关于F28377D双核寄存器控制问题

Other Parts Discussed in Thread: C2000WARE

同志们好!

对寄存器控制问题,

SPRS880F文档的表6-5中,未有任何标注的寄存器为:The peripheral registers can be assigned to either the CPU1 or CPU2 subsystems,也就是说可以受任一CPU控制。然而程序中使用CPU2对I2C-A初始化,均无法写入。

相同的问题还有其它寄存器(技术手册中CPU2可以操作的),

看CPU结构框图(图6-1),发现有个data bus bridge,而在技术文档SPRUHM8I中并没有它的使用说明。

-------------对IPC的写入正确,

谢谢大家!
