Hello at all, i have installe r jtag 1.1 on jasper a few yaer ago. All work good but in the last time i have a problem. Chip blink and glitch, but no video.I have checked switch in the jtag alt v 2 with multimeter and recognize that all two switch (on off) and other where i select (on off or capacitor in the middle way) don' t have continuity. I can solve situacion removing qsb v 2 and using wire. I know that is possible, but don' t remember how. Thanks

You can use AUD_CLAMP JTAG wiring underneath the board.

I can't remember what diodes and resistors are needed, but there is plenty of information available online explaining this.

You also need to make sure that you build the hacked image with an AUD_CLAMP SMC (tick the AUD_CLAMP box in J-Runner before building the image).
