4.4 Eddy-S2M/Pin’s MCI & USB Host Port
The following contents outline the usage of Eddy-S2M/Pin’s MCI & USB Host Port.
Using MCI slot
MMC and SDCards can be used through MCI slot.
Please note that MCI and SDCard must be inserted before power is induced to Eddy-S2M/Pin module.
MMC or SDCards are automatically recognized as a new disk space in " /tmp/mmc " folder. If memory
card is not inserted to the MCI slot, " /tmp/mmc " folder will not be created.
To check memory card’s current disk space information, type in "du -sk /tmp/mmc" or "df /tmp/mmc"
commands via telnet. Following example displays status of a memory card with 1GB memory storage
capacity.
Using USB host port
An USB memory stick or USB hub can be attached to Eddy-S2M/Pin module’s USB host port. If other
USB devices are to be attached to this port, device drivers for the devices must be first created and
loaded to Eddy-S2M/Pin module using Eddy-DK.
Following example displays procedures for USB memory stick usage.
