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 Note: For instructions on how to use MMC/SD on Linux, see the MultiMediaCard page. (Here you will only find hardware details)


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.

Top view, connector on the left
Signals name (Top view with MMC connector on the right):
MMC Adapt pinout.jpg
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.

Test method

Use test script (media_perf.sh) located in armadeus/target/test/mmc/. Install Armadeus TestSuite and then launch it:

# cd /usr/bin/testsuite/
# media_perf.sh speed
