The card will work as normal during firmware upgrade and when done, the user must manually
ask the card to reboot. This alternative methode is much faster then upgrading using Multicon
GYDA.
If firmware upgrade failes, it is possible to go back to factory default image. This is described in
Section 6.8 .
It is also possible to upgrade firmware by writing a new image on the microSD card. More about
this in Appendix A .
