DGX Corona V4 quick question

[Joo C]

I've been at it for hours now...help please

I've made multiple dumps of the nand and succefully wrote the DGX Ecc. Installed the post fix adapter and wired the DGX. I'm getting pulses that last about 2 seconds. I've got my monitor com wired through my usb pro2 but I'm getting endless pulses without a glitch after attempting different wire lengths. I've also written back the original nand and the console boots. Can someone please advise on the reason for bridging R2C6 and R2C7 and am I interpreting it correctly by soldering a wire across these two points?

Thanks in advance

Bridge the solder pads at R2C6 and R2C7 with solder.

This enables I2C access (pads E and F on the DGX).

Thanks for the feedback Bl4k3y - if the dgx is pulsing, can I assume that the bridge is correct?

No.

Thanks Martin - I will break out the multimeter

pics would be useful too.

Not necessarily - read my replies in this thread.

Update...bridging R2C6 and R2C7 did NOT work-this after letting the console run overnight with endless pulses. I then put 2 (100 ohm) resistors across these points and the console glitched within 20 seconds. Thinking that this may have just been a fluke I powered down the console and booted Xell 3 times, all within a minute! Also important to note that I was unable to write the glitched NAND with the resistors present and had to remove them.

That means you didn't bridge them properly to begin with. Resistors REDUCE the power on a circuit.

had you posted images this would have been easier to assist with. You shouldn't have used 100ohm resistors for the reason stated.

If I were you, I'd get into a habit of starting threads properly. That means with history, process, pics and logs as it's just a waste of everyone else's time (as well as your own).
