Tool/software: TI C/C++ Compiler
Hi TI engineer,
Because our circuit a little change, so AT9 and AP9 is not available, need to output YPbPr signals.But couldn't test the figure.
Hardware: 8168 hdcomp module only answered AT21, AR21, AP21
Software: DVRRDK_04 00.00.03
Question:
1, VGA and YPbPr reuse register? I didn't find.
2,I set ./mem_rdwr.out --wr 0x48108000 0x4402B011,but didn't generated the inner color bar in 8168 for HDCOMP,. Does not meet the AT9 and AP9?
Hi ，
I'm sorry so late to see this information. Thank you for your reply. Output YPbPr didn't solve.
First of all, let me check the following information is normal:
mem_rdwr.out --rd 0x48105ea8 1 ==> 0000 0011
mem_rdwr.out --rd 0x48100118 1 ==> 0000 000F
mem_rdwr.out --rd 0x48140724 1 ==> 0000 0006
mem_rdwr.out --rd 0x48100114 1 ==> 000B 010D
Format is YPbPr output and enable HDCOMP
Code sets hdcomp format is as follows:
VdisPrm.deviceParams[SYSTEM_DC_VENC_HDCOMP].outputInfo.aFmt = VDIS_A_OUTPUT_COMPONENT;
VdisPrm.deviceParams[SYSTEM_DC_VENC_HDCOMP].outputInfo.dataFormat = SYSTEM_DF_RGB24_888;
VdisPrm.deviceParams[SYSTEM_DC_VENC_HDCOMP].outputInfo.dvoFmt = VDIS_DVOFMT_TRIPLECHAN_EMBSYNC;
Vdis_tiedVencInit(VDIS_DEV_HDCOMP,VDIS_DEV_DVO2,&m_vdisPrm);//Binding DVI, DVI output is ok;
I have a waveform by measurement YPbPr, but it may not seem like the normal waveform:
When I remove the input source, YPbPr is no waveform.That there is a video source to the output of hdcomp.
But YPbPr no image out，and then YPbPr to VGA (LMH1251)Image output are as follows:
/home/root/opt/dvr_rdk/ti816x/bin/mem_rdwr.out --wr 0x48108000 0x4402b013
YPbPr has stable output waveform,but YPbPr and LMH1251 don 't output image
I speculated that may be associated with configuration DAC and timing .But I don't know how to confirm this, please tell me how to do.Thank you
Hi Pavel,
I saw some links in HDVPSS document.
"ap-fpdsp-swapps.dal.design.ti.com/index.php
But don't to open it. Have any new links?
