6678 多核访问EDMA 冲突问题

使用不同的parameter set，以及中断事件的映射；最好你把两个核上的EDMA配置代码贴出来看看

您好，部分代码如下

//define EDMA3 instances
#define CSL_EDMA3 CSL_EDMA3CC_1

//region
#define SP_CORE0_EDMA_REGION CSL_EDMA3_REGION_0
#define SP_CORE1_EDMA_REGION CSL_EDMA3_REGION_1

//channel
#define SP_CORE0_FFTDATAIN_EDMA_CHANNEL 33
#define SP_CORE1_FFTDATAIN_EDMA_CHANNEL 34

//tcc
#define SP_CORE0_FFTDATAIN_EDMA_TCC SP_CORE0_FFTDATAIN_EDMA_CHANNEL //chain to self
#define SP_CORE1_FFTDATAIN_EDMA_TCC SP_CORE1_FFTDATAIN_EDMA_CHANNEL

//param set
#define SP_CORE0_FFTDATAIN_EDMA_PARAM 1
#define SP_CORE1_FFTDATAIN_EDMA_PARAM 2

//queue

还有一个问题：就是中断未响应，敬请赐教，工程在BIOS下，edma_config做了CPINTC 的映射配置

Int main()
{
Task_Handle task;
Error_Block eb;
Int intNum;
Hwi_Params params;

System_printf("enter main()\n");

edma_config(DNUM);

Error_init(&eb);
task = Task_create(taskFxn, NULL, &eb);
if (task == NULL) {
System_printf("Task_create() failed!\n");
BIOS_exit(0);
}

// Initialize the Hwi parameters
Hwi_Params_init(&params);

//FFTIN
// Set the GEM event id in the params
params.eventId = 21;

// Specify the interrupt vector number
intNum = 4;

/* When using CpIntc, you must plug the Hwi fxn with CpIntc_dispatch */
/* so it knows how to process the CpIntc interrupts.*/
Hwi_create(intNum, &CpIntc_dispatch, &params, &eb);

BIOS_start(); /* does not return */

return(0);
}

总结一下中断配置：两核用了相同的中断事件EDMA3CC1 CCINT0 （ps:同一类型的EDMA搬移8核使用相同的edma完成中断事件，不同类型EDMA搬移选择不同edma完成中断事件），即edma中断完成事件，，在CIC0输入为8号事件，通道映射核0输出为32，核1输出为43，对应的GEM event id  都是21，再有INT4输出给CPU，两核有各自的中断服务子程序

希望我的叙述没有让您觉得混乱，期待您的解答

谢谢！

hi,

现多核冲突已经解决，我将上述中断部分代码改写为在非 BIOS 下，发现只能响应一次中断，就是刚上电运行能进入中断，之后再执行EDMA 搬移或者 restart 均无法进入中断。请问这是哪方面原因造成的？还有就是BIOS 下依然无法响应中断，请问BIOS 下我的中断配置是否正确？

谢谢！
