Abstract

A method for starting a system-on-a-chip, SoC, without read only memory, ROM, comprises the steps of receiving, by a processor comprised by the SoC, a reset signal, monitoring, by a monitoring component comprised by the SoC, a connection between the processor and at least a non-volatile memory, both comprised by the SoC, upon occurrence of a first read access of the processor to the non-volatile memory via the connection checking, by the monitoring component, whether a data value returned in response to the first read access via the connection conforms to a pre-set value, and if the returned data value differs from the pre-set value, stopping, by the monitoring component, operation of the processor.
