micro SD interface[edit | edit source]
Description[edit | edit source]
The micro SD interface available on the Evaluation Kit at the connector J26.
J26 is a Micro-SD card header. This interface is connected to the USDHC2 controller of the i.MX8M Mini/Nano CPU.
Signals[edit | edit source]
The following table describes the interface signals:
| Pin# | SOM Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|---|
| 1 | J10.79 | SD_DAT2 | Data 2 | |
| 2 | J10.81 | SD_DAT3 | Data 3 | |
| 3 | J10.83 | SD_CMD | CMD | |
| 4 | - | 3V3 | +3.3 V | |
| 5 | J10.85 | SD_CLK | Clock | |
| 6, 12 | - | DGND | Ground | |
| 7 | J10.75 | SD_DAT0 | Data 0 | |
| 8 | J10.77 | SD_DAT1 | Data 1 | |
| 9, 10, 11 | - | SD_SHIELD | Shield | |
| 13 | J10.177 | EIM_D19 | Card detect | SD2_CD_B on i.MX8M Mini/Nano |
Device mapping[edit | edit source]
The microSD card is mapped to /dev/mmcblk1. The available partitions are shown as /dev/mmcblk1p1, /dev/mmcblk1p2, etc.
Device usage[edit | edit source]
The device can be mounted/accessed as a standard block device in Linux.
