Hardware details on How-To use MMC/SD/microSD cards on APF boards. For APF9328 DevLight you will learn how to connect an MMC/SD adapter/connector.
SDCard, MiniSD, and Transflash/MicroSD are all the same devices but in different package shapes and are all pin compatible.
On Armadeus boards, MMC are controlled in 1 bit MMC mode and SD/MiniSD/MicroSD in 4 bits SD mode.
We don't use MMC/SD in slow & error prone SPI mode.
Note: For instructions on how to use MMC/SD on Linux, see the MultiMediaCard page. (Here you will only find hardware details) |
Contents
Adapter board (for APF9328DevLight 1.0 or your custom board)
We have designed a small adapter board with a push-pull MMC/SD connector on it. You need to connect the signals listed in the table below to the corresponding one on your DevLight board. The WP and CD_SW signals are optional and must be connected to free i.MXL GPIOs, if used.
Signals name (Top view with MMC connector on the right):Adapter Pin | Desc | Adapter Pin | Desc |
---|---|---|---|
1 (square) | +3.3V | 2 | SD_DAT2 |
3 | SD_CMD | 4 | SD_DAT3 |
5 | SD_CLK | 6 | SD_DAT0 |
7 | WP (option) | 8 | SD_DAT1 |
9 | CD_SW (option) | 10 | GND |
Remarks:
- Pin 1 (rectangular/square pad)
- WP: write protect
- CD_SW: Card Detect switch
If you don't want to buy such an adapter or don't have a MMC slot (and are a hacker ;-) ), you can still try this link:
On an APF9328DevFull board, there is already a MMC/SD connector
So nothing special to do.
On APF9328DevLight 2.0, APF27Dev, APF51Dev & APF28Dev boards, there is already a microSD connector
So nothing special to do.
