This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff.

SD card FAT16 with RCM3100 - tarisltd - May 14 7:31:48 2009
Hello,
I connected SD card on the RCM3100 and changed CS control in SDFLASH.lib. I tried to run the example SDFLASH_INSPECT.C and it works fine!!!
But I can't run any examples SD card with FAT (DC9.62), because I get messages:
"Board type does not support FAT filesystem."
"You need to define _DRIVER_CUSTOM etc."
Did anybody try to connect SD card with FAT on the board which does not support SD card (for example RCM3100)? Could you help me...
Best regards

Maybe it will be useful for someone. I did it. Now SD card with FAT works fine on the RCM3100 core. I made a few changes in fat_config.lib. See below:

It need to insert RCM3100 board type in section *** Built-in vs. external serial/nand mass storage flash board specifics ***. See below:

#if (_BOARD_TYPE_ & 0xFF00) == (RCM3300A & 0xFF00) || \

It is evident that you must change SD card CS control in SDFLASH.lib, because it was made special for RCM3900 core which drive CS with BUFEN pin!! If you are going to use card detect pin you should change defines for card detect pin.
