Hi @samk,
Here is my code. My Microblaze is 150 MHz, and my test resolution is 3840*2160@60Hz.
void RxAuxCallback(void *CallbackRef) {
#ifdef XPAR_XV_HDMITXSS_NUM_INSTANCES
XHdmiC_Aux *AuxPtr;
AuxPtr = XV_HdmiRxSs_GetAuxiliary(&HdmiRxSs);
/* In pass-through mode copy some aux packets into local buffer.
GCP does not need to be sent out because GCP packets on the TX side is
handled by the HDMI TX core fully. Starts storing Aux only when TX
stream has started to prevent AuxFifo Overflow.
*/
if(AuxPtr->Header.Byte[0] == AUX_VSIF_TYPE){
//xil_printf("0x83.Byte[1]:%x\r\n",AuxPtr->Data.Byte[1]);
//xil_printf("0x83.Byte[2]:%x\r\n",AuxPtr->Data.Byte[2]);
//xil_printf("0x83.Byte[3]:%x\r\n",AuxPtr->Data.Byte[3]);
//xil_printf("0x83.Byte[4]:%x\r\n",AuxPtr->Data.Byte[4]);
//xil_printf("0x83.Byte[5]:%x\r\n",AuxPtr->Data.Byte[5]);
//xil_printf("0x83.Byte[6]:%x\r\n",AuxPtr->Data.Byte[6]);
}
else if(AuxPtr->Header.Byte[0] == AUX_AVI_INFOFRAME_TYPE){
RGB_range=(AuxPtr->Data.Byte[3] >> 2) & 0x3;
YCC_range=(AuxPtr->Data.Byte[5] >> 6) & 0x3;
Scan_range=AuxPtr->Data.Byte[1] & 0x3;
Color_format=(AuxPtr->Data.Byte[1] >> 5) & 0x7;
//xil_printf("0x82.Byte[3]:%x\r\n",AuxPtr->Data.Byte[3]);
//xil_printf("0x82.Byte[5]:%x\r\n",AuxPtr->Data.Byte[5]);
//xil_printf("0x82.Byte[1]:%x\r\n",AuxPtr->Data.Byte[1]);
}
else if(AuxPtr->Header.Byte[0] == AUX_AUDIO_INFOFRAME_TYPE){
sample_size = AuxPtr->Data.Byte[2] & 0x03;
sample_rate = (AuxPtr->Data.Byte[2]>>2) & 0x7;
//xil_printf("0x84.Byte[1]:%x\r\n",AuxPtr->Data.Byte[1]);
}
if (IsPassThrough && AuxPtr->Header.Byte[0] !=
AUX_GENERAL_CONTROL_PACKET_TYPE && AuxFifoStartFlag == TRUE) {
memcpy(&(AuxFifo[AuxFifoEndIndex]), AuxPtr, sizeof(XHdmiC_Aux));
if(AuxFifoEndIndex < (AUXFIFOSIZE - 1)) {
AuxFifoEndIndex++;
} else {
AuxFifoEndIndex = 0;
}
if(AuxFifoCount >= AUXFIFOSIZE) {
AuxFifoOvrFlowCnt++;
}
AuxFifoCount++;
}
#endif
}I moved MIG, VDMA,CDMA and BRAM controller to Microblaze D cache port, and RXAuxCallback function worked fine. Is this an issue?
I also found another problem, VPSS ip also affected RXAuxCallback function. If I added VPSS to my BD desgin, HDMI RX didn't receive any infoframes too.
Thanks
Sitting
