[QUOTE="ChefVortivask, post: 10347618, member: 644331"] I was able to probe the Wii U with the oscilloscope today and have some interesting findings to share. I didn't test with de_Fuse (just the Wii U as is), but now I have a much better handle of the oscilloscope. Starting with the CLK signal, it appears to me that the signal is fine and acting as it should. As stated previously: I've attached some pictures and you can see that the CLK signal which is the yellow wave corresponding to channel 1 is indeed a square wave. I noticed that upon powering on the Wii U it takes a couple of seconds for the CLK signal to respond (or start, not sure the proper terminology), but once it does it stays as a square wave with a frequency of 375 kHz. It never reached 3V3, only about 1.7 V. With the CMD signal (blue wave, channel 2) the wave shoots up around 3.1 V upon turning on the Wii U and stays there. I never observed the voltage change, let alone go down to 0 V. The frequency also fluctuates a lot, but it's possible that may be due to noise. It's possible it was at 400 kHz initially and didn't notice, but it shoots up to well beyond 52 MHz to several hundreds of MHz. I even saw it climb to over a GHz at some times. I also probed the D0 and D1 (channels 3 and 4, purple and green respectively) lines but didn't notice any change when powering on the Wii U. I take that to mean something is wrong as there probably should be some response from them. I've attached several pictures to give a better illustration of what I did and what was measured. I have a theory that it's possible that the D0 and D1 lines weren't responding and CMD was acting weird because the micro SD card isn't formatted or set up as an MLC, but I could be wrong. [/QUOTE]
