Is it okay to use 0B2223cP for ob2223ap?

Ob2223ap cannot be directly replaced by 0B2223cP, cP is the baseband of ROM, and ap is the version number of ROM, which are essentially different, so it cannot be replaced. AP and CP are important nodes in the development of automotive electronic E/E system. Traditional CP has strong real-time performance and can meet the needs of traditional ECU, but the network delay and interference caused by intelligence and networking can not meet the strong real-time performance. The original purpose is to avoid repeated development of software modules with the same or similar functions. Using a standard software platform independent of the system can shorten the time to market, reduce the development work, and develop more products from the same group of components, improve the product quality, and realize the decoupling of software and hardware. Whether it is AP AUTOSAR or CP AUTOSAR, the initial overall goal of the standard is the same: 1, to better manage the automobile ECU with increased functional complexity 2. to improve the quality and reliability of ECU software; 3. Improve the flexibility of product upgrading and shorten the time to market. Considering the main application scenarios of the two software architectures, the requirements for chip performance are: AP AUTOSAR can run on 64-bit high-performance processors, CPU, etc. , AP AUTOSAR can also run on virtual hardware, and AP AUTOSAR can run on chips with computing power higher than 20000 DMIPs. The software architecture of CP AUTOSAR is hierarchical, and there is an obvious relationship between the upper and lower layers.
