摘要
A method for starting a system-on-a-chip, SoC, without read only memory, ROM, comprises the steps of receiving (S1), by a processor (10) comprised by the SoC, a reset signal, monitoring (S2), by a monitoring component comprised by the SoC, a connection (12) between the processor and at least a non-volatile memory (11), both comprised by the SoC,upon occurrence of a first read access (S3) of the processor to the non-volatile memory via the connection checking (S4), by the monitoring component, whether a data value (DV1) 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 (S5), by the monitoring component, operation of the processor.
