ZC.QingLong Secureboot Based on NXP S32K1XX
Product Description
ZC.Qinglong BootLoader is a self-developed program refreshing software (BootLoader) by ZCTechnology. Controllers using ZCQinglong BootLoader can achieve the update function of application programs through communication methods such as CAN, LIN, SPI, and UART. Currently, ZCQinglong BootLoader supports chips from NXP, Infineon, Renesas, ST, and other manufacturers, and also supports the program refreshing standards of various car manufacturers, offering customized development services.
Introduction

Currently, the electronic and electrical architecture of automobiles is becoming increasingly complex. With the electrification, intelligence, connectivity, and sharing of vehicles, the proportion of software R&D in automobiles is growing larger. The frequency of software updates is also increasing. Moreover, throughout the entire lifecycle of a car, including the R&D phase, production phase, and after-sales phase, software update functionality is required in each stage. Therefore, customer demand for software program updates is becoming more urgent.

Furthermore, with the implementation of the Internet of Vehicles, information security is gaining more attention. As chips serve as carriers of information, data protection within the chips is particularly important. ZC.Qinglong SecureBoot, based on the NXP S32K1xx platform, implements the security features of the BootLoader. By implementing SecureBoot, the controller can detect if the BootLoader program and application programs have been tampered with, ensuring the security of program updates, especially during the FOTA process.

Software Architecture

image.png

The ZC.QingLong BootLoader software implements a layered architecture, which is divided into the Hardware Driver Layer (HwDrv), ECU Abstraction Layer (EcuAbstr), System Service Layer (SysSer), and Boot Management Layer (BootManager). The entire software is modularized, where:

Ø  HwDrv

The Hardware Driver Layer implements the drivers for the chip's hardware modules and is dependent on the specific chip. Different chips require replacement of the drivers in this layer

Ø  EcuAbstr

The ECU Abstraction Layer is an abstraction of the ECU, including drivers external to the MCU。

Ø  SysSer

The System Service Layer implements functions such as communication, diagnostics, memory management, watchdog management, and security management.

Ø  BootManager

The Boot Management Layer is responsible for the scheduling management of the entire BootLoader software module and for managing the interfaces with the application programs.

The ECU's memory is divided into PFLASH and RAM. PFLASH is further divided into Application & Data and BootLoader areas, while RAM is divided into FLASH Driver and Data areas.
