I’ve got a Nintendo Switch that is giving me the, “microSD is not recognized,” error. I’ve confirmed the SD card is still functional as it reads on PC and other Switch’s. I ordered a new SD card reader off Amazon and popped that sucker in, but the Switch STILL can’t read microSD cards. I’m at a loss here. I thought for sure replacing the reader would fix the issue.
Has anyone had similar experience with this, or might have another avenue that I could try?
I have the same issue. Two readers and three SD cards later still doesn’t work. I wish I had an answer. I checked the MB SD Card Reader connection it seems fine. I guess I will have to pin out each circuit and see if there is some fault there. I’ll let you know if I’m successful.
Check the marked pads on the backside (Side-A). The red ones are the power delivery from the max77620A. If they are not present, the problem maybe at the max ic. The yellow is the enable signal. If the signal have no 1.8V the problem maybe at the soc. If both are present please check the PU ic (the one red marked spot with the six pins) and the cap and the both resistors left to the ic.
Hi, I have a similar issue with my switch and SD cards. I tried several sd cards and formatted then in fat32/exfat. The main difference is that my switch freezes when I insert the SD card. If the switch is powered off, I insert the SD card and then I turn the switch on, the switch stucks on the screen with the joy on logo. Do you have any hints where to start my diagnosis?
Well yesturday i have found out that i have used bad multimeter ( not showing voltages correctly) so got other one from a friend. Connected pcb to battery and powered it on and tested all points. So looks like i do have 3.3v on all spots that it should be and 1.8v on yellow pin… so there is power supplyed to sd slot… so im out of ideas why i get error “cant accsess sd card”. Soc problem? Looks like i’ll have to use it without sd card … Again thank you for your help and info!
I bought it new never used sd card… just after install of sx core at first sd slot worked but not allways switch would read the boot.dat file from sd (mostly from second try) and in the end ir doesint read sd at all.
