Problem Mounting SD Card
Equinoctum
Posts: 4
I am new to propeller and have been trying to make a barebones SD card reader. However, I am having issues mounting the SD card using FSRW 2.6. Attached is the circuit diagram and the file I have been using to test. Power and ground are drawn from a BoeBot board.
I have repetitively checked the connections for shorts and incorrect wiring, and have remade boards. I have tried using different propeller chips, prop plugs, and connecting the SD card to different pins. I am using a SanDisk 2GB Class 2 SD card, formatted Fat 16 (tried both quick and full formatting). On a Windows 7 x64 OS, I have tried using different USB cables and updating the VCP drivers. I have also tried running on Windows XP x32.
Every time I run the program I fail to mount.
Any insight would be greatly appreciated.

Here is the PCB layout:

I used a Yamaichi NMS011-2000-1 card connector from RS Components (493-2052).
It works OK with the FSRW 2.6 software.
I have also tried making different card connectors, and using various combinations of with/without 10k pull-up resistors.

You may need to try a different card.
Thank you so much everyone for all your help!! I can finally rest in peace tonight
