现在越来越多的客户，对于S32G PFE在master/slave的使用有了需求。 但是，PFE只有4个HIF接口，HIF0~HIF3，而PFE有3个EMAC口，以及LLCE2PFE也需要要给HIF，从而HIF成为一个关键资源。 同时，有些客户需要从A核，M核的业务考量，A核和M核的网络不仅要和外部设备进行通信，同时A核和M核内部也有通信需求，并且需要把业务报文和管理报文分离，这就对PFE master/slave的使用场景有了更多变化，以及对各种配置有了更多需求。 因此，针对PFE/Slave的几种使用典型的使用场景，进行配置。

在进行时钟同步时，目前S32G2/G3有一种很典型的使用场景： Grand master clock  <-> S32G PFE <-> 其余连接在PFE 某些 eMAC口上的设备 外部的grand master clock，连接在PFE的一个eMAC上，要同步S32G以及连接在PFE其余eMAC上的设备时钟。 但是S32G2/G3的PFE仅仅是支持timestamp，对于将S32G PFE设置成交换机使用时，PFE不能实现Transparent clock的功能。 因此，本文讨论将PFE + S32G SoC当作Transparent clock，以及将PFE + S32G当作boundary clock，来同步S32G以及其余部件的时钟。

i.MX RT1170 crossover MCUs are part of the Edge Verse™ platform and are setting speed records at 1 GHz. This ground-breaking family combines superior computing power and multiple media capabilities with ease-of-use and real-time functionality. For reducing the overall system cost, RT117x didn't have embeded flash, need external Flash as program storage and XIP place, NXP and third party like IAR, KEIL and Segger all provide mature tool to make Nor Flash‘s programing with their own flashloader, can fulfillment most customer’s application requirement, but still some users need to customize the flash programing algorithm due to programing speed optimization and difference of the nor Flash from different vendor and, such as SFDP support, QE bit's position, default sector size, DDR/OPI/QPI feature, default 3 Bytes/4 Bytes mode and also operating sequence, but the default Flashloader is based on the ROM API, it's hard to debug and customize as there is no source code. This reference demo will use source code Flash operation API instead of ROM API. In addition, it also add two new useful feature, first one is current Flashloader framework can't support some nor flash which need pre-configuration, such as Cypress's S25HL01GT, its sector size is not unified, need to config additionally. This reference demo give some function interface to implement it with 3 bytes/4bytes command mode and DDR/SDR mode, it also improve the original framework by adding read-erase-write demonstration code, which can help user to verify their customized Flashloader without need to copy to IDE every time, improve the efficiency greatly. Second advantage is it can support download flow‘s log generation, by default there is no log info in overall download flow, hard to locate which step(get configure/init/erase/program/verify) the failure occur, this demo code add log function to record every detailed download step, by which users can optimize their download speed, it's helpful for mass production. Developers can also debug and customize depend on their own specific requirement and different nor Flash.
