Wii U Stuck on Logo
Sorry for the late reply. This week has been a bit busy for me, but I do intend on doing this soon. I don't mind being a sort of beta tester as I feel a lot of this project has been experimenting and contributing to our knowledge of the Wii U and its hacking. I'll probably go with ISFShax since...- ChefVortivask

That could work too. Does de_Fuse need to remain installed for any of this? 1714263749 I realized you’re probably referring to ISFShax.- ChefVortivask

So at this point, I’m thinking I should probably pivot away from trying to have a working MLC and just use the SATA adapter and hard drive in place of the disc drive. As much as I want to keep the disc drive, it seems like we’ve pretty much exhausted all options at this point, aside from the LVS...- ChefVortivask

So since there’s no card to shake hands with, I would guess that there shouldn’t be anything on the DAT lines. I did notice however that if I tried probing DAT0 and DAT1, but not CLK (no probes connected), the signal looks far weaker than it does if I also probe CLK. There’s still a little...- ChefVortivask

I guess it was nothing then, but at least I learned something. It’s possible that CMD0 was sent out, but I may not have had the vertical scale set properly or it was just really fast. What about the signals on the DAT lines? Are those expected as well?- ChefVortivask

So I think I may have found the cause of the problem, or at the very least something that should not be happening. I decided to try probing with the oscilloscope with no micro SD card inserted in the slot. I also did not use de_Fuse and removed the SD card from the front just to be safe. If my...- ChefVortivask

I've never seen CLK go to 3V3. The highest I ever saw was when it went to 2.16 V when trying minute, but normally it is around 1.7 V. I've tried trigger on falling edge and I never captured it going higher than around 2 V. I've also stated this before, but just to reiterate since it's been a...- ChefVortivask

So I've been thinking about this for a couple days now, but is there any chance that the eMMC (the old Hynix one) could be interfering? We know that its CLK and CMD signals are completely cut off due to the pads being torn off, but let's assume that the eMMC isn't fully disabled. I'm not sure...- ChefVortivask

So based on all your comments for my oscilloscope traces, it's appearing to me that things seem to be working as expected. Obviously the CLK still isn't reaching 3V3, but it doesn't seem like any particular signal is showing any red flags or anything of concern. It looks like CMD can still be...- ChefVortivask

I didn't have a chance to try it out yesterday, but I did today. There definitely is some different activity on CLK as booting into the minute menu happens. There's initially this wave that may be square, but it's rise and fall times are so fast that it's hard for me to tell even when I adjust...- ChefVortivask

Sorry. It seems I was a little unclear and confusing in my wording before. I was also talking about CLK, not CMD. I only mentioned CMD when I referenced what we were originally thinking of trying (pull-up resistor between CMD and 3V3). I understand how that can be confusing though. Anyways, as...- ChefVortivask

If that’s the case, and it does make some sense based on what you said, would there be any fix for that? Originally we were going to put in a pull up resistor to drive it high, but if we need to drive it low, I’m assuming the same method of just soldering a resistor between 3V3 and CMD wouldn’t...- ChefVortivask

I soldered in a 1 kohm resistor between the 3V3 pad and the CLK castellated via. It doesn’t look the prettiest, but the multimeter seems to show everything to be fine. I tried probing with the oscilloscope again and it doesn’t look like anything changed. I saw activity on CMD the first couple...- ChefVortivask

I can give that a shot. I’m assuming it’ll be like what we had planned for CMD and I’ll be putting the resistor between CLK and 3V3? For the CLK point, I can’t use the pad on the NAND-AID right? It would either have to be the castellated via or the pad for the micro SD card slot (castellated via...- ChefVortivask

I think I understand what you meant by trigger. I was to set the trigger so that I would essentially record a specific event. I think the reason the CLK is "flickering" is because in those clips, I didn't have a specific trigger set. I was mainly focused on CMD since I wanted to see if there was...- ChefVortivask
