Title: Reset gremlins
Post by: Herman on 02. Sep 2008, 09:06
Having recently adapted iso-mick's new bt vision reset point near the usb controller of the pcb I have seen a very unreliable rebooting process and am wondering if anyone else has seen the same ?
Via crashing the box, i am able to instigate a reset (via wdt not being polled iirc)
I get the NR01 'Box is having difficulties' screen and occasionally it reboots (led can show a long reset lit period, then NR01 on screen, then all 3 lit, then reset it again and box boots)
Normally box resets, leds sequence and it goes to green as in exited ok, but screen shows nr01 and eventually wipes hd partition :(
However this is at best sporadic so far from ideal.

I tried playing with the source altering the PATCHWAITTIME in x30Xtmodchip.h.
lowering didnt seem to help altho i kindof got a reset quicker but failed consistently at 60 which seems too fast for initial bootup and hd spinup.

Just curious to what other btv users see / get when using the new usb reset point please

No problems here, and i've modded a few of these for people who were interested in playing.

Are you using the same power points? from near the PSU?

Maybe its a power problem?

there are 2 points on the chip to join to gnd (8+22) and 2 to 3.3v (7+20).

mick re my 3.3 Vs yours = same effect.
curiously, i see nr01 BEFORE the reset led goes out and patching it attempted (which succeeds but is too late) which is the DELAY counter in effect.

I reckon fuse setting are next issue.....

The chip should kick in about 2-3 seconds after it gets a reset. Thats what mine does.
Have you got LED's on it to show what it's doing?

http://www.t-hack.com/forum/index.php?topic=47.msg1170#msg1170 Pins  17,18,19 to GND. Works fine if you use just one resistor on the GND side for all three LEDs.

are you trying to inject the nk.bin fron vs8 ? if so then its not required.
the svn contains a modified booterce which allows execution of tv2clientce2.exe from /hard disk/tv2 instead of from within nk.bin which saves lots of hassle
