How-To connect an MMC/SD adapter to the APF9328 (through DevLight board)
For instructions on how to use MMC/SD on Linux, see MultiMediaCard page.
Adapter board
We have designed a small adapter board with an MMC/SD connector on it. You need to connect the signals listed in the table below to the APF9328DevLight board one. The WP and CD_SW signals are optional and must be connected to free IOs if used.
Top view:
| Adapter Pin | Desc | Adapter Pin | Desc |
| 1 | +3.3V | 2 | SD_DAT2 |
| 3 | SD_CMD | 4 | SD_DAT3 |
| 5 | SD_CLK | 6 | SD_DAT0 |
| 7 | WP | 8 | SD_DAT1 |
| 9 | CD_SW | 10 | GND |
Remarks:
- Pin 1 (rectangular pad)
- WP: write protect
- CD_SW: Card Detect switch
