I did wonder whether it was write protected also. there is a jumper by the epoxy on the flash ic which made no change in setting any global conditions. never got around to removing the epoxy to trace the lines properly

assuming you mean the led's on the atmega. They are not compulsary and not required for modchip to work. However, they do come in usefull if something isnt right as they indicate if they jtag detected cpu correctly, patched correctly and reset.

just a connection point, probably to install the initial bootloader which then fires the box off to install via tftp

yes im not sure why but its the box resetting (used to see it myself and certain circumstances made the box crash and reset).
Needs the reset to usb wire connecting and possibly the modified code incorporating reset patch programming to sort - altho that doesnt stop the box crashing but that can be worked around im sure (from memory is the wdt active which resets the box after x secs if tv2 crashes or hangs, this is prevented with the wdt patch in the nk.bin i think)

possibly, however its never going to work if the modchip isnt lighting the green led as its not detecting the cpu correctly and patching the ram to boot any software that isnt signed. the fact it does 'something' when grounding the line indicates the chip is programmed (perhaps correctly....) so my money is on wiring connections or jtag enable

Due to recent developments, just wanted to find out who was working on what as seems they may be light at the end of the tunnel regarding CE & Linux.
Seems pointless everyone reinventing the wheel to get either booting to some extent on their own hence me (re)asking the question so we(I) can pool the efforts to assist.
Have spoken to Mick and Neo who are probably CE based altho neo is looking for holes in bootloader for the non jtagable boxes and Hoernchen has made his intentions clear with low level linux work.
Just trying to make the playing field level and trying to sort out the red and green coloured bibs

no you have a lead from modchip (the reset pin) which normally goes to the usb and detects reset. you can 'fake' a reset by grounding the lead for a moment which should make the modchip repatch the bootloader which in turn makes the leds toggle, again, something is wrong if all the led's are off
10
if it goes green then id say yes, depends what its doing thereafter ?
11
no the reset pin which you connect to the usb chip.
remove the usb end of it (so the chip just has a floating lead connected to it) then momentaraly touch it to ground (any part of the chassis) - this should initiate a reset and make the leds toggle and at least change which indicates the chip is programmed

well has to 1 of
chip programmed ok
chip connected ok
jtag enabled
does it flash if you force the reset ?
13
from the README file with the chip hex & code..... :s
Green Yellow Red
0 1 0 Reset detected
1 1 0 CPU-ID OK
1 1 1 CPU entered Debug Mode
1 0 0 Patch OK / CPU left Debug Mode
0 0 1 An error occurs
at no point should ALL the led's be off so you deffo have an issue, sounds as tho it isnt going into debug mode, is jtag enabled and are wires correct ?

glad you checked all this 1st b4 buying the box lol
the current bt .net exe can be tweaked somewhat but not to any functional degree, but linux + others may be available with some developments done by some ppl far more talented than me !
15
need modchip to start with as that allows unsigned code and generally playing, no solution yet but watch this space...........
I know who you are
