Part Number:TDA3XEVM
Hi ,
I need to use TDA3X display subsystem with sysbios os to get YUV420-NV12 to RGB 888. for that i configured Dss system for following steps.
1)Enable the Dss module clk by CM_DSS_DSS_CLKCTRL ->0x4A009120
1)Configured Dss clock by DPLL_EVE_VID_DSP(VID_PIX_CLK) and DLL_PER module(DSS_GF_CLK) 75Mhz
2)Configure Video port & configure interrupt for program scan line number and vsync , mipi Dpi interface enabled.
Disabled BT 656,1120,STALLMODE,Auto refresh off. Configure proper LPP,PPL all parameters.Enabled VP port.
3)Configure video VID1 pipeline for NV12 format.configure filter and csc coefficients.Enable full range,
channel out to overlay 1 & video port. Enable video1 pipeline.Disable the Dma .Given NV12 Y & UV buffer address
4)overlay not configured.
4)Enabled interrupt from irq crossbar ,Configure picture position x & y to 0.Configure proper VID size.Configured VP interrupt & enabled.
Output:
I got the interrupt only once when I enable the interrupt.
ist I received program scan line interrupt and then vsync interrupt
but after that i am not getting any interrupt. and Go bit is not getting cleared.
How should i debug which module is giving problem and Is I enabled all clock properly?
please reply urgently.
