TMS320F28388D: 关于28388D CPU2中SCI通信

老师您好，我最近在做28388D核间通信，现在实现的功能是将一组数据通过IPC从CPU1发送至CPU2，CPU2再使用SCIB将这组数据发送出去，但目前数据在通过SCIB发送的时候出现了问题，不能发送成功，现在将CPU1和CPU2中的代码贴出，希望老师可以帮忙寻找一下问题，非常感谢

我在device中对如下引脚进行了定义

#define DEVICE_GPIO_PIN_SCIRXDB 11U // GPIO number for SCIB RX
#define DEVICE_GPIO_PIN_SCITXDB 10U // GPIO number for SCIB TX
#define DEVICE_GPIO_CFG_SCIRXDB GPIO_11_SCIB_RX // "pinConfig" for SCIB RX
#define DEVICE_GPIO_CFG_SCITXDB GPIO_10_SCIB_TX // "pinConfig" for SCIB TX

非常感谢老师

你的程序有参考C2000Ware的例程吗？C:\ti\c2000\C2000Ware_4_03_00_00\driverlib\f2838x\examples\c28x\sci
