Corona v3 DGX Can't get CPU key

[Djirko]

Hello,
its not my first DGX install, but first install with postfix adapter. So i bridged the points ( 3 missing resistors ) to read the nand. After that i wrote DGX ecc ( also tried alternative one ). Installed postfix adapter, used suggested anchors and of course soldered DGX itself. Switched DIP 8 to ON and started console. Green light blinks few times ( about 5-20 times ) and then stops. Theoretically it should boot to xell at that moment, but i dont see xell on my router admin panel and jrunner doesnt find it with "scan ip range". Unfortunately i dont have nandx update cable, so i dont use COM monitoring. I already done about 10 DGX installs ( both trinity and corona ) and didnt have any problems with any of them.

This is my current jrunner log:

I attach my soldering photos. Sorry for blurry pictures, i didnt have better camera.

Its a miracle After maybe 50 tries, it somehow magically booted Would be interesting to know, why does that happened.
Is it possible, because i shortened cpu_rst wire to 8cm? ( It was about 14cm before that )

Go figure you spend all the time to make a good post and then it works.

Anything is possible if you lengthen or shorten wires, it would make things too easy if we could only use the same length wires.

Glad you got it going.

For DGX Corona, I use the shortest wires I possibly can. Not had a problem yet.
