OK, I've had a look into LPC Linux. It appears to be an embedded development board platform which is out of my league.
If no one else answers from this forum, it might be better to put your query to the LPC forum.
Alternatively, you can try mounting the SD card from a command line and proceed from there.
mount /dev/mmcblk0p1 /mnt/sdcard
On some hardware, it's;
mount /dev/sdb1 /mnt/sdcard
mmcblk0p1 or sdb1 will depend on where the system puts the sd card reader.
You could do this from a bash script as well. You may need to use sudo in front of those commands to borrow root access although I suspect that, being an embedded system, it might default to root access unless otherwise directed.
