SD cartridge reader sortof works...

[petran1420]

Hello friends,

I just whipped up my first attempt at the cartridge extend-o-sd, using prerunnerseth's cartridge pcb (so intereference shouldn't be a problem). I wired everything up, and when I try to boot up, I get a signal to my hdmi screen I'm temporarily using, but I believe theres an error during boot. I've attached the screenshots from my 2 times trying to boot up.

Any suggestions? Did I not wire them up correctly? I added shrink tubing around each pin on the cartridge reader to make sure none of the wires were touching, and it boots up just fine using the sd slot built into the pi.

Have you tried a different micro SD yet? I'd start there and see if it is the SD fault, or hardware fault.

I actually had 2 SD cards and 2 cartridge pcbs. I tried all 4 combinations and one of them works, unfortunately its my 4GB card and not my 8GB card, blergh!

Even then, sometimes it doesn't boot and gives me the 'problem switching to high speed mode' warning. I may have to just forego this and use the rPi0 sd card reader...

do you have any pics or plans how you wired it in cos maybe one of the data lines is off

Not sure if thats any help. I apologize for reusing wire colors, I know its not best practice!

I can see some "what we call it as dry solder" if you have any flux just wipe some over the solder and melt the solder, This should give it better connection, also you may want to try and shorten the exposed wire like your video wire is touching ground,

lastly...why is that red wire for? that is coming from the 5V
