Reset gremlins

[Herman]

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?

I was just about to reply
You beat me to it..

resistors - pah !
chip pin to gnd works nps

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
