The IO interface for SDMC/NAND seems to be very similar to the DSi; see libnds for [http://sourceforge.net/p/devkitpro/libnds/ci/master/tree/source/arm7/sdmmc.c sample code] and [http://sourceforge.net/p/devkitpro/libnds/ci/master/tree/include/nds/arm7/sdmmc.h documentation]. | The IO interface for SDMC/NAND seems to be very similar to the DSi; see libnds for [http://sourceforge.net/p/devkitpro/libnds/ci/master/tree/source/arm7/sdmmc.c sample code] and [http://sourceforge.net/p/devkitpro/libnds/ci/master/tree/include/nds/arm7/sdmmc.h documentation]. | ||
3DS SDMC/NAND IO registers are located at 0x10006000 and apparently mirrored at 0x10007000. It seems the 0x10007000 mirror is never used on retail units. | 3DS SDMC/NAND IO registers are located at 0x10006000 and apparently mirrored at 0x10007000.
