Abstract

The present invention relates to a method for a self-boot of an electronic device, wherein an external component is accessible through an interface of the electronic device (), the method comprising, determining a boot mode for booting the electronic device, wherein the determined boot mode is defined as a secure boot mode; disabling the interface, thereby prohibiting access to the component through the interface, thereby defining a secure state of the electronic device; loading a first code comprising a sequence of executable instructions to be executed for booting the electronic device; loading a second code, the second code being encrypted; and decrypting the second code and executing the second code, thereby enabling the interface, and switching the electronic device from the secure state to a debugging state.
