[SOLVED] SAIO - Working cartridge sd

Post by TheHappiestBug » Wed Jan 31, 2018 4:27 pm

I am going to use a cart sd in my build, but the pads on the SAIO and the pads on the cartridge sd board wants are different. Why? How do I fix this? (for reference, my cart board wants pads 15, 19, 18, 14, 16, 17, 8, and 5. The SAIO doesn't have 8 or 5.) Thanks!

A handy reference for pad numbers for anyone trying this Just got it soldered up today and it wont boot from the SD card in the cart.
I wonder are my cables too long?
This probably isn't a Kite issue but I'm hoping one of you fine folks will be able to help?
Attached are pictures of the wiring and solder points.
I've tested the GND and 3.3V they appear ok
Also tested continuity from SD card points to the cart reader - its beeping but I don't know what order they should be in.
The PRS Tech picture shows pretty clearly which pins go to which; Do any of you guys have an idea?
PS - pi boots fine when SD card is inserted into SD reader onboard the pi.

Just found this post ;

https://sudomod.com/forum/viewtopic.php?p=15341#p15341

Do you think I've wired the Cart reader incorrectly?
Should it be every other pin rather than every pin??

EDIT:

Yep I'm a moron,
Found a clearer wiring picture;

Sorry for the spam.
I just need to search more thoroughly.
Everything has been done before - you just need to spend the time looking.
Thanks all.

Hi, Im having the same problem like you.

Im just not soldering the wires directly to the pi but to an dummy SD Card that goes into to slot of the pi then.

Can you tell me which Pad (PP14-PP19, GND, 3,3V ) corresponds to which pin in the SD-Card reader?

THX!
