Check if the home directory (ls /home/hadaq/) on the Etrax is mounted

When it is not possible to connect to given Etrax it could be that it has lost its flash content. Than it is necessary to axcess the board directly and change the hex switch (closse to the Etrax processor) to position A. Then the following steps has to be taken:
1. Make a power cyckle
2. Login on lxhades daq and go to /home/hadaq/etrax_soft/etrax_fs/devboard-R2_20/
3. su
4. . init_env
5. boot_etraxfs -d eth1 -F -i ./fimage
6. when flashing the flash is finished go back to position 0 on the hex switch
7. make a power cyckle, now the board should be accesible. If not exchange it with spare one (should be in the counting house)
