关于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

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(¶ms);
//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, ¶ms, &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！

Biios及非bios下中断配置参考：http://processors.wiki.ti.com/index.php/Configuring_Interrupts_on_Keystone_Devices
搬完数据后如果不能产生中断，先check一下相应IPR bit是否置位，如果已经置位，则说明EDMA搬移数据正常，说明与中断配置有关；由于EDMA ISR是路由到CPINTC，在中断响应函数中需要清system event，清IPR bit，然后才能保证响应接下来的中断。
