to soldering up the JTAG on my box.. the small scale was actually easier than I thought... but so far no luck...
With the box powered off or without the jumper bridged (I forgot about that 1st time round  ) I get a CPUID of all 000000000s
When powered on and jp bridged, I get CPUID of all 1111111111s.
From reading through the german posts with similar results, it looks like I might have the DIT9719 equivelent of a X301t :-(  either that or I've somehow messed up the JTAG.

Any ideas where I might have gone wrong?  I followed the second jtag diagram for wiring the GND on the parallel port (pin20 and 25), do all the pins (18-25) need to be connected to GND?

Attached a pic of my micro-wiring (note the Dec 2007 date on the board)...

Any ideas?

Software / XML modification

14. Jan 2008, 14:50

Hello,

Are modifications possible to the XML and configuration files stored on the HDD or is it necessary to relace the NK.bin with a custom version first?

I see reference in the forum to patched xml, but it is not clear (to me) whether this can be acheived without JTAG or similar...

I'm trying to get hold of a spare box for "experimentation", but wondered it any straight XML modification had been attempted already?
