TMS570LC4357: 关于EMAC驱动EMACSwizzleData问题

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN, TMS570LS3137

      您好,目前我在开发TMS570LC4357的EMAC模块驱动,我首先使用HALCoGen生成驱动代码,发现HL_emac.c驱动代码里有一个函数EMACSwizzleData,

我对比了HALCoGen生成的TMS570LS3137的EMAC驱动代码,发现没有函数EMACSwizzleData,请问3137和4357在写EMAC CPPI RAM上是有不同吗?

在操作4357的EMAC CPPI RAM时,手册中 Figure 32-5. Basic Descriptor Format  是否都需要先使用EMACSwizzleData 进行翻转字节?

        多谢!
