the transcend wifiSD cards all run the following script in
the embedded linux setup they ship on if power is applied to the card:
if [ -f /mnt/sd/autorun.sh ]; then
echo "running autorun.sh"
sleep 1
chmod 777 /mnt/sd/autorun.sh
/mnt/sd/autorun.sh
fi
so to gain access to the cards linux install we just need to format it with vfat,
put http://busybox.net/downloads/binaries/latest/busybox-armv5l into /
and add the following autorun.sh script next to it:
cp /mnt/sd/busybox-armv5l /sbin/busybox
chmod a+x /sbin/busybox
/sbin/busybox telnetd -l /bin/bash &
apply power to the card, attach you laptop to the WifiSD WLAN and run
telnet 192.168.11.254
