==== Restrictions =====
*** IPSec is not yet supported **
* Some issues with the Wi-Fi interface (instabilities, no fallback...) on Wirnet iFemtoCell
* When upgrading from KerOS firmware 4.x, all trustzone secrets are lost
* When upgrading from KerOS FW 4.3.3, a hardware reset is necessary for FW 5.x burner to correctly detect USB
* Update status for an update from KerOS FW 5.1.x, FW 5.2.x or FW 5.3.x is in error, but the update is working fine
