4.4 Using MCI slot & USB Host Port
The following contents outline the usage of Eddy’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.
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" comm
ands 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 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/PI
N module using Eddy-DK.
Following example displays procedures for USB memory stick usage.
Insert the USB memory stick to USB host port and connect telnet.
Type in "fdisk -l " or "ls -al /dev/sd* " command to check USB memory stick is properly inserted.
Create a folder using ‚mkdir /tmp/usb‛ command.
Mount "/tmp/usb" folder using "mount -t vfat /dev/sda1 /tmp/usb" command.
Always unmount USB memory stick with "umount <mounted folder> " command, before removing USB memor
y stick from USB host port.
If more than one USB memory stick is connected using a USB hub, each memory stick would be recognized
as /dev/sdb1, /dev/sdc1, /dev/sdd1…. Each device must be mounted for proper use. Following displays an exa
mple of two USB memory stick connection with a hub.
