The platform is DM8168 EVM + Daughter Card + DVRRDK3.0
The Arm side, I change the code fllow:
helloWorldPrm.inQueParams.prevLinkId = ipcFramesInDspId;
helloWorldPrm.inQueParams.prevLinkQueId = 0;
helloWorldPrm.maxStride= 1920*1080*2;
helloWorldPrm.maxWidth= 1920;
helloWorldPrm.maxHeight= 1080;
helloWorldPrm.createOutBuf1= 1;
helloWorldPrm.maxChannels= 1;
helloWorldPrm.numBufsPerCh= 1;
The DSP side in the HelloWorldLink_processData function of helloWorldLink_priv.c, I change the fllow:
UInt8 *p = pFrame->addr[0][0];
UInt32 curTime;
curTime = Utils_getCurTimeInMsec();
UInt32 YUV_test;
for(YUV_test = 0; YUV_test < 1920*1080*2; YUV_test ++ )
{
int mod = YUV_test % 4;
*(p + YUV_test)= 0xff;
/*if(mod == 0)
*(p + YUV_test)= 0xff;
else if(mod == 1)
*(p + YUV_test)= 0x80;
else if(mod == 2)
*(p + YUV_test)= 0xff;
else if(mod == 3)
*(p + YUV_test)= 0x80;*/
}
Vps_printf("This is test point 67!!! ****HelloWorldLink_processData*****%d********%x*****%x*********\r\n\n\n",Utils_getCurTimeInMsec()-curTime,*p,*(p+1920*1080*2-1));
The problem is :
when I used memset(pFrame->addr[0][0]),0x0f,1920*1080*2),there is no problem.
when I used 'for' circulate, used *(p + YUV_test)= 0xff; to change a frame data ,there is also no problem.
but when I use 'for' circulate, and used shield code, the system is down. the log is fllow:
