TI中文支持网程序使用了BIOS，SRIO和timer都使用的是CSL配置的中断，但是在把SRIO和timer程加到使用MessageQ Module的BIOS程序中程序跑到MessageQ_open就无法继续跑下去,但是使用的SRIO和timer程序在不使用messageQ module的BIOS程序中自己能够调通，对于遇到得这个问题，我应该怎么办？
Jane Lu：
Hocodrecon,
建议检查一下MessageQ open需要使用的资源是否和SRIO有冲突。 另外，timer也需要检查是否和BIOS默认使用的timer是否存在冲突。
另外，BOIS管理的中断资源和CSL管理中断是否冲突？
hocodrecon：
回复 Jane Lu:
加上timer 或者SRIO之后，中断的方式是可以成功的，但是MessageQ open 不能用。这样的话BIOS管理的中断资源应该与CSL库的没有冲突吧。
对于检查MessageQ open需要使用的资源是否和SRIO有冲突，麻烦你说的具体一些。

注意到Timer相关部分使用了如下代码：

该代码重置了中断的配置。 请打开BOIS的配置文件，看一下默认使用了哪些中断，更改Timer代码中相应的中断不去覆盖BOIS使用的资源。

intc的中断管理和BOIS的中断管理还会可能有其他冲突，不建议同时使用。

cgf文件中的配置如下，其他和中断相关的就没有了。
var ECM = xdc.useModule ("ti.sysbios.family.c64p.EventCombiner");var C64_Hwi = xdc.useModule ("ti.sysbios.family.c64p.Hwi");
var CpIntc = xdc.useModule('ti.sysbios.family.c66.tci66xx.CpIntc');var Swi = xdc.useModule('ti.sysbios.knl.Swi');
ECM.eventGroupHwiNum[0] = 7;ECM.eventGroupHwiNum[1] = 8;ECM.eventGroupHwiNum[2] = 9;ECM.eventGroupHwiNum[3] = 10;
timer使用的是interrupt 9
我把
_CSL_intcCpuIntrTable.isr7 = _CSL_intcNmiDummy; _CSL_intcCpuIntrTable.isr8 = _CSL_intcNmiDummy; _CSL_intcCpuIntrTable.isr9 = _CSL_intcNmiDummy;_CSL_intcCpuIntrTable.isr10 = _CSL_intcNmiDummy;
注释掉了，还是不行，
其他程序也是上边的配置，但没有使用MesssageQ 就没有问题。

回复 Jane Lu:
timer的程序相对简单一些，我把它改成用SYS/BIOS的方式
修改后的代码如下：
Hwi_Params hwiParams; Error_Block eb; Hwi_Handle myHwi; Hwi_Params_init(&hwiParams); Error_init(&eb); // set the argument you want passed to your ISR function hwiParams.arg = 1; // set the event id of the peripheral assigned to this interrupt hwiParams.eventId = 0x42; /* Enable the Hwi */ hwiParams.enableInt = TRUE; // don't allow this interrupt to nest itself hwiParams.maskSetting = Hwi_MaskingOption_SELF; myHwi = Hwi_create(11, TimerInterruptHandler, &hwiParams, &eb);
麻烦看一下对不对，
最开始使用的vectorID9,而不是11，结果是如下
[C66xx_0] ti.sysbios.family.c64p.Hwi: line 159: E_alreadyDefined: Hwi already defined: intr# 9ti.sysbios.family.c64p.Hwi: line 234: E_handleNotFound: Hwi handle not found: 0x89c6e8xdc.runtime.Error.raise: terminating execution
后来才改成11 的，是不是因为ECM.eventGroupHwiNum[2] = 9;所以就不能用了呢？
但是改成11之后，timer的用中断的方式可以实现，但是程序继续往下进行就成了下边的样子

这又是怎么回事呢？
我看到的程序上 eventID 使用函数Cpintc_getEvent得到的，我这里是直接用 用CSL方式配置的eventsID，什么时候应该用前边的函数得到呢？

hocodrecon,
从打印信息上来看，代码PC指针跑到0x0地址了。 NRP=0x0指示异常代码PC地址为0地址。
错误是进入TIMER中断之后马上产生的吗？ 能单步跟一下为何进入0地址？
