Other Parts Discussed in Thread: TLV320AIC3104, ADS7846
大家好，目前我遇到了一个双核通信问题，希望大家帮助。
1.运行环境：IDE: CCSV5 仿真器：XDS100-V2 操作系统：windows11
2.主芯片：OMAPL138 TLV320AIC3104 协议MCASP IIS
3.在Linux环境下调用syslink启动C6748，在加入初始化MCASP函数的时候出现如下警告，请问这是内存一致性问题吗？
出问题的初始化函数如下：
/****************************************************************************/
/* */
/* 动态创建I2C硬件中断 */
/* */
/****************************************************************************/
void I2CIntRegister(unsigned int cpuINT, unsigned int sysIntNum)
{
IntRegister(cpuINT, I2CISR);
IntEventMap(cpuINT, sysIntNum);
IntEnable(cpuINT);
}
告警如下：
+ slaveloader shutdown DSP
Stopped slave procId 0.
Unloaded slave procId 0.
Detached from slave procId 0.
