Abstract

The invention provides a method for upgrading a system-on-chip (SOC), which is applied to a target central processing unit (CPU) core, the SOC comprises at least two CPU cores, the target CPU core is one of the at least two CPU cores, and relates to the technical field of computers, in particular to the technical field of the system-on-chip and intelligent driving. According to the specific implementation scheme, a preset configuration file is read; the role of the target CPU core is determined based on the preset configuration file, and the role comprises a master core or a slave core; executing one of the following two according to the determined role: in response to the fact that the role is determined as a main core, flashing the main core according to a detected upgrading instruction from the outside of the SOC; in response to determining that the role is a slave core, communication external to the SOC is stopped.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to the field of system on chip (System on Chip, SOC) and intelligent driving technology, and in particular to a method and device for upgrading a system on chip and an automatic driving vehicle. Background technique [0002] With the rapid development of intelligent driving technology, higher requirements are placed on the processing capabilities of the vehicle. In order to meet the performance requirements, SOC has gradually been widely used in vehicles. [0003] In the prior art, a Microcontroller Unit (MCU) usually appears in the form of heterogeneous multi-cores, and its upgrade process usually involves a fixed master core exchanging information with the outside world and flashing other slave cores. The multi-core involved in the above upgrade process has a fixed master-slave structure, and the flashing direction is only from the master core to the slave core. Cont...
